摘　　要：第四届地面沉降国际讨论会及我国“八五”科技攻关成果表明，我国地面沉降研究及防治工作，由于引进系统思维方式、非线性科学的新理论与方法及计算机技术，融地球科学、环境科学和社会科学为一体进行综合研究，成果显著，目前已进入以数学模型预测为主的动态微量控沉阶段。这要求我们加深沉降机理研究。抽汲地下水形成的地面沉降研究的核心与难点是粘性土中孔隙水运移问题，它也是土体环境地质和外动力地质灾害研究的前缘热点，应引起人们的高度重视。The 4th international Conference of Land Subsidence and the results of scientific research in the Eighth Five-Year Plan of China show that the research on land subsidence and its control in China has made remarkable progress due to the introduction of the theory of systems and nonlinear science as well as the use of modern computer technology and the comprehensive consideration of geological. environmental and social sciences.At present,the mathematical model used in land subsidence research is the predominantway of prediction of the dynamic controlling slight land subsidence. The key to the subsidence mechanism lies in the porous water migration from the clayey soils. It is the hotsubject of soil environmental geology and exogenous geological hazard. and is the pointthat one should draw attention to.
