太湖浮游动物群落结构调查

Investigation on Community Structure of Zooplankton in Taihu

2013年5月和9月对江苏省太湖13个点位进行浮游动物群落结构调查。结果表明,太湖13个点位共获得63种浮游动物,其中轮虫类24种、枝角类12种、桡足类12种、原生动物15种;浮游动物密度为408头/L,原生动物的砂壳虫(Difflugia sp.)为优势种,占38.7%。太湖浮游动物密度与多样性秋季均优于春季。

Zooplankton communities at 13 sites in Taihu Lake,Jiangsu Province,China were investigated and analyzed in May and September of 2013. There were 63 zooplankton species in Taihu Lake,including 24 trochelminthes,12 cladocera,12 copepoda,and 15 protozoan. Meanwhile,the density of zooplankton community was 408 individual per litre in Taihu Lake,and the dominant taxa was Difflugia sp.,accounting for38. 7%. The density and diversity of zooplankton communities in autumn were higher than in spring in Talihu Lake.
