| 摘要: |
| 研究了太平湖水库底栖动物群落组成(1992-1993年),定量样品中共出现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年的资料比较,种类数减少,现存量显著增加,生物量由0.562g/m2增加到3.90g/m2。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物量与水深负相关显著。对底栖动物资源的渔业合理利用进行探讨。 |

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