Abstract: 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稬-1,with biomass 1.425 mg稬-1,diversity index 2.87.Cladocera biomass had a positive linear relationship with water depth, chlorophyll a and NO3-N content.Water pollution was amplified gradually down stream in the Xixi river.

Key words: Quercus aliena var. acuteserrata, clear-cutting site, soil respiration rate, soil temperature, soil moisture.
