Analysis on Community Structure and Biodiversity of Fish in Dongting Lake
摘要
Abstract
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.关键词
