对2005—2007年阳宗海浮游植物生物量数据进行了监测分析。结果显示：浮游植物生物量总体呈下降趋势；浮游植物平均生物量在水体中空间分布呈现差异性分布，中部＞北部＞南部；中部和北部浮游植物生物量变化较大，南部变化较小；湖泊水体目前处于中营养状态。

The phytoplankton biomass in Yangzonghai Lake from the year of 2005 to 2007 was monitored and ana-lyzed.The results showed that the phytoplankton biomass was decreasing in general.The spatial distribution of the average phytoplankton biomass in the water was difference.The biomass in the middle part of the lake was more than that of the north and much more than the south.The biomass in the middle and north part of the lake have changed dramatically.However,the change in the south was small.Yangzonghai Lake was mesotrophic currently.
