摘要
采用优势指数、多样性指数等方法,分析了2007年东平湖浮游植物的组成与变动。分析得出:2007年东平湖浮游植物共有8门83种,其中蓝藻门为主,绿藻门和硅藻门的含量次之,优势种以蓝藻门中的色球藻和席藻为主;根据香农多样性指数等综合分析,2007年东平湖水质以中度污染为主,重污染和轻污染水域面积较少,且有一定的季节性,3月份的水质略好。
By using index of advantage, index of diversity and correlative methods, this paper evaluated the composition and alteration of phytoplankton in Dongping Lake in 2007. The analysis result indicated： phytoplankton in Dongping Lake had eight phylum including eighty -three species, cyanophyta was in the majority, chlorophyta and bacillariophyta took the second place, the dominance species were chroococcaceae and phormidium which were belonged to phytoplankton; According to Shannon - Wiever multiple indices analysis, the Dongping Lake water quality was primarily moderate polluted, the heavy pollution and the light pollution water area were few, and had certain seasonal characteristic, water quality was comparatively better in March.
