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

当前,城市设计已成为规划界、建筑界的热点研究领域。在理论上可谓百家争鸣,呈现出从未有过的繁荣局面; 在实践上,从南到北,全国上下,各种各样的“城市设计”项目如雨后春笋,特别是一些重大的国际竞赛、招标项目,更是把“城市设计”推上了一个新的高潮,使 “城市设计”正悄然成为一种时尚,城市设计的地位也日益提高。又由于城市设计自身兼有理论形态与实践形态的双重属性,并在长期的探索中形成了一定理论与方法,因此,城市设计“独立”的呼声日渐高涨。 人们经常可以看到类似“城市设计是一门独立的学科”的说法,在学科体系中把城市设计与城市规划并列等同; 同时,大量以“X X X城市设计”命名的工程项目及设计成果不断涌现。这种现象的出现,一方面说明重视城市设计的思想正日益深人人心,这对提高我国城市规划设计质量、改善城市空间环境无疑是十分有益的;然而另一方面,如果缺乏深人的思考和研究,片面强调城市设计独立于城市规划之外,不但不利城市规划学科体系和理论体系的完善,还可能导致城市设计流于表面化和形式化,反而不利城市设计积极作用的发挥。因此,必须明确城市设计在城市规划学科体系中的地位与作用,理顺其与城市规划的关系,才能切实达到指导城市建设的目的。 应该说,城市设计与城市规划一直都有着难舍难分的渊源关系。 从历史发展看,工业革命以前及其早期的很多城市规划理论与实践,用今天的眼光来看就是城市设计活动,可见,对于那一时期而言,城市规划与城市设计是同一行为的不同表述而已;即使是现代城市设计的产生,也与城市规划难分你我。现代城市设计论的倡导者沙里宁最初建议:“。,。…为了分析中避免引起误解,谈到城市的三维空间概念时,就避免使用‘规划’改用‘设计’这个名词……一,在不涉及到所讨论的问题时,同意接受‘规划’这个通称。” 由此可知,城市设计最初是承担了城市规划中某一领域(三维空间)或某一部分的工作,并为了把该部分工作加以强调而作的用词上的规定,目的是为了提起人们对该部分工作的重视。这主要是因为随着社会的发展,现代城市规划与建筑设计的分工,引起了城市空间设计的削弱,导致城市空间整体环境质量逐渐下降。人们为克服这一弊端,提出了城市设计的概念,使城市设计工作得到了恢复与发展。1965年美国建筑师协会出版的《城市设计—城镇建筑》一书中也提到,今日我们不得不使用城市设计(UrbanDesign)这个词汇, (与传统的城市设计Civ-ic Design相区别—笔者注),但“城市设计概念的建立,并非要去创造一个新的分离的领域,而是要防止这一基本的环境问题被忽视或丢弃。”可见,城市设计概念的提出,不是为了创建一个全新的学科,而是为了唤祝人们对环谙问颗的羊汁,为了恢复城市规划本身具有却被长期忽视的塑造、改善城市空间环境质量的职能,从而使城市规划更好、更全面地为城市建设服务。 从实际的操作层面上看,城市设计与城市规划也是紧密结合、密不可分的。 城市三维空间景观的塑造与城市平面布局是一种互为条件、相互制约的关系。城市规划在涉及城市的用地布局、路网结构、市政设施等诸方面的同时,必然包含了对城市空间特征塑造的思考,没有“纯二维”的规划,而且规划的思想观念和意图也必须最终投映在土地和空间中才能得以实现。城市设计和城市规划所要研究的对象都是人们所处的城市,只是侧重点有所不同,它们都以创造一种良好的、有序的生产、生活环境为目的,都要综合协调各项城市功能,安排城市各项用地,组织好交通和安排好各类工程设施,都要研究城市的社会发展,考虑城市的历史文脉等。 可见,它们之间交叉、重叠的领域涵盖了城市建设系统各个方面,两者统一于一个完整的规划过程之中。规划的平面布局图,也是城市设计进行城市三维空间环境塑造的基础依据和前提; 另一方面,对城市空问的塑造与安排,又可反馈回来对平面布局进行完善、补充和调整,从而使两者都趋于更加合理化。反之,城市设计与城市规划脱节,其交又的部分必不能取得统一,出现设计和规划之间改动很大的现象,造成时间、人力、物力、财力多方面的浪费;如果不进行改动,两个不同的方案对于同一城市或同一地块而言在实际中根本无法操作实施,规划设计的方案只能落个“图上画画、墙上挂挂”的结果。当前很多地方都是在还没有进行规划之前,就委托进行“城市设计”,这种没有规划原则指导的“城市设计”最终也只能停留在漂亮的模型和图纸上,很难说有多少现实意义。 另外,从我国的城市规划的实践来看,城市规划和城市设计也一直是融合在一起、互相渗透、密不可分的。我国城市规划的发展可概括为: 本世纪初学欧美,50年代学前苏联,80年代以来学欧美与建构我国城市规划理论并存(60^-70年代断层,无规划)。无论哪个时期,在规划程序上始终以总体规划设计(含分区规划)和详细规划设计进行阶段划分,如果“设计”观念不在全过程体现就无法达到整体效果上的完美。而且,在我国以往的规划实践中,普遍存在着注重物质形态规划、对可行性分析、经济与社会发展方面的研究相对薄弱的问题。对成果的评价也往往是认为图纸画得越漂亮,设计水平就越高;我国现行的规划教育体制仍未能突破形态规划的传统,使得学生对“形体”、“造型”的设计产生偏爱,而缺乏对理论研究的关注和热情。 因此,我国的城市规划无论从实践发展,还是从对规划的认识、规划的过程以及教育体制上,在对形体方面的关注不是提得不够,而是提得过多了,这与西方国家的情况是不一样的,有识之士早就开始呼吁:“超越形态规划”、“少些表现、多些研究”,在这种情况下,如果片面强调城市设计的独立性,很可能是为形体规划论打起了一把保护伞,使我们又回到只注重物质形态规划的老路上去,这一点应引起足够的重视。 “城市规划设计”一词反映了我国城市规划学科发展的历程,规划和设计相结合,反映了我国城市规划工作的特点和实际。对城市功能结构的合理安排布局与对城市空间环境的塑造,是一个完整的城市规划过程中不密不可分的指导城市建设的两个方面,若人为地将其分开,必然产生众多的、难以解决的矛盾。 城市设计只有与城市规划相结合,走一体化的道路,才能充分发挥其空间景观环境塑造的职能,才能真正实现设计价值观从以规划师为主体向以使用者为主体的转变。城市规划应将城市设计作为自己学科领域的一个组成部分。将城市设计纳人统一的城市规划过程,不仅因为它们所处理的内容和对象相接近或者衔接得非常紧密而无法明确划分开来,而且还完善了城市规划对城市社会整体的把握,同时也符合我国城市规划发展的实际。 即使在西方,60 年代以后城市设计的发展也并不是废弃了城市规划,而恰恰是城市规划发展的进一步深化。城市规划工作的重点向两个方向转移:一个是以Zoning为代表的法规文本体系的制定和执行,另一个就是以人为中心,通过城市空间环境塑造提高人们生活空间的环境质量和生活质量的城市设计。只有在这样的背景下,城市设计才有可能获得全面的发展。因此可以说,城市设计与城市规划是一个完整的城市规划过程中紧密结合的两个方面,两者互为条件、相互依存、相辅相承,共同为城市建设服务。只有走城市设计和城市规划一体化的道路,才能兼顾各方面的效益,使城市建设大系统达到最优化。

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 efforts.3、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 dB.5, 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 home.5、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 measures.6、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.
