北京西郊地处永定河冲洪积扇顶部，地下水丰富，然而多年来的过量开采使得该区地下水位下降幅度较大。南水北调水进京后，地下水开采量将减少，因此需要开展恢复适宜水位研究，控制地下水位恢复。根据研究区水文地质条件，通过砂石坑、地下建筑、垃圾填埋场调查进行工程与环境限制水位的研究，对比历史流场后确定1983年枯水期流场为地下水位恢复的适宜水位。

The western part of Beijing is located in the toparea of the Yongding Riveral uvial fan, where the storage of groundwater is abundant. Groundwater level declined rapidly in recent years due to over-exploitation. The South-to-North Water Transfer Project into Beijing can decrease groundwater extraction, so it is necessary to study the suitable groundwater recovery level and to control its recover-y rate. Based on the hydrogeological conditions of the study area, the engineering and environmental limited groundwater level was stud-ied through the investigations of gravel pit, underground construction, and landfil site. Compared with the historical flowfield, the suit-able groundwater recovery level was determined to be the flowfield of the dry season in 1983.
