%X The plankton community composition were investigated in Jing River of Ningxia section from July to August in 2010.The results showed that: 81 species (genera), 6 phylum of phytoplankton were observed in the whole paragraph. The density of phytoplankton was 1.1 × 104 ~ 11.6 × 104 cells L-1; the average density was 4.37 × 104 cells L-1; the range of biomass was 0.024 ~ 0.21 mg L-1, the average biomass was 0.057 mg L-1. At the same time, 54 species(genera),4 phylum of zooplankton were observed, the density was 60 ~ -185 ind L-1;the average density was 107.73 ind L-1; the range of Biomass was 0.02~ 0.662 mg L-1, an average was 0.24 mg L-1; the comprehensive index of plankton in Jing River showed that: In Jing River , the water quality was good; the composition and structure of community was instability, so, the plankton community composition was interferences by external environment susceptibility.
