对滇池浮游藻类群落组成和空间分布开展了2次调查，鉴定出藻类8门66属159种及变种，绿藻种类最多，蓝藻次之。5、12月滇池全湖平均藻类密度分别为1?398×108、2?180×108个/升，蓝藻门微囊藻属为优势藻类。5月的调查中滇池外海藻类生物量呈北高南低的格局，而12月则呈现南部和中部高，北部低。外海的藻类生物量明显高于草海，草海藻类群落构成与外海明显不同，主要表现为绿藻门藻类所占比例较高。12月滇池外海及全湖藻类生物量都显著高于5月。与上一次（2006-2007年）滇池浮游藻类的系统调查相比，滇池（主要是外海）浮游藻类在物种数量、常见藻类、优势藻类及生物量水平方面与之接近。

The species composition and temporal distribution of Dianchi phytoplankton was studied in May 2012 and December. A total of 159 algae species belonging to 66 genera, 8 phyla were identified. The dominant taxa were Chlorophyta and Cyanophyta, with the species number in the order of Chlorophyta > Cyanophyta. The average density of phytoplankton community reached 1?398 × 108 cell/L and 2?180 × 108 cell /L in May and December separately. Microcystis Kutz, Cyanophyta, was the highest cell proportion. The average density of phytoplankton community was higher in northern lake than that in southern lake in May, but this density was lower in northern lake than that in southern and middle lake in December. Algal biomass was significantly higher in outer lake than inner lake, but there was higher cell proportion of Chlorophyta in inner lake than outer lake. Algal biomass was significantly higher in December than in May. Compared with the phytoplankton investigation in Dianchi Lake from April 2006 to May 2007, few difference was found about the number of algae species, common species, dominant species and biomass levels in Dianchi Lake ( mostly outer lake of Dianchi) .
