摘　　要：针对华北平原农业灌溉地下水超采的问题,以房山节水示范区为例,采用机井取水量定额管理的方法,基于水文地质模型软件GMS,对示范区地下水位进行模拟研究。结果表明:取水量定额管理后,示范区2020年模拟的地下水位比现状回升了3.34m,比按现状取水量模拟的地下水位多回升了1.49m。机井取水量定额管理可以提高地下水位的回升力度,是实现区域地下水采补平衡的有效措施。Aiming at the problem of groundwater overexploitation in North China Plain,a case of water-saving demonstration area in Fangshan,where the situation of groundwater overexploitation is serious,is investigated using the method of the water supply quota management of well.A groundwater simulation software GMS was used to simulate groundwater in water-saving demonstration area.The results showed that:After the water supply quota management,the simulated groundwater level in the demonstration area in 2020 would be recovered to 3.34 m,which is 1.49 mhigher than the current management simulated groundwater level.Quota management can improve the strength of underground water level recovery and is one of the effective measures of groundwater dynamic balance.
