摘要
Abstract
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.关键词
