%X In June-July 2006, investigations were made on the zooplankton in the mainstream of Yili River and its three main tributaries (Tekes River, Künes River and Kax River), two reservoirs (Qiapuqihai Reservoir and Jilintai Reservoir), intermittent waters, and ponds in Yili region of Xin-jiang. A total of 217 species belonging to 134 genera were identified, among which, Protozoa and Rotifer were the main groups, which contained 153 species (71% of the total species number) of 95 genera and 51 species (23% of the total) of 27 genera, respectively. Only 8 species of Cladocera and 5 species of Copepoda were observed. The zooplankton richness ranged from 7 to 132, with the lowest (7) in Jilintai Reservoir, and the highest (132) in Yili River. Qiapuqihai Reservoir had the highest density and biomass of zooplankton (11391 ind x L(-1) and 2.79 mg x L(-1), respectively), but Tekes River had the lowest density (578 ind x L(-1)) and Kax River had the lowest biomass of zooplankton (0.03 mg x L(-1)). Pearson correlation analysis and linear regressions showed a significantly negative relationship between zooplankton species number and water flow velocity. Based on the species number, density, and biomass of zooplankton, it was found that Yili River and its three main tributaries were in oligotrophic status, while Qiapuqihai Reservoir and Jilintai Reservoir were in mesotrophic status.
