摘　　要：为了探究新恢复湿地对近岸水体的深度净化与水生态功能提升效果,于2017年8月—2019年4月对鹦鹉洲生态湿地各生态单元进出水水质进行监测,并分析了湿地内各个组块对污染物去除的贡献。结果显示,鹦鹉洲生态湿地对来水中NH4^(+)-N、NO2^(-)-N和NO3^(-)-N的平均去除率分别为49.2%、46.3%和52.9%,对溶解性无机磷(DIP)和TP的平均去除率分别为53%和55%,对SS的平均去除率为59.6%;湿地不同区块的协同作用可以实现对多种污染物的有效去除,有效提升了水体透明度,深度净化了水质。In order to explore the effect of newly restored wetland on advanced purification of coastal water and improvement of water ecological function,the influent and effluent quality of each ecological unit of Yingwuzhou wetland in Shanghai was monitored from August 2017 to April 2019,and the contribution of each block in the wetland to pollutants removal was analyzed.After treated by the Yingwuzhou wetland,the average removal rates of ammonia nitrogen(NH4^(+)-N),nitrite nitrogen(NO2^(-)-N)and nitrate nitrogen(NO3^(-)-N)were 49.2%,46.3%and 52.9%,respectively,the average removal rates of dissolved inorganic phosphorus(DIP)and total phosphorus(TP)were 53%and55%,respectively,and the average removal rate of suspended solids(SS)was 59.6%.Synergistic effect of different wetland areas could effectively remove different pollutants and improved the water transparency,which deeply purified the water quality.
