摘　　要：以我国海绵工程实施较早、规模较大的池州市的典型海绵工程单项措施(雨水花园、植草沟)为研究对象,通过跟踪监测已实施海绵工程改造和未实施改造的两个居民区内径流雨水水质,探究海绵工程改造对居民区径流污染的减排效应.结果表明:改造后小区出水污染物浓度显著低于未改造小区;雨水花园较植草沟出水污染物浓度更低,水质更稳定.最后对雨水花园和植草沟的技术经济指标进行了分析.Using a typical sponge city initiative(rain garden and grassed swale)in Chizhou,one of the earliest and largest sponge projects in China,as the research object,we tracked and monitored manholes in two residential areas one where the sponge project was implemented and one without transformation.Effluent quality of runoff rainwater was monitored to investigate the emission reduction effect of pollutants from the sponge project on runoff in residential areas.The results showed that the concentration of effluent pollutants in residential areas after renovation was significantly lower than that in unmodified rural areas.Rain gardens had lower concentrations of effluent than those in grassed swale,and the water quality of rainwater gardens was more stable.Finally,the economic and technical indicators of rain garden and grassed swale were analyzed.
