城市是人类社会经济文化发展到一定阶段的产物。城市起源的原因和时间及其作用，学术界尚无定论。一般认为，城市的出现以社会生产力除能满足人们基本生存需要外，尚有剩余产品为其基本条件。城市是一定地域范围内的社会政治经济文化的中心。城市的形成是人类文明史上的一个飞跃。
一、城市规划的任务
我国城市规划的任务是：根据国家城市发展和建设方针、经济技术政策、国民经济和社会发展长远计划、区域规划，以及城市所在地区的自然条件、历史情况、现状特点和建设条件，布置城市体系;确定城市性质、规模和布局;统一规划、合理利用城市土地;综合部署城市经济、文化、基础设施等各项建设，保证城市有秩序地、协调地发展，使城市的发展建设获得良好的经济效益、社会效益和环境效益。
各国城市规划的共同和基本任务：通过空间发展的合理组织，满足社会经济发展和生态保护的需要。从城市的整体和长远利益出发合理有序地配置城市空间资源;通过空间资源配置，提高城市的运作效率，促进经济和社会的发展;确保城市的经济、社会与生态环境相协调，增强城市发展的可持续性;建立各种引导机制和控制规则，确保各项建设活动与城市发展目标相一致;通过信息提供，促进城市房地产市场的有序和健康的运作。
二、城市规划的发展
城市的发展是人类居住环境不断演变的过程，也是人类自觉和不自觉地对居住环境进行规划安排的过程。在中国陕西省临潼县城北的新石器时代聚落姜寨遗址，我们的先人就在村寨选址、土地利用、建筑布局和朝向安排、公共空间的开辟以及防御设施的营建等方面运用原始的技术条件，巧妙经营，建成了适合于当时社会结构的居住环境。可以认为，这是居住环境规划的萌芽。要实行规划区范围内全覆盖规划，统筹城乡发展，规划在保护自然生态环境基础上，重点突出中心城区职能、空间结构的调整与优化，合理确定和强化各组团产业依托，切实改善城镇生产、生活环境，推进村屯用地结构性调整。规划期内，逐步实现退宅还耕、退宅还林，促进农村人口向中心村、城镇集中;逐步缩小城镇与中心城区的差距，促进小城镇由数量型向质量性转变;逐步发展壮大组团，与中心城区形成联系紧密、资源互补的城市空间。最终实现城乡一体、协调共生的城市发展格局。突出社会公益设施建设，统筹经济与社会发展，规划健全各类公共服务设施，建立合理的级配体系;发挥公共投资导向性作用，促进规划区空间结构的形成和发展;进一步完善中心城区省会服务职能，加强现有城市中心的商业、文化娱乐等公共服务职能;努力促进以信息、金融等现代服务业为主的南部新中心的形成;结合市级文化、会展、体育等专项服务中心的设置，带动分区级中心形成与发展;以建设文化名城为目标，促进公益性文化事业繁荣兴旺，推动经营性文化产业蓬勃发展，全面提高社会文化生活质量。
三、城市发展中存在的问题
我们的城市发展还存在一些问题，比如盲目争建国际化大都市;盲目争建中心商务区;盲目追求高层建筑;盲目建设大量城市雕塑等，以上盲目的做法其实是城市在经济发展过程中不成熟的表现。明确城区发展方向，促进分区发展，为加快经济发展，促进城区、开发区和县域经济发展，在开展大量前期研究的基础上，提出了各城区、开发区的发展方向和功能定位。进一步调整能源消费结构，提高使用清洁能源的比重，发展集中供热，加强对汽车尾气的治理，综合整治大气污染。加快城市污水集中处理设施和城市垃圾无害化处理设施的建设。大力保护和改善生态环境，要保护好已有植被和各组团之间生态防护绿化带，进一步提高城市绿化覆盖率。要加强城市环境综合整治，改善城市生态环境。
四、城市景观规划的具体做法
城市景观规划是城市规划的一个重要环节，根据不同的地区，有不同的地理环境和人文历史。所以，城市景观规划要根据实际情况来设计和计划。要有选择，有目地，有侧重点的进行建设。具体的做法有以下几点：
1、确定景观的活跃元素
在分析了景观的基础上，寻找此景观的特色，最具历史意义的景观风貌，作为此景观的主角。这也是创造文明城市的根本所在。
2、划分特色景观区
要根据城市景观的特色和地理位置的功能进行建设，并渐渐的强化它的特色，从而继承和发扬城市的历史文化。
3、组织轴线景观
这要通过城市的主要干道来决定。
4、控制景观视廓
景观视廓就是为了使各个景观处于通透的状态，在各个方向都能欣赏到，而建立起来的景观走廊。
5、勾勒城市天际线
城市天际线是指自然景观和人工建筑物等形成的轮廓线。天际线轮廓应和景观视廓相配合，相协调。
五、城市景观要素
城市景观要素包括人工景观要素和自然景观要素。其中人工景观要素包括广场、建筑物、集贸市场、园林绿化、艺术小品、文化遗址。那么，自然景观有，大小山丘，石头、湖泊、海洋、古木名树。这些景观为文明城市做了重要的贡献，提高了人民的生活水平，陶冶了人们的情操。
六、经济发展与环境建设的关系
要处理好城市经济发展和环境建设的辩证关系。注意保护和改善城市生态环境，防止污染和其他公害，加强城市绿化建设和市容环境卫生建设，保护历史文化遗产、城市传统风貌、地方特色和自然景观;不能片面追求经济效益，以污染环境。破坏生态平衡、影响城市发展为代价，避免重复“先污染，后治理”的老路，而要使城市的经济发展与环境建设同步进行。人与环境是相互依存的有机整体，保持人与自然相互协调，既是当代人类的共同责任，也是城市规划工作的基本原则。
七、结语
城市的发展越来越快，人们的生活水平越来越高，城市规划成了社会的追求。城市研究任务艰巨而纷繁，这也说明它丰富的活力。城市永远在发展，城市问题也总是相伴而生，但人类必将更为自觉地运用广泛的知识与丰富的想象力、创造力，发展城市环境的规划、建设和管理。城市规划工作从最初社会经济发展的战略研究起，最终要落实到物质建设上，形成供人们生活和工作的形体环境。
城市规划是建筑和园林建设的前提，并为所需的空间准备条件，城市规划研究的进展也为建筑学和园林学的开拓提供了前所未有的广阔天地。规划师与建筑师、园林设计师的工作目标是一致的。随着人类社会的发展，这三学科的有机结合和协同创造，势必将形体环境的建设推向更高的境界。

摘要：人类社会发展正面临着人口膨胀、资源超前消耗、环境急剧恶化的空前挑战，可持续发展理念指导下的的现代城市规划，决定了我国的大部分地区只能追求以公共交通为基础的高质量的可达性。具有多项显著优点的轨道交通(尤其是地铁运输模式)，是解决大城市中心区域交通拥堵问题的最佳途径，但必须在依托改善既有公交系统、并通过优化网络便捷换乘而达到相互协调配合的前提下，注意降低它的建造运营成本。 关键词：可持续发展；城市规划；轨道交通；建造运营成本 作为文明历史发展中的崭新时代，城市的诞生宣告了人类生存方式的彻底变革，也由此开创了城市建设与规划的初始形态。今天，伴随全球化的大潮，中国正经历着前所未有人口迁移与国土城市化过程，充满中国特色的城市规划实践，越来越体现出面向未来可持续发展的先进理念。交通是现代城市规划中一个不可或缺的方面，对于中国这样一个各方面处于跳跃式发展的人口大国，科学地制定切合实际又具有前瞻性的城市交通规划，意义尤其重大深远。 本文以当前城市化加速背景下城市交通规划面临的重大选择作为切入点，对如何解决轨道交通与现存城市公交系统的协调发展，特别是如何经济、优化地建造与运营城市轨道交通，提出自己的看法与建议。 1 轨道交通是我国城市交通规划的重大选择 城市交通规划面临的一切问题起源于三个基本因素：人口剧增、城市化加谜与出行方式机动化。为此，规划者们必须在各种可能的决策方向之问慎重取舍。国外专业杂志《世界城市化展望》2004年载文指出，全世界人口从1950的25亿左右增长到2000年60多亿，只用了半个世纪的时间，预计再过30年将达到80亿以上。作为世界最大的发展中国家，中国改革开放二十多年来的社会经济发展带动了1亿3千万农村人口流入城市，一般城市居民的交通出行方式也在过去二十多年里发生了根本性的变化。城市出行方式机动化日益加速，造成了今日中国主要大中城市里司空见惯的“出门难行路难”问题。专业人士称之为严重的城市道路交通拥挤。 一般而言，城市交通方式大致可分为步行、自行车、摩托助动车、小汽车与公共交通国内外的城市交通基本上都经历过从步行、自行车到摩托、小汽车大体相同的发展过程。但是，当人类普遍进入小汽车时代后，美国和欧洲选择了不同的交通方式和城市形态。美国以小汽车为主要交通工具，城市多数呈现分散、蔓延的形态。欧洲大陆则十分重视公交、特别是轨道交通，大城市通过轨道交通将市中心、近郊生活就业区与远郊卫星城镇连结起来，形成多中心的城市形态[1]。轨道交通系统的诞生，使城市的发展从中心聚集型向离心分散型转变成为可能，也因此造就了城市中心的“职住分离”现象。应该承认，私人小汽车和轨道交通是目前发达国家城市中具有代表性的两种交通方式，分别突出地体现着更优的生活质量与更高的运输效率。改革开放前，这两种交通方式在我国大城市中的数量少到几乎可以忽视不计的程度，近年来，它们已分别迈出了从无到有的第一步，表现_出强大的生命力。 城市的功能和社会活动的多样化是大城市的基本特征，由此决定了大城市的交通需求必然是多种多样的，人们可选择的出行方式也应该是多种多样的，并且所有的出行方式都可以在各自适用的范围内发挥出最大优势口[2]。我国的城市交通机动化正处于起步状态，自行车等非机动车仍是目前大部分城市中居民出行的主导方式。随着社会经济持续、快速增长与人民物质文化水平不断提高，建立多层次、立体型多元化的交通体系，是我国数量迅速增长的大城市的唯一发展方向。在此目标之下，科学规划的轨道交通理论上提供了最大限度满足可持续发展要求的可能性。 城市交通拥挤现状，决定了各级政府部门在宏观决策过程中，理当重点考虑规划在环境系统、资源系统、社会系统等多方面具有可持续发展优势的城市轨道交通公共交通系统[3]，这方面国内刊物近来论著颇多，本文不欲在此重复赘述。以下谨从技术与经济的角度，探讨进一步解决轨道交通建设面临的一些具体问题，加速走向它的现实可行性。 2 轨道交通需重视与城市公交系统的和谐 一般而言，轨道交通规划工作的核心内容是要充分实现路线选址与转乘配套两者的最优化，与现有的公交系统在各个环节上达到最大限度的互相补充协调运作。 首先，城市轨道交通是一项涉及面广泛复杂、需要许多专业协调配合的大型系统工程，必须与城市建设发展中长期规划密切结合起来进行。作为城市规划的有机构成部分，轨道交通的规划与整个城市交通的线网规划实为一体。为了避免客流稀少，线路走向应尽可能合理，否则，小客流低运量必然导致轨道交通无法发挥预期的骨干作用。总之，结合城市的总体客运需求合理规划布局，是保证城市轨道交通主导地位的必要条件。当然，这种合理布局要充分考虑不同城市的用地空间总体规划。北京地铁线明显采用了沿城市道路走向布局的方式，轨道交通网络形态与市区道路棋盘式格局高度一致，恰恰体现了保护北京古城的特殊要求。这方面类似的例子，还有南京地铁1号线采用高架方式从中华门附近跨越古城，也充分考虑了地下车站与周围环境、高架线路与地面景观的协调需要。 其次，在以轨道交通为主导编制城市公交综合规划时，要十分注意加强交通换乘枢纽的建设，将轨道交通与现有的常规公交体系统一安排、有序调整，保证轻轨、地铁等轨道交通与城市公共汽车、出租车、轮渡等多种交通工具的方便转接，以及与机场、火车站、港口等其他运输场所的顺利衔接。前文所举的欧洲发达国家的大城市，面对小汽车交通的冲击，纷纷寻求一种新的交通发展模式，在通向郊区的沿线地铁站大量修建小汽车停车场，引导小汽车乘客换乘后进入中心城区，使轨道交通的大运量优势得以发挥。国内方面新近建成的上海火车南站，则成功地将铁路与两条城市轨道交通与几十路近、远郊公交汽车线的零距离换乘需要融入规划设计中，成为一个值得学习借鉴的样本。 最后，我们不能不充分注意轨道交通与整合改善城市常规公交之间的互动关系。世界上绝大多数国家的轨道交通都是在既有城市公交体系形成后逐渐发展起来的。在未来相当长一段时间内，公共汽车／电车仍将是人们出行使用较广泛的交通工具之一。根据我国许多城市目前的经济发展水平与人口规模及交通总量需求，常规公交的整体地位短期内变化不大。但是，常规公交系统效率低下的现状应该在逐步发展轨道交通的过程中加以综合整治与改善。除了科学制订线网布局，修建港湾式停靠站台，合理编制车辆运行图，建设服务查询显示信息系统等具体措施外，从规划立法角度保障公交的道路优先使用权的思路也有待于细化落实。 近来，在轨道与公交配套发展背景如何建设大容量快速公交系统(BRT)引起了专业规划人员的高度关注。BRT是一种利用现代化大容量专用车辆、在专用道路空间快速行驶的一种公交方式。它具有接近轨道交通的运力与快捷，建造和运营成本又相对低廉，而且很大程度上可以利用改造提升现有的城市公交道路系统，在某些人口规模不是很大的城市中甚至可以考虑作为轨道交通的替代方式。 2003年国务院81号文件出台后，国内许多城市马上把发展BRT项目推到了缓解城市交通拥堵的前台。北京市新近编制的中心城区公共汽／电车厂线网规划中包含了18条BRT线路，总长约300多km，在强调机动性与可达性高度协调的前提下，首次将BRT作为一个功能层次融人公交线网整体结构中。此外，昆明市在园艺世博会期间开通的国内首条位于道路中央的公交专用道，即将升级为规范的现代BRT系统。杭州根据城市发展模式与空间功能布局制订的中远期公交规划，也确立以轨道与BRT为骨干，东西走向穿城而过的首条28 km BRT今年已基本开通。 3 轨道交通应解决低成本建造运营问题 作为城市中最大的基础建设项目之一的城市轨道交通投资巨大，京、沪、穗前几年修建地铁的综合造价平均每千米超过了6亿元人民币。显然，大多数国内城市的经济能力很难承受起如此高昂的成本。因此，不解决轨道交通的造价问题，城市轨道交通难以实现。综合考虑轨道交通的建造与运营费用，笔者以为解决成本问题拟应围绕以下三个方面认真思考。 3．1 轨道交通的用地空间应体现预留渐进原则 一般轨道交通建设成本中，包括拆迁费用在内的占用土地成本是其中不可忽视的一个组成部分，并不因为某些国家无偿划拨方式而改变它的社会成本性质。为了降低这方面的成本，许多城市在已经完成的公交总体规划中，都为轨道交通的线路场站建设预留了用地空间。然而，线路建设的具体时机取决于城市发展的不同进程，某些线路的客流形成需要一个长期渐进的过程。 因此，如何既能适应逐渐增长的客流需要，又能合理有效地利用预留土地空间，是低成本发展轨道交通中必须慎重规划考虑的现实问题。在巴西的大多数城市里，市政当局大都在轨道交通近期没有开发的走廊上发展前文介绍的快速公交，将BRT专用道建在道路中央，初衷就是为了降低轨道交通项目的初期投资与运营费用[4]。实际上，北京2005年全线通车的第一条BRT线路，正是敷设在预留的M8轨交走廊上，完全满足了近期单向8 000人次／h的客流需求。 经济合理地使用土地空间，不仅需要作为城市规划中发展轨道交通的指导原则加以确立，更应当具体落实在轨道交通系统工程的每一个子项目的设计图纸上。根据《上海市城市总体规划1999—2020》，到2020年将建成800 km左右轨道交通线，如果全都继续采取目前的集中供电模式，届时仅该项子系统就需建造50多座主变电所。 暂且不论一座主变电所动辙上亿元的巨额投资，仅建造变电所及电缆通道所需占用消耗的土地资源就将十分惊人。有鉴于此，最近上海相关部门已组织专家进行优化方案论证，将2020年前全网18条线路原先计划建造的51座主变电所减少为39座，更可节约投资10亿元人民币以上。 3．2 轨道交通的建造模式要体现经济合理原则 世界城市轨道交通近百年的历史展现了丰富多彩的发展模式，为我们提供了地铁轻轨、导轨、有轨电车、郊区铁路、磁悬浮等多种选择模式，线型电机牵引系统则被公认为最有发展前途的一种在我国百万以上人口的城市中，因地制宜地利用现有条件低成本发展轨道交通，已有了一些成功的经验。上海的明珠轻轨一期有3／4长度是改造利用原先的铁路内环线，这对武汉等其他一些存在废弃或利用率很低的铁路既有线路城市，不啻是一种有益的启发与示范。另外，东北沈阳、长春、哈尔滨等城市，还存有部分有轨电车线路[5]，在此基础上统一规划发展现代轨道交通，应该也能够达到节省一部分费用成本的目的。 其实，国内城市轨道交通建设成本居高不下的原因之一，还在于脱离国情片面追求豪华档次。表现在规划设计上就是大量采用类似于公共汽车系统的高线网密度、小站间距、低负荷强度。需知，轨道交通本质上属于快速大量运送中长距离乘客的交通工具，依靠其他交通工具为它输送客源，达到大运量高负荷。由于低线网密度、大站间距模式能够明显提高运行速度、缩短旅行时间，所以不但可以降低工程造价，而且还可以降低运行成本。正因为如此，将BRT系统规划为轨道交通线路两端的延伸段，或选择“轨交+BRT”的混合网络模式，都有助于达到适当降低轨道线网敷设密度的低成本目标。 另外，国内轨道交通运营成本高的部分原因，还与计划经济遗留下的传统思维方式与条块分割的管理模式密切相关。直到今天，许多城市在申请轨道交通立项时，每条线路都规划有独立使用的车辆段、控制中心、主要变电站，这套小而全的空间与管理体系必然造成资源的极大浪费。在轨道交通十分发达的日本，帝都高速交通营团运营管辖着8条线路总长183．2 km，但是所属16个车站统共只设置了1座综合控制中心。反观国内，即使在资源共享程度较高的上海地铁系统，已建和待建的控制中心仍有8座，另加1座轨道交通运营协调及应急中心。 3．3 轨道交通的管理配套要体现因地制宜原则 如前所述，城市轨道交通的规划不应盲目追求高标准，该建地面、高架的绝不钻入地下、该建轻轨的绝不建地铁，因为后者的造价往往是前者的3倍以上。此外，对地铁建设成本影响甚大的土建工程中，其地下车站底板的埋置深度与车站建筑高度是决定造价大小的两个关键因素。因此，合理设计基坑深度与车站建筑高度对降低总成本的意义，无论如何也不应低估。 如果说轨交模式、建造标准的选择较多地影响到土建工程造价部分，轨道工。程总造价的另外一半(45%～50 %)则取决于技术装备等硬件的建设、购置、安装费用。以地铁车辆为例，目前国产价格仅为进口产品的1／2～1／4。因此，降低成本费用的关键之一，是提高构成技术装备主要部分的车辆、牵引、供电、信号的国产化水平。这方面，较晚竣工投入使用的南京地铁为我们提供了很有说服力的例证。据有关杂志介绍，该项目通过车辆项目的合同谈判与国产化方案的慎密调整，大大减少了进口部件和材料，降低了进口设备的国际运输成本，在成功实现70 国产化率的情况下，车辆项目合同价从最初的每辆约135万美元降低到116．5万美元，与设计概算相比节约投资4 000多万人民币。 当然，轨道交通总体上属于公共产品领域，单纯的票务收入远远不足以偿付开通后的日常性运营支出，中长期的财务收支平衡对世界各国都是一个需要艰难应对的挑战。笔者了解到的香港地铁总收入中，票务收入约占60 ，其余40 9，6中广告与物业管理各占一半[6]，这一香港较为成功的地铁和物业综合发展经营模式，今年初已通过成立中港合营公司引入北京地铁4号线的管理，各方都期待着它能为国内轨道交通建设运营展示一种令人鼓舞的前景。 参考文献 1 邹胜勇．面向可持续发展的城市总体交通结构优化[J]．交通运输系统工程与信息，2006，6(2)：108． 2 David

Ecological areas of space rational structure, improving infrastructure, ecological construction, intelligent buildings and building life should be widely Use artificial environment and the natural environment integration. It is consistent with urban planning and regional planning, and regional and urban harmony, is part of the ecological city, the host city and embodies characteristics. Key word: Ecological house design 1 The ecological characteristics of small content Ecological habitat areas through adjustment of ecological environment ecosystems and ecological factors, the area has become a natural ecology and human ecology, natural and artificial environment, a high degree of unity of material and spiritual civilizations, the ideals of sustainable development of urban settlements. Ecological areas of space rational structure, improving infrastructure, ecological construction, the widespread application of smart buildings and the construction of life, artificial environment and the natural environment integration. It is consistent with urban planning and regional planning, and regional and urban harmony, is part of the ecological city, the host city and embodies characteristics. Compared with the traditional areas of ecological areas was essentially different from the following features: cohesion D symbiotic ecological areas within the natural and human, human to natural, intimate nature, natural into the residential areas into natural; At the same time, to create the environment to meet human needs of their own development, a human face, full of strong cultural atmosphere, mutual assistance groups have strong attractive, showing a prosperous, vigor and vitality. Area D ecological sustainability guided by sustainable development, and thus it can achieve small social, economic and environmental development, to achieve social and environmental benefits at the same time promoting economic development, and achieve rapid economic growth of high quality; Natural resources as a small public area can be used for a long, long time. Area D is not simply the pursuit of the overall ecological environment or Own prosperity, but also a social, economic, environmental overall coordination among development, nor is a small ecologicalization the ecologicalization, but overall the area of ecological and achieve overall ecological civilization. Therefore, the ecological residential building our cities will gradually change the current building environmental pollution, lack of effective environmental protection unreasonable status quo and achieve energy savings, and section, water conservation, pollution, and the effective management of the property to improve the environment of cities and areas have their own powerful dynamic. 2 Ecological planning content areas (1) Ecological district planning objectives UN Man and the Biosphere Programme No. 57 report pointed out: "It is natural ecological planning ecological and social psychological aspects of the two to create a fully integrated technology and natural human activity optimal environment induced human creativity and productivity in high material and cultural standard of living. "According to this description, We ecological areas can be understood as planning objectives : to ecology "as a whole, coordination, circulation, renewable" principle as a guide, through the promotion of eco-design methodology Habitat improvement of the quality of the environment and people in harmony with the natural, artificial and natural facilities coordination, and achieve small social-economic-natural complex system as a whole to achieve a coordinated and stable, balanced, orderly state of evolution. (2) ecological district planning methods The use of eco laws aiming at sustainable development, to engineering measures and technical means to support the traditional sense small design planning to become a real estate ecological areas to areas of ecological civilization advance the sustainable development of cities. (3) the content of the ecological area planning Including small ecological planning, economic planning and social ecological ecological planning. 1, ecological planning! Green indicators: The indicators are measured Ecological district level building the most important indexes. Green belts (including node and surface) to more than 50%, the per capita public green spaces in more than 28 square meters. Ground water indicators : indicators that the water seepage capacity building bases to minimize concrete coverage, the use of natural drainage systems to facilitate rainwater infiltration, the ideal target is 80% of the surface area of flooding to properties. Water-saving targets the targets for the development of alternative water resources (revenue) and the provincial water apparatus use (cut), as the main water-saving methods. The former refers to the design of residential buildings or use force rain water purification system design, which means that rain, life-pooling processed, the required water quality standards, duplication in the use of non-potable water and non-physical contact with the complex water. Energy conservation targets : to design energy-efficient buildings through air-conditioning systems, lighting, night-ray use, the use of solar energy and other means. CO2 and waste reduction targets : the application of indicators to encourage Qinglianghua architectural structures, such as the use of steel construction to reduce construction sand Stone, brick and other building materials; Promote home simple interior designers, building materials recycling to achieve energy conservation, provincial resources, reduce waste and reduce carbon dioxide emissions. Sewage treatment indicators: the former for construction of storm water, sewage diversion pipeline systems, on the one hand facilitate the recycling of rainwater, on the other hand, could reduce the volume of sewage treatment. The latter refers to refuse collection and classification of resources recycling. Green traffic indicators: a clean, suitable for the urban environment, health useful means of transport to complete socio-economic exchanges. According to Taiwan with the use of green transport assessment, foot, bicycle, Light Rail, trams, etc. score 40 or more, and ordinary buses, trucks, motorcycles, scored in the following hours. Therefore, ecological areas green transport planning should encourage residents to use green transport. 2, economic ecological planning! The overall objective is to resource consumption and environmental pollution to the light of the rapid economic growth and cultivating scientific civilization consumption patterns. For this purpose, the application of green technology and green consumption production technology, and gradually change the energy structure, accelerate renewable energy alternative to fossil energy, applications hydropower, wind, biomass, solar and other green energy; Using natural ventilation and natural lighting and reduce energy consumption; In the area of production of green, green consumption. 3, the social ecology planning to enhance the sense of belonging and a small landmark, a center of the square and the charm of the inhabitants frog space; Supporting the establishment of complete, rationally ecological infrastructure, the creation of various age groups to facilitate crowd living environment; Area provide diversity, individuality residential, to ensure that all economic income people and people of various age levels demand; small commercial activities, public services, cultural activities, recreational activities, the center concentrated areas. In short, ecological planning of new residential areas is a concept and a vision for the future of urban targets will be the ideal leisure parks and sustainable urban development trend of the future residential area. It is a magnificent building integrated engineering; we need long-term and unremitting 、The ecological residential contents Ecological residential has a strict technical standard, developers can not arbitrarily self-styled. Ecological residential demand in the energy and water, gas, sound, light, heat and the green environment, waste disposal, building materials and other aspects of the nine national standards. 1, in the energy system, should avoid multiple pipelines into people's homes, the wall structure of residential energy-efficient design and reversal system and encourage the use of solar, wind, geothermal, maintaining appropriate indoor temperature, indoor temperature in the winter. 2, the system called for the establishment of outdoor aquatic environment sewage reuse rainwater collection system and use the system, indoor and outdoor use of water saving devices, the use of water-saving landscape water systems. 3, gas environment to the secondary system for the outdoor air quality standards, indoor ensure natural ventilation, ventilation ventilation facilities with bathrooms, kitchens have gas emission concentration system to the larger national air quality standards. 4, sound environmental systems, Architectural designs have noise Jiangzao measures for outdoor daytime noise 50dB, less than 40dB noise at night, less than 35dB noise indoor day, night noise less than 30 , optical environmental systems meet the requirements of interior design sunshine hours, try using natural light; indoor, avoid light pollution, such as glare advertising, curtain walls; indoor application of energy-saving lamps, and promote the use of solar green lighting. 6, ecological residential use has also requested approval of the National Environment Commission approved the award of the environment and surrounded by the signs of building materials to meet the non-toxic, harmless, non-polluting, non-radioactive, non-volatile requirements, the use of 3R (reusable, recyclable use, renewable use) materials. Small green environment is an important theme of ecological residential, while living in the garbage disposal is a major part of a . For residential ecology, ecological areas of life to the full bag of garbage collection, enclosed containers stored the collection rate 100% classification rate of 50%.4、The types and characteristics of the ecological residential (a) the type of ecological residential 1, ecological residential categories : main advocate for the arts in origin, the maximum residential development ecological functional art, and art to such convergence of ecological art to be created as residential to create, whether such residential look from the outside or from within is a piece of art. 2, ecological wisdom categories: ecological wisdom mainly to highlight various features to maximize residential wisdom. Any person living on possible devices capable of providing intelligent services have been placed in the appropriate part, the owner can rely on imagination and simple operation can achieve a special enjoyment. 3, in addition to other types of more! Species, there are eco-religious groups, lived a primitive tribal group, and some of the ecological category, ecological deficit tribunal Residential category. (2) the ecological health of the residential characteristics Ecological residential called "health residential." Not only ecological residential green, and from the planning point of view, the overall ecological area layout, monomer space portfolio, housing construction, natural energy use, energy efficiency measures, green systems and life support services in the design, must be to improve and enhance the ecological environment, the quality of life as a starting point and the goal. Moreover, in actual design, layout on the green level, style and building mutual shine; Focus on different aspects of the complementary integration of plants, such as, inter ordinary plants, flowers and trees to watch, leafy trees, edible fruit trees, medicinal and aromatic plants cultivation; Green throughout the area to play while the other deeper ecological role, such as insulation, wind-proof, dust-proof and anti-noise, the elimination of poison material, adult bacterial virus, or even elimination from the visual sensory and mental fatigue, psychological role. And the housing construction, will consider the ecological and social ecology needs to save energy, to occupants of natural space and interpersonal needs. Ecological residential to health conscious. Real estate not to sell land for the ultimate goal, nor is selling steel, cement house for the ultimate purpose is not to sell the concept and the environment as the ultimate goal, but to create a line with the development of human society and human needs of a healthy and civilized new home for the final goal. It can be said that real estate is selling a lifestyle, a subculture is sold, the sale of a new society and a new trend. Owners as a community, to really enjoy the community healthy and civilized new life, is not only reflected in the design of the real estate business, not only in the real estate area matching hardware facilities, but on community service software, people really enjoy the physical and mental pleasure. This is a healthy and civilized into the 、Ecological design and construction of residential Since China's reform and opening up, economic development has made remarkable achievements, but at the same time was accompanied by a waste of resources and environmental pollution. Since the backward production technologies, our average construction energy is developed 2~3 times, pollution was also very serious, our cities were the World Health Organization as a "serious pollution" in cities. Real estate development and use of a large consumption of resources, produce large quantities of industrial waste. To people hygiene, health, comfortable living, and environmental protection must be put in an important position. (1) The full use of solar energy Solar energy is the most important green energy is inexhaustible, widespread natural energy, and its advantage is extremely rich, clean, safe and cheap. Currently, the use of solar energy in residential areas, there are three main areas : solar water heaters, solar air conditioning and solar cells. According to information on, for the installation of a 300 year by the solar hot water massage central hot water system will require an investment of about 15 million, the annual energy cost about 80,000 yuan, 2a can recover the full investment, and solar water heating systems for 15~20a useful life, then the costs of energy-saving equipment on the high 100~140 million. In recent decades, many countries are active in research, development, the use of solar energy, and achieved encouraging results. The most notable of which Australia and Israel, the prevalence of solar water heaters are 30% and 50%. Our research and development of solar late, and achieved certain results, but only about 6% coverage, and development is uneven and more concentrated in the western region, the highest rate of Yunnan, 10%. My solar abundant sunshine hours for 2500h years, the region accounted for more than 2/3 land area, some areas up to 3000h. This use of solar energy for the development of our country provided a good condition. With scientific and technological progress, the scope will be broader use of solar energy and energy conversion efficiency will be higher. (2) rational use of water resources My country is a lack of water in some places, on the one hand, serious water shortages, on the other hand, wasted. Water is the key measures or "new." Residents primarily drinking water consumption and use, including restaurants use about 5% of total consumption, while the remaining 95% for washing, sewage. In the residential area, according to applications of A, B two water systems. A system specifically for drinking water (including milk, river, village, cooking). The system must be consistent with the water clean water drinking water standards. B system exclusively for the use of water. The water system should be recycling. Household will tell, laundry, water and roofing rain, the ground water within a reservoir, filtration, purification, decontamination of physical, chemical processing, and then imported household "use water" for washing, car washing, forestation, features, flushing, sewage and other use. Water cycle use of the system can save a lot of water. (3) Planning for with the fast-paced economic development, land resources have diminished. Residential areas on the section to the problem, from three aspects 1, the volume of control at a reasonable level, not lower ;2, garage or into the overhead to the construction of three-dimensional multi-storey car park or underground, semi-underground car park ;3, with the section from the energy into two factors, are advised to the construction of multi-storey and high-level incomparable data small apartment, control building door independence households alone villa, particularly yard, beautiful landscape "auspicious treasure-house" should not build luxury villas and private gardens for a handful of people enjoy, and the construction of small parks and other public facilities should be for public enjoyment. (4) strong rectification, the promotion of environmental protection Housing construction and use of the existence of environmental problems. Contaminated environment harms human health, which is well known reason. On the environmental pollution problems in the past only to "waste" (waste, emissions, waste residue) pollution, and now increased pollution and light pollution and sound content. This is the realistic situation. There are problems that electromagnetic pollution. With the improvement of people's living conditions, household appliances and usage is also increasing coverage, electromagnetic pollution has emerged, and the growing tendency. The content of this proposal into water plans and 、Concluding remarks China Environmental Sciences Professor Xia Qing, a real sense of ecological residential areas should be from the design, construction until use, abandoned throughout the life cycle are harmless to the environment, not simply of little grass. Because many of the latest technologies and building materials to be used, in order to build refuse and water treatment devices, the general real estate developers simply can not bear. Now these may be environmental residential advance, but it is our residential development direction.
Urban, city, or town planning is the discipline of land use planning which explores several aspects of the built and social environments of municipalities and communities. Other professions deal in more detail with a smaller scale of development, namely architecture, landscape architecture and urban design. Regional planning deals with a still larger environment, at a less detailed key role of urban planning is urban renewal, and re-generation of inner cities by adapting urban planning methods to existing cities suffering from long-term infrastructural decay.[1]Contents [hide]1 History of Planning 2 The Sustainable City 3 Aspects of Planning Aesthetics Safety Slums Reconstruction and Renewal Transport Suburbanization Natural environment 4 Actors in the planning process 5 Books Seminal to Urban Planning 6 References 7 Further reading 8 See also 9 External links[edit] History of PlanningUrban planning as an organised profession has existed for less than a century, however most settlements and cities have displayed various degrees of forethought and conscious design in their layout and agriculture replaced a nomadic existence, permanent human settlements, and larger settlements began to appear. These early cities became centres for trade, defence, and politics and as centres for distributing the agricultural surplus a settled farming society laid out with forethought and design permeate antiquity. Perhaps the earliest of these were those of the ancient Mesopotamian and Harrapan civilizations of the third century located near the Euphrates and Tigris rivers in modern day Iraq and some ancient cities of the Indus Valley in modern day India are perhaps the earliest examples of deliberately planned and managed cities in history. The streets of these early cities were often paved and laid out at right angles in a grid pattern. There was also with a hierarchy of streets (commercial boulevards to small residential alleyways). In Harrapan settlements, archaeological evidence suggests the houses were laid out to protect from noise, odours, and thieves, and had their own wells, and sanitation. Ancient cities often had drainage, large granaries, and well-developed urban sanitation[2]The Greek Hippodamus (c. 408 BC) is widely considered the father of city planning in the West, for his design of Miletus; Alexander commissioned him to lay out Alexandria, the grandest example of idealized urban planning of the Mediterranean world, where regularity was aided in large part by its level site near a mouth of the ancient Romans used a consolidated scheme for city planning, developed for military defence and civil convenience. The basic plan is a central plaza with city services, surrounded by a compact rectilinear grid of streets and wrapped in a wall for defence. To reduce travel times, two diagonal streets cross the square grid corner-to-corner, passing through the central square. A river usually flows through the city, to provide water and transport, and carry away sewage, even in sieges.[citation needed] Effectively, many European towns still preserve the essence of these schemes, as in idea of rational planning collapsed with the idea of the res publica in the European Early Middle Ages. Round a fortress or fortified abbey or next to a Roman nucleus — sometimes itself abandoned— urban growth occurred "like the annular rings of a tree"[3] whether in an extended village or the center of a larger city. Since the new center was often on high, defensible ground, the city plan took on an organic character, following the irregularities of elevation contours like the shapes that result from agricultural ideal centrally-planned urban space: Sposalizio by Raphael, 1504The ideal city resurfaced in the Early Renaissance in Florence, where the star-shaped city plan was adapted from the new cannon-resistant star fort. The star-shaped fortification had a formative influence on the patterning of Renaissance urban planning: "The Renaissance was hypnotized by one city type which for a century and a half— from Filarete to Scamozzi— was impressed upon utopian schemes: this is the star-shaped city"[4] Radial streets extend outward from a defined center of military, communal or spiritual power. Only in ideal cities did a centrally-planned structure stand at the heart, as in Raphael's Sposalizio of 1504 (illustration); as built, the unique example of a rationally-planned quattrocento new city center, that of Vigevano, 1493-95, resembles a closed space instead, surrounded by arcading. Filarete's ideal city, building on hints in Leone Battista Alberti's De re aedificatoria, was named "Sforzinda" in compliment to his patron; its twelve-pointed shape, circumscribable by a "perfect" Pythagorean figure, the circle, takes no heed of its undulating terrain in Filarete's manuscript.[5]The true heirs of Greek rational planning were the Muslims, who are thought to have originated the idea of formal zoning (see haram and hima and the more general notion of khalifa, or "stewardship" from which they arise),[citation needed] although modern usage in the West largely dates from the ideas of the Congrès Internationaux d'Architecture cities in Central American civilizations also engineered urban planning in their cities including sewage systems and running water. Mexico-Tenochtitlan, was the capital of the Aztec empire, built on an island in Lake Texcoco in what is now the Federal District in central Mexico. At its height, Tenochtitlan was one of the largest cities in the world, with close to 250,000 inhabitants.[citation needed]During the last two centuries in the Western world (Western Europe, North America, Japan and Australasia) planning and architecture can be said to have gone through various stages of general consensus. Firstly there was the industrialised city of the 19th century, where control of building was largely held by businesses and the wealthy elite. Around the turn of the 20th century there began to be a movement for providing people, and factory workers in particular, with healthier environments. The concept of garden cities arose and some model towns were built, such as Letchworth and Welwyn Garden City the world's first garden cities, in Hertfordshire, UK. However, these were principally small scale in size, typically dealing with only a few thousand residents.[6]It wasn't until the 1920s when modernism began to surface. A modernist city was to be a sort of efficient, workable utopia. There were plans for large scale rebuilding of cities, such as Paris in France, though nothing major happened until the devastation caused by the Second World War. After this, some modernist buildings and communities were built. However they were cheaply constructed and became notorious for their social problems.[7]Modernism can be said to have ended in the 1970s when the construction of the cheap, uniform tower blocks ended in many countries, such as Britain and France. Since then many have been demolished and in their way more conventional housing has been built. Rather than making everything uniform and perfect, planning now concentrates on individualism and diversity in society and the economy. This is the post-modernist era.[8][edit] The Sustainable CitySustainable development has become some sort of a 'buzz-word' in the planning industry, with the recognition that present ways of consumption and living have led to problems like the overuse of natural resources, ecosystem destruction, pollution, growing inequality in cities, the degradation of human living conditions and human-induced climate change. Planners have, as a result, taken to advocating for the development of sustainable cities.[9]However, the notion of sustainable development can be considered as rather recent and evolving, with many questions surrounding this concept.[10] That said, it is often not difficult to recognise what are 'unsustainable' forms of lifestyles, and urban planning is recognised to play a crucial position in the development of sustainable Wheeler, in his 1998 article, suggests a definition for sustainable urban development to be as "development that improves the long-term social and ecological health of cities and towns."[11]He goes on to suggest a framework that might help all to better understand what a 'sustainable' city might look like. These include compact, efficient land use; less automobile use yet with better access; efficient resource use, less pollution and waste; the restoration of natural systems; good housing and living environments; a healthy social ecology; sustainable economics; community participation and involvement; and preservation of local culture and wisdom.[12]The difficult challenge facing planners comes with the implementation of sustainability visions, policy and programmes, and in the midst of doing so, the need to modify institutions to achieve these goals. This is still being worked out by urban planners.[edit] Aspects of Planning[edit] AestheticsThis article does not cite any references or help improve this article by adding citations to reliable sources.

Towns and cities have been planned with aesthetics in mind, here in Bath (England), 18th century private sector development was designed to appear developed countries there has been a backlash against excessive man-made clutter in the environment, such as signposts, signs, and hoardings.[13] Other issues that generate strong debate amongst urban designers are tensions between peripheral growth, increased housing density and planned new settlements. There are also unending debates about the benefits of mixing tenures and land uses, versus the benefits of distinguishing geographic zones where different uses predominate.[14]Successful urban planning considers character, of "home" and "sense of place", local identity, respect for natural, artistic and historic heritage, an understanding of the "urban grain" or "townscape," pedestrians and other modes of traffic, utilities and natural hazards, such as flood argue that the medieval piazza and arcade are the most widely appreciated elements of successful urban design, as demonstrated by the Italian cities of Siena and Bologna[citation needed].While it is rare that cities are planned from scratch, planners are important in managing the growth of cities, applying tools like zoning to manage the uses of land, and growth management to manage the pace of development. When examined historically, many of the cities now thought to be most beautiful are the result of dense, long lasting systems of prohibitions and guidance about building sizes, uses and features. These allowed substantial freedoms, yet enforce styles, safety, and often materials in practical ways. Many conventional planning techniques are being repackaged using the contemporary term, smart are some cities that have been planned from conception, and while the results often don't turn out quite as planned, evidence of the initial plan often remains. (See List of planned cities)[edit] Safety The medieval walled city of Carcassonne in France is built upon high ground to provide maximum protection from within the Middle East, Europe and the rest of the Old World settlements were located on higher ground (for defense) and close to fresh water sources[citation needed]. Cities have often grown onto coastal and flood plains at risk of floods and storm surges. Urban planners must consider these threats. If the dangers can be localised then the affected regions can be made into parkland or Greenbelt, often with the added benefit of open space weather, flood, or other emergencies can often be greatly mitigated with secure emergency evacuation routes and emergency operations centres. These are relatively inexpensive and unintrusive, and many consider them a reasonable precaution for any urban space. Many cities will also have planned, built safety features, such as levees, retaining walls, and recent years, practitioners have also been expected to maximize the accessibility of an area to people with different abilities, practicing the notion of "inclusive design," to anticipate criminal behaviour and consequently to "design-out crime" and to consider "traffic calming" or "pedestrianisation" as ways of making urban life more planning tries to control criminality with structures designed from theories such as socio-architecture or environmental determinism. These theories say that an urban environment can influence individuals' obedience to social rules. The theories often say that psychological pressure develops in more densely developed, unadorned areas. This stress causes some crimes and some use of illegal drugs. The antidote is usually more individual space and better, more beautiful design in place of Newman’s defensible space theory cites the modernist housing projects of the 1960s as an example of environmental determinism, where large blocks of flats are surrounded by shared and disassociated public areas, which are hard for residents to identify with. As those on lower incomes cannot hire others to maintain public space such as security guards or grounds keepers, and because no individual feels personally responsible, there was a general deterioration of public space leading to a sense of alienation and social disorder SourceJane Jacobs is another notable environmental determinist and is associated with the "eyes on the street" concept. By improving ‘natural surveillance’ of shared land and facilities of nearby residents by literally increasing the number of people who can see it, and increasing the familiarity of residents, as a collective, residents can more easily detect undesirable or criminal "broken-windows" theory argues that small indicators of neglect, such as broken windows and unkempt lawns, promote a feeling that an area is in a state of decay. Anticipating decay, people likewise fail to maintain their own properties. The theory suggests that abandonment causes crime, rather than crime causing abandonment[citation needed].Some planning methods might help an elite group to control ordinary citizens. Haussmann's renovation of Paris created a system of wide boulevards which prevented the construction of barricades in the streets and eased the movement of military troops. In Rome (Italy), the Fascists in the 1930s created ex novo many new suburbs in order to concentrate criminals and poorer classes away from the elegant town. Robert Moses' developments in New York were intended to limit the effectiveness of public transit; bridges over parkways were built too low to accommodate buses, in order to restrict access to the beach by racial minorities and the social theories point out that in Britain and most countries since the 18th century, the transformation of societies from rural agriculture to industry caused a difficult adaptation to urban living. These theories emphasize that many planning policies ignore personal tensions, forcing individuals to live in a condition of perpetual extraneity to their cities. Many people therefore lack the comfort of feeling "at home" when at home. Often these theorists seek a reconsideration of commonly used "standards" that rationalize the outcomes of a free (relatively unregulated) market.[edit] SlumsMain article: Slums The rapid urbanization of the last century has resulted in a signifcant amount of slum habitation in the major cities of the world, particularly in the Third World. There is significant demand for planning resources and strategies to address the issues that arise from slum development, and many planning theorists and practitioners are calling for increased attention and resources in this area, particularly the Commonwealth Association of Planners.[15]The issue of slum habitation has often been resolved via a simple policy of clearance, however more creative solutions are beginning to emerge such as Nairobi's "Camp of Fire" program, where established slum-dwellers have promised to build proper houses, schools, and community centers without any government money, in return for land they have been illegally squatting on for 30 years. The "Camp of Fire" program is one of many similar projects initiated by Slum Dwellers International, which has programs in Africa, Asia, and South America.[16][edit] Reconstruction and RenewalMain article: Urban Renewal The overall area plan for the reconstruction of Kabul's Old City area, the proposed Kabul - City of Light devastated by war or invasion represent a unique challenge to urban planners: the area of development is not one for simple modification, nor is it a "blank slate". Buildings, roads, services and basic infrastructure like power, water and sewerage are often severely compromised and need to be evaluated to determine what, if anything, can be salvaged for re-incorporation. There is also the problem of population; more often than not, people are also still living in these areas, displaced but not removed, and their issues need to be addressed. Historic areas and religious or social centers also need to be preserved and re-integrated into the new city plan. A prime example of this is the capital city of Kabul, Afghanistan, which after decades of civil war and occupation has regions that have literally been reduced to rubble. Despite this, the indigenous population continues to live in the area, constructing makeshift homes and shops out of whatever can be salvaged. Any reconstruction plan proposed, such as Hisham Ashkouri's City of Light Development, needs to be sensitive to the needs of this community and its existing culture, businesses and Reconstruction Development plans must also work with government agencies as well as private interests to develop workable designs.[edit] TransportMain article: Transportation Planning Very densely built-up areas require high capacity urban transit, urban planners must consider these factors in long term plans. Although an important factor, there is a complex relationship between urban densities and car is a direct, well-researched connection between the density of an urban environment, and the need to travel within it[citation needed]. Good quality transport is often followed by development. Development beyond a certain density can quickly overcrowd transport[citation needed].Good planning attempts to place higher densities of jobs or residents near high-volume transportation. For example, some cities permit commerce and multi-story apartment buildings only within one block of train stations and four-lane boulevards, and accept single-family dwellings and parks further away[citation needed].Densities can be measured in several ways[citation needed]. A common method, used is the Floor area ratio, using the floor area of buildings divided by the land area. Ratios below could be considered low density, and plot ratios above five very high density. Most exurbs are below two, while most city centres are well above five. Walk-up apartments with basement garages can easily achieve a density of three. Skyscrapers easily achieve densities of thirty or authorities may try to encourage lower densities to reduce infrastructure costs, though some observers note that low densities may not accommodate enough population to provi
