The present paper deals with the community of zoobenthos in the Taipinghu reservoir, Anhui Province. In quantitative samples, 26 species or genera of zoobenthos were observed during 1992-1993. Most of them are Oligochaeta and Chironomidae larvae, only one species of Mollusca was present. The standing crop exhibits a seasonal variation. The species number has decreased, but the standing crop increaseed from 0.56g/m² wet weight to 3.90g/m² as compared with the data obtained in 1985-1986, however, the index of biological diversity is relatively lower. The analyses of correlation between the parameters of zoobenthos and the environmental factors demonstrate that there is a significant positive correlation between the biomass of Oligochaeta and the total nitrogen and total phosphorus of the sediment, and a significant negative correlation between those of aquatic insects and water depth (P<0.05). Finally, the vstrategies of the raional, high-efficiency exploition of zoobenthos are also discussed for the development of fishery in the reservoir.
