摘　　要：为探究低影响开发(LID)对平原河网地区的城市径流和水质控制效果,以张家港中心城区的东北分区为例,提出针对LID设施组合方案雨洪控制效果的多控制目标综合评价体系。通过构建SWMM模型,模拟在1 a一遇、2 a一遇、5 a一遇、10 a一遇、20 a一遇降雨情形下,不同LID设施组合方案的径流控制效果和污染物削减能力;并构建水文、水力、水质效应、成本投入4方面评价指标体系,采用灰色关联分析法对4种组合方案进行比选。结果表明,各项方案在低重现期降雨条件下均能发挥一定控制作用,但遭遇高重现期降雨时,控制作用受到限制。在4种组合方案中,包含透水铺装、绿色屋顶和雨水花园组合方案总体效益最佳,研究结果可为建设海绵城市提供一定理论依据。In order to explore the effectiveness of low impact development(LID)measures on urban runoff and water quality control in plain river network areas,the northeast district of the central urban area of Zhangjiagang City is selected as a case study.A comprehensive evaluation system for LID facility combination schemes is proposed,focusing on multi-objective control of storm water.By constructing a SWMM model,the runoff control effects and pollutant reduction capabilities of different LID facility combinations are simulated under 1 a,2 a,5 a,10 a and 20 a rainfall events.An evaluation index system covering hydrological,hydraulic,water quality effects and cost investment aspects is established,and the grey relational analysis method is used to compare and select among the four combination schemes.The results indicate that all schemes can play a certain control role under low recurrence period rainfall conditions,however,their effectiveness is limited when encountering high recurrence period rainfall.Among the four combination schemes,the one that includes permeable pavements,green roofs and rain gardens demonstrates the best overall benefits.The findings of this study can provide a theoretical basis for the construction of sponge city projects.
