南水北调引水进京后北京市地下水环境预测

本文通过对受水区的地下水水位、水质变化预测,分析了北京市区的地下水环境变化情况,提出了调水工程实施后将会产生的主要环境地质问题。并结合地下水环境修复、生态恢复、地质环境问题防治等实际需要,进行了地下水停采方案的分析,为北京市未来水资源调配、地下水环境保护、城市规划修编提供依据。

Prediction of groundwater environment in Beijing after water entering the capital by the South-North Water Diversion

In this paper, changes in groundwater environment in the urban area of Beijing after water entering the capital by the South-North Water Diversion are analyzed on the basis of observations of the changes in the dynamic equilibrium of current groundwater resource and the prediction of groundwater levels, water quality variations. Main environmental geological problems appearing after implementing the diversion project are also presented in this paper. With a combination of groundwater environment repairing, ecological recovering, and prevention of geological environmental problems, the schemes of stopping exploitation of groundwater are analyzed. The results provide supports of water resources allocation, groundwater environment protection and repairing and arrangement of urban planning in Beijing in the future.
