摘　　要：海绵城市建设是通过构建生态基础设施,增强城市雨水径流吸收、储存、下渗、净化和排放的能力,用以应对城市水资源短缺和洪涝灾害,并改善水环境,提升城市生态环境质量。以嘉兴市为例,选取了海绵化改造区域和未改造区域的20个目标样本,对其雨水径流水质进行研究分析,探索了不同用地性质下径流水质的变化情况,并提出了建设用地海绵化改造的具体措施和实施方案,为后续海绵城市建设提供了新思路。Sponge city construction is to enhance the capacity of the absorption,storage,infiltration,purification and discharge of urban rainwater runoff by constructing ecological infrastructure,in order to cope with urban water resource shortage and flood disasters,improve the water environment and enhance the quality of the urban ecological environment.This article takes Jiaxing City as an example,selects 20 target samples from both sponge transformation areas and unmodified areas to study and analyze their water quality of rainwater runoff,explores the changes of runoff water quality under different land use properties,and proposes specific measures and implementation plans for the sponge transformation of construction land,which provides new ideas for subsequent sponge city construction.
