To evaluate the restoration from the contaminative water condition of five rivers,which are Wuchaogang River,Zhoujiabang River,Shuichengluzhoujiabang River,Caoyanghuanbang River and Liwa River in the outskirts unit of southwest Shanghai,the investigations of the spatial variations of zooplankton community structure,biomass and eleven chemical and physical parameters were undertaken from February to April,2007.The water quality of these rivers were assessed by both biological methods(qualitative and quantitative analyses of zooplankton community and bio-diversity indexes) and chemical methods(Integrated pollution index and Chemical evaluation index),respectively.The result showed that 16 species of zooplankton were sampled,consists of 11 Rotifcra,4 Cladocera and 1 Copepoda.Dominant species were Rotaria neptunia,Brachionus calyciflorus,Filinia minuta and Daphnia cucullata respectively.Based on the integrative evaluation of the biological and the chemical methods,it was suggested that the water quality of the five rivers can be sorted from α type of medium pollution to multi-polluted type.Meanwhile,our study indicates that the five rivers which used to be were malodorous and black rivers before artificially integrative treatment had recovered gradually,however,its aquatic ecosystems still has remained unstable,which the zooplankton communities were strongly affected by contaminative water and the species and components were shown as relatively simple.It was suggested that management has to put more efforts for the river restoration in order to establish the aquatic biodiversity and the healthy and self-management system.
