摘　　要：通过改善下垫面条件增加地表雨水下渗补给地下水是韧性城市建设的重要目标,也是雨水资源化利用和缓解城市水资源短缺的重要举措。从国内外城市雨水补给地下水利用切入,分别从相关政策法规、补给方式、水质问题和数值模拟等方面,综合评述了现阶段雨水补给地下水利用面临的挑战和不足。提出了该领域未来的研究方向:解决人工回灌技术中的堵塞问题,如何精确计算人工滞留渗透措施的地下水实际补给量。城市雨水径流补给地下水过程中要加强源头削峰减污、过程控制和末端治理。未来地下水补给领域数值模拟应注重水文模型和地下水模型的数值模拟耦合,大力发展区域和场地耦合模型,精细刻画雨水径流补给地下水过程。中国雨水利用的政策法规体系还不完善,建议推动雨水利用立法,以期为进一步雨水集蓄利用及城市雨水补充地下水相关研究和管理提供方向与参考。Increasing surface rainwater infiltration to recharge groundwater by improving the condition of the underlying surface is an important goal of resilient city construction,as well as a vital initiative for utilizing rainwater resources and alleviating urban water shortage.This study examined the utilization of groundwater supplemented by urban rainwater in China and abroad and reviewed the challenges and shortcomings faced by the utilization of groundwater supplemented by urban rainwater at the present stage from the aspects of recharge methods,water quality problems,numerical simulation,and relevant policies and regulations.The study proposed future research directions in this area,including solving clogging problems in artificial recharge techniques and accurately calculating the actual groundwater recharge from artificial retention infiltration measures.As groundwater is supplemented by urban rainwater runoff,it is necessary to strengthen peak shaving and pollution reduction at the source,process control,and end-of-pipe treatment.In the future,the numerical simulation in the field of groundwater recharge should focus on the numerical simulation coupling of hydrological models and groundwater models,vigorously develop regional and site coupling models,and finely delineate the process of groundwater supplemented by rainwater runoff.China's rainwater utilization policies and regulation system have room for improvement,so it is recommended to promote rainwater utilization legislation,so as to provide direction and reference for further research and management related to rainwater gathering and utilization,as well as groundwater supplemented by urban rainwater.
