摘　　要：低影响开发(LID)作为海绵城市理念的核心之一,其目的是最小化土地利用活动对水资源的影响,减少城市对传统水资源的依赖,从而缓解水资源压力。以广州庙头涌排涝片为研究区域,基于SWMM模型,模拟透水铺装、雨水花园和绿色屋顶三种LID设施组合的水文及水环境过程,并分析了LID设施空间分布变化对城市水文与水环境效应的影响。结果表明,单一LID设施中对城市水文效应控制最好的是透水铺装,对城市水环境效应控制最好的是雨水花园;当组合LID设施进行布设时,透水铺装+绿色屋顶+雨水花园(S7)对水文及水环境效应削减效果最好,对径流量的削减效果优于洪峰流量;LID设施布设在上游对径流量和污染物总量的削减效果最好,可以有效降低洪涝风险,改善城市水环境。As one of the core concepts of sponge city, low impact development(LID) aims to minimize the impact of land use on water resources, reduce the city's dependence on traditional water resources, and relieve the pressure on water resources. Based on the SWMM model, the hydrological and water environment processes of the combination of three LID facilities, namely permeable pavement, rain garden and green roof, were simulated in Miaotou Chung flood drainage area in Guangzhou, and the effects of spatial distribution changes of LID facilities on urban hydrology and water environment were analyzed. The results show that in a single LID facility, the best control of urban hydrological effect is permeable pavement, and the best control of urban water environment effect is rain garden. When the combination of LID facilities is deployed, permeable pavement + green roof + rain garden(S7) has the best effect on reducing hydrology and water environment effects, and the reduction effect on runoff is better than the peak flood flow. The layout of LID facilities in the upstream has the best effect on reducing the runoff and the total amount of pollutants, which can effectively reduce the risk of flooding and improve the urban water environment.
