Abstract: An investigation on the phytoplankton was conducted in Xiaoheli River Resesvor and its upstream rivers from 12 sample stations with 60 species belonging to 6 divisions in spring,2012. Bacillariophyta accounted for most with the ratio of59. 09% in the reservoir,while Chlorophyta accounted for the most with the ratio of 44. 74% in the river. Average abundance of different sampling sites in reservoir（4 878. 5 ×104ind / L） is higher than that in the river（319. 4 ×104ind / L）.Meanwhile,average biomass of different sampling sites in reservoir（2. 67 mg / L） is smaller than that in the river（2. 86mg / L）. Dominant specie is Aphanocaspsa elachista existing only in the reservoir. By TLI,all sampling stations are Oligotropher-Mesotropher. By many-dimensions（MDS） analysis,there are many differences in community structure of phytoplankton between Xiaoheli river reservoir and its upstream rivers.
