An artificial floating-island ecosystem including plants,fishes and shellfishes was used for water quality management and ecological restoration in Bailianjing River,Shanghai.Results showed that removal rate of TN,TP and CODMn was 60.7%.43.7% and 35.0% and chlorophyll-a decreased by 38.2% by Acorus gramineus Var.pusillus+filter-feeding fishes+Hyriopsis cumingii(Lea)system.Removal rate of TN,TP and CODMn was 55.2%,37.2% and 42.5%,and chlorophyll-a decreased by 44.3% by lmperata cylindrical Red Baron+ filter-feeding fishes+Byriopsis cumingii(Lea) system.Removal rate of TN,TP and CODMn was 55.1%,29.7% and 28.3% and chiorophyll-a decreased by 26.0% by Acorus calamus Linn+filter-feeding fishes+Hyriopsis cumingii(Lea)system.On the whole,the artificial floating-island ecosystem can enhance standard of TP from Grade Ⅲ to Ⅱ,TN from inferior Grade Ⅴto Ⅳ and CODMn from Grade Ⅳ to Ⅲ.Results of water treated by combined artificial floating-island ecosystem are more efficient than single species of ecological system.Number of the organism is on the rise and improving the landscape of the water.
