摘　　要：于2005年6月至2006年6月对巢湖东湖区的浮游动物进行了采样调查,初步研究了巢湖东湖区的浮游动物的种类组成、群落结构特征以及浮游动物物种的多样性,并对巢湖东湖区的水质状况和营养类型作出了评价。研究结果显示浮游动物153种,其中原生动物43属59种,占总种数的38.56%;轮虫类20属48种,占总种数的31.37%;枝角类14属26种,占总种数的16.99%;桡足类20种,占总种数的13.07%。浮游动物的物种多样性随着季节的变化而变化;污生指数法评价结果表明巢湖东湖区的水质状况从2005年6月至2006年6月均处于β-中污带级;用浮游动物数量(ind·L-1)作为湖泊水体营养程度的生物量指标,其结果显示巢湖东湖区水体从2005年6-9月和2006年3-6月巢湖东湖区水体的营养状况处于富营养状态。The study investigated the species composition, community structure and species diversity of zooplankton in the eastern zone of Lake Chaohu and analyzed the water quality and the type of nourishment from June 2005 to June 2006. And one hundred and fifty-three species of zooplankton were found, of which fifty-nine species were Protozoa(38.56%), forty-eight species were Rotifera(31.37%), twenty-six species were Cladocera(16.99%), twenty species were Copepoda(13.07%). The Margralaf Index showed that the species diversity was very low during the study period and the species diversity was varied with the season. The results from the analysis of saprobic system showed that from June in 2005 to June in 2006 the eastern zone of Lake Chaohu was in the state of β-mesosaprobic zone. By using the quantity of zooplankton as the biology quantity index of nourishing degree in lakes, the eastern zone of Lake Chaohu was in the state of eutrophication from June to September in 2005 and from March to June in 2006.
