摘　　要：2008—2009年通过对红枫湖水库浮游植物及环境因子进行采样调查,并运用综合营养状态指数对红枫湖水库营养状态进行评价。研究结果显示,红枫湖水库浮游植物全年以蓝藻、绿藻为主的优势种群落,且在2008—2009年经常性局部发生蓝藻水华:冬、春季节主要是水华束丝藻(Aphanizomenon flos-aquae)的蓝藻水华;夏季主要是微囊藻属(Microcystis)蓝藻水华;秋季浮游植物主要是颗粒直链藻(Melosira)和小环藻属(Cyclotella)为主的硅藻类群,未出现水华现象。通过综合营养状态指数计算得红枫湖水库水体水质处于富营养化状态。By the investigated of phytoplankton and nutrients in Hongfeng Lake Reservoir＇s in 2008--2009. The Hongfeng Lake Reservoir phytoplankton＇s dominant species communities is cyanobacteria, chlorophyta all year. There is regular partical eyanobacterial blooms occurred in the Hongfeng Lake Reservoir between 2008 and 2009. Its discipline is that Aphanizomenon flosaquae is blomms in winter and spring, Microcystis is blomms in summer. It didn＇t have alga blooms occurred and its dominant species is Melosira and CycloteUa in autumn. The Hongfeng Lake Reservoir＇s reaches eutrophication level to eutrophication level by trophic state index.
