| 摘 要： | 2014年1-10月调查太平湖4季的浮游生物状况,共鉴定浮游植物7门56属89种,其中绿藻门种类最多(总种数的39.33%),其次为硅藻门(22.47%)、蓝藻门(16.85%);浮游植物各季节生物量为0.69~4.26 mg·L~(-1)、平均生物量1.86 mg·L~(-1);浮游植物各季节Shannon-Wiener多样性指数为1.07~1.66,Pielou均匀度指数0.53~0.71。共采集到浮游动物20科40属52种,其中原生动物7种、轮虫27种、枝角类12种、桡足类6种。浮游动物各季节生物量范围为0.67~1.68 mg·L~(-1)、平均生物量1.17 mg·L~(-1);浮游动物各季节Shannon-Wiener多样性指数为0.89~2.15,Pielou均匀度指数为0.41~0.73。综合判断太平湖水体为中营养化状态。根据太平湖浮游生物调查结果估算其鲢、鳙鱼产力分别为1 348 t和1 922 t。

| Abstract: | From January to October,2014,a seasonal investigation on plankton species composition was carfied out in Taiping Lake that is located in the north of Huangshan city,Anhui Province and connected to the Yangtze River via Qingyi River.The result showed that there were 89 phytoplankton species belonging to 7 phylums 56 genera in the lake.The range of phytoplankton was 0.69-4.26 mg·L-1 and its average biomass was 1.86 mg·L-1.Chlorophyta was the main species (39.33％ of the sum),followed by Bacillariophyta (22.47％ of the sum) and Cyanophyta (16.85％).The Shannon-Wiener diversity index and Pielou evenness index of phytoplankton ranged from 1.07 to 1.66,0.53 to 0.71,respectively.Fifty-two species belonging to 20 families 40 genera of zooplankton from four categories were identified.The biomass of zooplankton ranged from 0.67 tol.68 mg·L-1 with an average biomass of 1.17 mg·L1.The amount of the Protozoa,Rotifer,Cladocera and Copepoda of the zooplankton were 7,27,12 and 6 species,respectively.The Shannon-Wiener diversity index and Pielou evenness index of zooplankton ranged from 0.89 to 2.15 and from 0.41 to 0.73,respectively.In conclusion,the water in Taiping Lake was mesotrophication according to the comprehensive evaluation of our investigation results.The productions of silver carp and bighead carp were estimated about 1 348 t and 1 922 t based on the productivity of plankton in the lake. |
