摘　　要：本文以宿鸭湖水库浮游生物为研究对象,对夏季宿鸭湖水库浮游生物的多样性进行评估,为宿鸭湖水库的生态保护提供理论基础。调查结果为:宿鸭湖水库共检测出85种(属)浮游植物,平均密度是4.54×10~6cells/L,包括6个门,其中绿藻门45种(属),硅藻门21种(属),蓝藻门9种(属),裸藻门5种(属),黄藻门3种(属),隐藻门2种(属);浮游动物22种(属),平均密度是3.92×104 ind/L,包括4类,其中原生动物11种(属),轮虫类6种(属),枝角类3种(属),桡足类2种(属)。浮游植物的Shannon-Wiener多样性指数、Margalef丰富度指数和Pielou′s均匀度指数的平均值分别是1.700、2.076和0.478;浮游动物的Shannon-Wiener多样性指数、Margalef丰富度指数和Pielou′s均匀度指数的平均值分别是1.594、0.824和0.707。参照生物多样性阈值的分级评价标准,宿鸭湖水库的浮游生物多样性较好。Taking the plankton of Suya Lake reservoir as the research object,this paper evaluates the plank-ton diversity of Suya Lake reservoir in summer,and provides a theoretical basis for the ecological protection of Suya Lake reservoir.The results were as follows:A total of 85 species of phytoplankton were detected in Suya Lake reservoir,with an average density of 4.54×106 cells/L,including 6 phyla,including 45 chlorophyta(genera),21 diatoma(genera),9 cyanophyta(genera),5 gymnophyta(genera),3 xanthophyta(genera)and 2 Cryptophyta(gener-a).There were 22 species of zooplankton with an average density of 3.92×104 ind/L,including 4 species,including 11 protozoa(genera),6 rotifers(genera),3 cladoceras(genera)and 2 copepods(genera).The mean values of Shannon-Wiener diversity index,Margalef richness index and Pielou's evenness index were 1.700,2.076 and 0.478,respec-tively.The mean values of Shannon-Wiener diversity index,Margalef richness index and Pielou's evenness index were 1.594,0.824 and 0.707,respectively.According to the classification and evaluation criteria of biodiversity threshold,the plankton diversity of Suya Lake reservoir is better.
