摘要

In this paper,the research background,research ideas,main work completed and research significance of "land subsidence survey and monitoring in Hebei Plain" are introduced,while the groundwater and ground fissure conditions of Hebei Plain,characteristics of the land subsidence monitoring network are summed up. The distribution rule,influencing factors,formation mechanism and harm characteristics of land subsidence are analyzed,and development trend of land subsidence in Cangzhou City,as the center of land subsidence in Hebei Plain,is forecasted also. In addition,reasonable countermeasures are put forward according to current situation of land subsidence.%介绍了"河北平原地面沉降调查与监测"项目的研究背景、研究思路、完成的主要工作量及研究的意义,并总结了河北平原地下水状况、地裂缝状况及地面沉降监测网特点,分析研究了地面沉降的分布规律、影响因素、成因机制及危害特征,预测了河北平原地面沉降中心沧州市的地面沉降发展趋势,针对地面沉降现状,提出了合理的防治对策.
