摘 要:A series of environmental—geological problems have been caused by over-exploitation of deep groundwater(i.e.,confined aquifer water) in the North China *** order to better understand the status of deep groundwater over-exploitation and the resultant environmental—geological problems on a regional scale,the over-exploitation of groundwater has been assessed by way of the groundwater exploitation potential coefficient(i.e.,the ratio of exploitable amount of deep groundwater to current exploitation), cumulative land subsidence,and long-term average lowering rate of the groundwater *** is a good correlation among the results calculated by the different *** a regional scale,deep groundwater has been over-exploited and there is no further exploitation potential under the current *** groundwater exploitation degree index takes the exploitation in 2003 as the reference for the calculations, so the results mainly reflect the degree of current groundwater *** results of over-exploitation of deep groundwater obtained by land subsidence data and long-term average rate of depression of the water table mainly reflect environmental—geological problems caused by exploitation of deep groundwater.
