Abstract: The community structure and spatio-temporal pattern of zoobenthos in Guanting Reservoir were studied from March,2007 to December,2007.The results showed that a total of 43 species were identified,belonging to 4 phyla,24 families and 42 gena;The dominant species were Limnodrilus hofmeisteri,Tanypus punctipennis and Tokunagayusurika akamusi,with annual average density of 5 037 ind./m2and biomass of 39.80 g/m2.The maximal and minimal densities and biomasses of the zoobenthos were observed in winter and summer.The density and biomass of chironomidae were found high below ice,Tokunagayusurika akamusi being 9 136 ind./m2and biomass of 64.39 g/m2in Wukeshu sampling station in December.The maximal annual average density and biomass of zoobenthos were found in Xiaying sampling station.The annual average value of Shannon-Wiener diversity index was 2.03 and that of Pielou index 0.56.The polluted-tolerance species L.hofmeisteri,T.punctipennis and T.akamusi overwhelmed the community,indicating that the reservoir was seriously in eutrophication.The density of zoobenthos with total phosphorous level(TP)and temperature were to be significant negatively correlated(P＜0.01),with chlorophyll-a significant negatively correlated(P＜0.05),with NO-N and pH significant positively correlated(P＜0.01),with PO-P,NO-N,SD,and water depth significant positively correlated(P＜0.05),with TN not significant correlated(P＞0.05).Correlation between biomass of zoobenthos and environment factors was not significant(P＞0.5).
