摘　　要：为研究低影响开发措施(low impact development, LID)对城市雨水径流的影响,在青岛市某区域现状开发的基础上,提出了4种LID设施布设方案,利用某暴雨排水及低影响开发模拟系统(HYSWMM)模拟分析了5种暴雨重现期下,各方案对地表径流及面源污染的控制效果,并利用生命周期成本进行了方案成本效益分析。结果表明:LID设施对研究区域的地表径流和面源污染削减有显著贡献。单一LID设施方案中,绿色屋顶对径流量和峰值流量的削减率最大,下凹式绿地对污染物总负荷的削减效果最佳;LID设施组合方案是减少径流和面源污染最有效的方案,然而下凹式绿地是最具成本效益的LID设施选择。In order to study the effect of low impact development(LID) on urban stormwater runoff, four LID schemes were proposed based on the current development of a certain area in Qingdao. HYSWMM was used to simulate and analyze the control effect of each scheme on the runoff and non-point source pollution under five rainfall return periods, and a cost-effectiveness analysis was conducted by calculating the life-cycle costs. The results showed that the LID practices contributed significantly to the surface runoff and non-point source pollution mitigation in the study area. In the single LID scheme, green roof had the greatest reduction rate on the runoff and peak flow, and sunken green space had the greatest reduction rate on the total pollution load. The combined scheme was the most effective scheme to reduce runoff and non-point pollution, whereas the sunken green space was the most cost-effective LID option.
