摘　　要：为满足低影响开发(low impact development, LID)组合在城市雨洪管理过程中良好的应用效果和经济效益,应用暴雨洪水管理模型(stormwater management model, SWMM)结果指标和项目全生命周期成本理论,构建不同LID组合方案下的环境-成本效益综合评价系统,并通过数值模拟和数理分析相结合的方法评估各备选方案的综合效益。为验证理论模型的可行性,将9种不同布设比例的LID组合分别嵌入实际项目中进行模拟和评估。结果表明,综合效益最高的LID组合为“45%的绿色屋顶+15%的植草沟+30%的雨水花园+70%的透水铺装”,其径流总量削减率为52.83%、4类污染负荷削减率均为80%以上且每年消耗的总成本费用为22 416 350元。该评价体系为优化城市可持续雨洪管理提供新思路,同时为建设开发海绵城市提供方案指导。In order to meet the good application effect and economic benefits of low impact development(LID)combinations in the urban stormwater management process.By applying the stormwater management model(SWMM)results indicators and the whole life cycle cost theory of the project,a comprehensive evaluation system of the environmental-cost effectiveness of different LID combinations is constructed,and the comprehensive benefits of each alternative are assessed by the combination of numerical simulation and mathematical analysis.To verify the feasibility of the theoretical model,nine LID combinations with different deployment ratios were embedded in actual projects for simulation and evaluation respectively.The results show that the LID combination with the highest overall benefits is"45%green roof+15%grass swales+30%rain gardens+70%permeable paving",with total runoff reduction rate of 52.83%,reduction rate of over 80%for all four types of pollution loads and total annual cost of 22416350 Yuan.This evaluation system provides new ideas for optimising sustainable urban rainwater management and provides guidance for the construction and development of sponge cities.
