摘要
海绵城市建设通过改变流域下垫面条件来蓄滞雨洪,在减少城市雨水地表径流量、缓解城市内涝、补给地下水方面发挥了重要作用。在此过程中,增加流域雨水下渗量、利用雨水回补地下水是海绵城市建设的重要手段,也是雨水资源利用和缓解城市水资源短缺的重要举措。针对当前海绵城市建设中地下水回补量化的难题,本文对国内外适用于海绵城市建设中地下水补给量的计算方法进行了概述,分别介绍了各方法的基本原理、优缺点及适用情况,旨在为我国海绵城市建设地下水补给的效果评估提供参考。
By changing the conditions of underlying surface to delay rainfall convergence rate and accumulate rainwater resources,sponge city construction plays a key role in reducing urban rainwater surface runoff and mitigating urban internal sputum.During sponge city construction,increasing rainwater infiltration volume and using rainwater to replenish groundwater are important methods of improving rainwater resource utilization and mitigating urban water shortage.In view of the problems in quantification of groundwater recharge in sponge city construction,we summarized the quantification methods and introduced the basic principles,advantages,disadvantages and the application of each method to provide a reference for evaluating the effect of groundwater recharge in sponge city construction in China.
