| 摘 要： | 采用生物多样性指数方法,对2013年阳宗海湖泊的浮游生物群落结构进行研究。结果表明,阳宗海湖泊共检出浮游植物7门39属,蓝藻门的拟鱼腥藻和泽丝藻为优势种群;浮游动物鉴定出33种,轮虫为优势种;浮游植物和浮游动物的香浓多样性指数在1.10~2.83之间,均匀度指数在0.37~0.88之间,属于中度污染,阳宗海湖泊已处于中营养状态,并有向富营养化过渡的趋势。

| Abstract: | A research on phytoplankton community structure of Yangzonghai Lake in 2013 was carried out with the method of biodiversity index. The results show that there are 7 phyla 39 genera of phytoplankton in Yangzonghai Lake, Anabaenopsis sp. and Limnothrix sp. being the dominant species of cyanophyta; and there are 33 species of zooplankton, Rotifera being its dominant species; the Shannon-Weaner index and the evenness index of phytoplankton and zooplankton are 1. 10 ~2. 83 and 0. 37~ 0. 88, respectively, belonging to the state of moderate pollution. The Yangzonghai Lake has been in the nutritional status with the trends of transition to eutrophication. |
