统计学发表过的学术论文

如硕士论文（1991年）系统研究了中国暖温带变性土（黑粘土类）的形成和分类。博士论文（1995年）研究了华北平原冲积土壤的质地层次空间分异特征及对农田水平衡的影响。1998年主持国家自然科学基金面上项目“冲积土壤质地层次空间变化的模拟研究”。自1999年以来在开展离散空间变量的多维马尔可夫链模拟研究中，通过长期不懈的努力，在艰难处境中与张传荣教授合作逐步提出了多维马尔可夫链模拟的一系列理论、方法和技术，构建了“马尔可夫链地统计学”，成为地统计学和地球空间分析上的一个独立的理论方法体系。另外在网络GIS、遥感图像处理、土壤空间变异描述模拟和区域环境模拟等方面也取得了重要进展。马尔可夫链地统计学(Markov chain geostatistics)的主要论文于2007年发表于数学地质（Math. Geol.）和美国土壤学会会刊(Soil Sci. Soc. Am. J.)等国际刊物上，主要内容包括“马链随机域”(Markov chain random field)理论及有关模拟算法和“转移概率函数”(Transiogram)理论及有关联合拟合方法。有关理论分别从数学推导和实例验证上得到了证明。该研究被认为是“对地统计学和地球空间分析的重大贡献”，提出了新的概念、理论和方法，开辟了空间统计学研究上的一个新领域。在国际数学地质、地理学、土壤学和水文学等学界引起很大关注。在地理信息、土壤、数学地质、环境统计和遥感等领域国际刊物上发表了一系列重要学术论文。该研究到目前为止已发表有关国际刊物论文17篇，建立起了一个理论方法体系框架，未来的扩展和应用仍将是一个长期的工作。自1992年以来，李卫东博士共发表学术论文近70篇，其中第一作者论文40余篇，英文论文40余篇，国际刊物论文30余篇。他于2007年春应邀编写国际人文地理百科全书马尔可夫链分析一文，在2008年和2009年多次被提名到美洲名人录。 1.Zhang, C., T.
