太湖流域苏锡常地区地面沉降若干问题探析

地面沉降是我国和世界上许多城市出现的重要地质灾害之一，它是由多种因素引发的地表海拔缓慢降低现象。苏锡常地区位于太湖流域的核心地带，是我国经济最发达的地区之一。但是，随着经济的持续发展、人口的急剧增加、城镇化进程的不断加快，地下水开采日益强烈，已引发大范围严重的地面沉降，对当地生存和发展环境构成极大威胁。对苏锡常地区地面沉降现状、成因及危害的分析表明：要系统解决该地区地面沉降问题，必须从经济社会发展需要和生态环境保护的角度出发，综合运用法律、经济、技术、行政等手段，坚持走新型工业化道路，加快经济结构调整，坚决禁止过度开采地下水，优化地表水和地下水的使用与管理。

ANALYSIS ON PROBLEMS AND COUNTERMEASURES OF LAND-SURFACE SUBSIDENCE IN TAILAKE BASIN

Land-surface subsidence is one of major geological calamities in many cities around the world. It is a phenomenon caused by many factors that surface altitude lowers slowly. Three cities:Suzhou,Wuxi and Changzhou(SWC) lie in the core of Tailake basin which is one of the most developed area in China. Due to continuous economic development, rapid increase of population and accelerated urbanization, especially groundwater withdrawal, large-scale and serious surface subsidence occurs, and threatens sustainable survival and development in these cities. On the basis of investigating surface subsidence and its effect on the cities ,this article analyzes its forming and predicts the consequence. From the need of economical and social development and ecological environment protection, and by means of law, economy, technology and management, it puts forward suggestions and countermeasures for controlling surface subsidence through taking the path of new-type industrialization, accelerating the pace of economic restructure, prohibiting over-exploitation of groundwater and economizing the use of groundwater.
