| 摘 要： | 为了解红枫湖水体状况及其浮游植物的多样性和群落结构,在红枫湖选择18个典型的采样点,于2010年10月和12月两次采样,对所采集植物进行定性、定量分析。结果表明,目前红枫湖有浮游植物8门13目1亚目23科37属55种,其中,绿藻门种类最多,共21种,占总数的38.2%;蓝藻门次之,共15种,占总数的27.3%;硅藻9种,占16.3%;甲藻和黄藻各3种,分别占5.5%;金藻门2种,占3.6%;裸藻和隐藻各1种,各占1.8%。红枫湖浮游植物平均数量和平均生物量分别为7.5×105个/L和1.79mg/L。优势种为小环藻、色球藻和小球藻,优势度分别为0.407、0.048和0.077。与1996年相比,主要优势种发生了变化,但浮游植物群落结构仍以绿藻为主,蓝藻次之。红枫湖浮游植物多样性和均匀度分别在2.01～2.68和0.35～0.50,表明,红枫湖水体状况优于1996年。
