摘要：

Zooplankton ecolgy,including species composition,population dynamics and biomass,was studied in the Xixi river,Hangzhou During one year study,137 species (42 Protozoa,63 Rotifera,22 Cladocera and 10 Copepoda)were found. Annual average density of zooplankton were 809 ind·L -1,with biomass 1.425 mg·L -1,diversity index 2.87.Cladocera biomass had a positive linear relationship with water depth, chlorophyll a and NO 3-N content.Water pollution was amplified gradually down stream in the Xixi river
