摘　　要：低影响开发(LID)是海绵城市建设的重要工程措施,分析LID各结构层对径流的蓄滞作用,模拟其对径流的削减和延滞效果,对LID设计方案的可行性评估至关重要。以南方某小区为研究对象,基于城市水系统控制仿真模型软件Simuwater构建区域产汇流计算和LID效果评估模型,探讨Simuwater在LID效果评估的适用性。结果表明,Simuwater连续性误差满足精度要求,而且Simuwater能够较为精细地模拟各结构层的蓄滞作用,比较准确地计算LID方案径流总量控制率和污染物削减率。Low impact development(LID)is an important engineering measure for sponge city construction,It is very important for the feasibility evaluation of LID design scheme to analyze the storage effect of each structural layer of LID on runoff and simulate its reduction and delay effect on runoff.Taking a community in southern city as the research example,and based on the urban water system control simulation model Simuwater,the runoff calculation and LID facility effect evaluation model is built to explore the applicability of Simuwater in LID effect evaluation.The results show that the continuity error of Simuwater model meets the accuracy requirements,and Simuwater can more finely simulate the detention effect of each structural layer,and accurately calculate the total runoff control rate and pollutant reduction rate of LID scheme.
