摘  要：
[目的]对洞庭湖鱼类群落结构及生物多样性进行分析。[方法]通过对洞庭湖鱼类资源进行初步调查,并对洞庭湖鱼种类情况、鱼类生物量情况、优势鱼类情况以及鱼类多样性情况进行了分析。[结果]洞庭湖各区域鱼类物种数量均相差不大,其生物量最多的是鲤鱼。洞庭湖优势种鱼类比例依次为鲤科、鮠科、鮨科、鳅科。洞庭湖鱼类Shannon-Wiener(H1)指数的变化范围为1.681~2.511,丰富度(R)指数的变化范围为1.851~2.584,Pielou(J')指数的变化范围为0.581~0.879。相关性分析表明,洞庭湖鱼类Shannon-Wiener(H1)指数与丰富度(R)指数、Shannon-Wiener(H1)指数与Pielou(J')指数均呈高度相关性。[结论]该研究结果可为洞庭湖的生态修复提供理论基础。

摘  要：
[Objective] The aim was to analyze community structure and biodiversity of fish in Dongting Lake. [Method] Fish resources in Dongting Lake was investigated,fish species,fish biomass,dominant species and diversity were analyzed. [Result]The results showed that the number of fish species in all areas of Dongting Lake were not quite different,and the largest biomass was carp. The dominant fish species in Dongting Lake were Cyprinidae,Bagridae,Serranidae,Cobitidae. The variation range of the Shannon-Wiener( H1) index of the Dongting Lake fish was between 1. 681- 2. 511,the range of richness( R) index was between 1. 851- 2. 584,and the variation range of Pielou( J') index was between 0. 581- 0. 879. The correlation analysis showed that the Shannon-Wiener( H1) index and richness( R) index,Shannon-Wiener( H1)index and Pielou( J') index were all highly correlated.[Conclusion]The study can provide theoretical basis for ecological restoration of Dongting Lake.
