摘要
以重庆市渝北区悦来生态城为研究区域,选取并采集已有的典型海绵设施土壤样本,采用密度分离方法提取出TWP,对不同类型海绵设施中的TWP进行提取后定性定量分析,并对此次实验数据进行TWP在海绵设施中的"汇""源"分析,评估了TWP在不同海绵设施中的生态释放风险.结果表明,各海绵设施采样点均处于低风险级别.生态风险指数从高到低依次为停车场＞雨水集点＞下水道口＞生物滞留带＞雨水花园.其中停车场生态风险指数为31,下水道口、生物滞留带及雨水花园生态风险指数均小于10.
Abstract
The paper took the Yuelai eco-city in Yubei district of Chongqing as the study area,selected and collected soil samples from existing typical sponge facilities,extracted TWP by density separation method,analyzed TWP in different types of sponge facilities qualitatively and quantitatively after extrac-tion,and analyzed the"sink"and"source"of TWP in sponge facilities for this experiment.The"sink"and"source"analysis of TWP in sponge facilities was conducted to assess the ecological release risk of TWP in different sponge facilities.The result showed that the sampling points of each sponge facility were currently at low risk level.The ecological risk indexed from high to low is parking lot＞rainwater catch-ment point＞sewer inlet＞bioretention zone＞rain garden.The ecological risk index of the parking lot was 31,and the ecological risk index of the sewer inlet,bioretention zone and rain garden were all less than 10.
