| 摘 要： | 根据特征致灾因子的差异，将中国城市灾害类型大体上划分为沿海台风暴雨洪涝地面沉降型、北方干旱缺水风沙地面沉降型和南方洪涝渍害地面沉陷塌陷型等三大类型区。分别用上海、北京、武汉作为三种案例地区，讨论了以上三种城市灾害类型区的主要灾害及其地学背景。指出除了自然地理的因素外，人类在城市灾害致灾因素中也通过开采地下水、设计防洪排涝设施等行为表现出一定程度的作用.

| Abstract: | According to an analysis of differences among disaster-gnerating elements,the authors regionalized China's urban disasters into three basic types, (a) the Coastal (withtyphoon, storm, flood and waterlogging and ground subsidence), (b) the Northern (witharid, wind blowing dust, sand storm and ground subsidence), and (c) the Southern (withflood, waterlogging and ground sinking). Taking Shanghai, Beijing and Wuhan as threecases, the authors analyzed each city's main physical disasters and their geographicalbackgrounds and human impacts on the occurrence of these disasters by activities such asunderground water extraction and flood prevention. |
