摘　　要：稳定的水源对城市发展十分重要,南水北调中线工程启用后,可将盈余来水人工回灌到地下水库中进行存储,以提高北京市供水保证程度.南水北调中线工程于2014年末对北京供水,并在未来五年间通过潮白河河道补给地下水.根据密云调蓄工程已批复的设计方案,每年的回补时段为3月1日至12月15日,共计290天,补水量为1～3亿m3/a,自牛栏山橡胶坝向上游回水约12 km,形成水面约480 hm2.通过地下水模拟软件GMS建立受水区地下水流模型,据此预测评价了3种补水方案对研究区地下水位及地下水开采能力的影响.Stable water sources are important for urban development.After the operation of the South-to-North Water Diversion Project,the redundant water can be recharged into underground reservoirs artificially to improve the water supply guaranteed rate in Beijing.From the end of 2014,the Middle Route of the South-to-North Water Diversion Project supplies water to Beijing and recharges groundwater through the Chaobai River in the next five years.According to the approved design scheme of the Miyun Storage Project,the annual recharge period is from March 1st to December 15th,and recharge rate is about 100 to 300 million m3/a.The backwater is about 12 km upstream of the Niulanshan rubber dam,forming a surface of about 480 hectares.A numerical model of groundwater flow was developed using GMS to evaluate the impacts of three recharge schemes on the groundwater level and production capacity in the study area
