北京市应急水源工程续采可持续利用研究

由于南水北调水源推迟进京,需要在地下水资源可持续利用的条件下对已有的应急水源地进行续采来保障北京的供水安全。运用地下水数值模拟技术对北京市昌平区马池口应急水源地在不同应急续采方案下的地下水位变化趋势进行模拟预测,为应急水源地的科学续采提供技术支持。研究表明:马池口应急续采造成区域地下水位持续下降,停采后地下水位逐渐恢复;南水北调水源进京前,马池口应急水源工程以12.5万m3/d续采2 a、停采2 a、再续采1 a的方案为同时满足最大应急开采又保障应急水源工程可持续利用的方案。因此,马池口应急水源地在南水北调水源进京前能续采3 a。

Study on sustainable exploitation of groundwater emergency water-supply field under emergency situation for Beijing City

As the South-to-North Water Diversion to Beijing is postponed,the emergency underground water sources are needed to continue being exploited to guarantee the safety of water supply for Beijing City under the condition of sustainable utilization of underground water.In order to provide technological support for scientific exploitation of emergency underground water sources,by using groundwater numerical model,we simulate and predict the underground water level variation tendency of Machikou emergency undergr...
