GROUNDWATER LEVEL VARIATION AND ITS IMPACT ON LAND SUBSIDENCE IN THE EASTERN AREA OF BEIJING
英文摘要
Based on a lot of historical monitored data of groundwater and land subsidence,a detailed analysis was performed on the evolutional characteristics of the quaternary aquifer and the relationship between groundwater and the land subsidence in the eastern area of Beijing.The results indicated that the third and the fourth aquifer group were the main groundwater exploitation layers,and they were in a serious over-exploitation state,since 1998.Currently the groundwater funnel is located in the region between Tongzhou and Guanzhuang.Moreover,the land subsidence was found to be closely correlated to the variation of groundwater level,groundwater withdrawal intensity and depth.The excessive withdrawal of groundwater is the major cause of land subsidence.Finally,due to the groundwater exploitation depth change,land subsidence is gradually developing to deep strata,and the amount of compression in the deep strata is also increasing gradually.
