摘　　要：为了探索下凹绿地和雨水花园在工程实践中的对比优选,详细介绍分析了下凹绿地和雨水花园这两种低影响开发设施。选取桐庐县某小区,通过构建SWMM模型,模拟基础组合、基础+下凹绿地、基础+雨水花园3种LID布设方案在1年一遇、2年一遇、5年一遇重现期暴雨时的出水口径流过程及各污染物负荷总量,并选用层次分析法评价了下凹绿地和雨水花园的综合效能。结果表明,下凹绿地和雨水花园对径流和水质均有一定的削减作用,且雨水花园作用效果更显著,层次分析评价出雨水花园综合效能更优。In order to explore the comparative selection of sunken lawn and rain garden in the engineering practice,the two low-impact development facilities of sunken lawn and rain garden is analyzed in detail. A community in Tonglu County is selected to build SWMM model to simulate the runoff process and the total contamination load under LID basic combination,basis add sunken lawn and basis add rain garden in the case of the storm occurs every year,every two years and every five years. And the AHP method is used to evaluate the comprehensive performance of sunken lawn and rain garden. The results show that sunken lawn and rain garden have a certain effect on runoff and water quality,and the effect of rain garden is more significant. The AHP evaluation indicates that rain garden has better overall performance.
