| 摘 要： | 为探究海绵城市建设对区域地下水资源的补给效应,以某海绵城市建设实验区为例,采用Visual MODFlow软件分别对海绵城市不同建设方案条件下的地下水水位动态进行模拟预测。结果表明:城市建设增大了地表不透水面积,使地下水补给量减少,导致区域地下水水位普遍下降,且下降幅度受下垫面变化特征的影响;海绵城市建设对地下水资源的补给作用与低影响开发工程设施的类型有关,也与其规模有关,仅当海绵城市建设达到一定规模之后才能对区域地下水资源产生较为明显的补给效应。

| Abstract: | In order to study the recharge effect of sponge city construction on regional groundwater resources, taking an experimental sponge city construction area as an example, the groundwater level dynamics of sponge city under different construction schemes were simulated and predicted by using Visual MODFlow software. The results show that urban construction enlarges the impervious surface area and reduces the groundwater recharge, which leads to the general decline of regional groundwater level, and the extent of decline is affected by the characteristics of underlying surface changes. The recharge effect of sponge city construction on groundwater resources is related to the type and scale of low impact development engineering facilities. Only when the construction of sponge city reaches a certain scale can the recharge effect on regional groundwater resources be more obvious. |
