| 摘 要： | 研究了太平湖水库底栖动物群落组成（１９９２－１９９３年）定量样品出现２６种（属），主要是寡毛类和摇蚊科幼虫，软体动物只有１种，现存量有明显的季节差异，本次调查结果与１９８５－１９８６年资料比较，种类数减少，现存量显著增加，生物量由０．５６２ｇ／ｍ＾２增加到３．９０ｇ／ｍ＾３生物多样性指数偏低，底栖动物的参数与环境因素进行了相关分析，寡毛类的密度和生物量与总氮，总磷正相关，水生昆虫的密度和生理量与水

| Abstract: | 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 strategies of the raional, high-efficiency exploition of zoobenthos are also discussed for the development of fishery in the reservoir. |
