摘    要:调查了武汉南湖浮游植物的群落结构,在5个采样站鉴定出浮游植物67种,隶属于7门24科43属,其中绿藻门种类最多(28种),金藻门最少(1种)。浮游植物平均密度为2.489×106ind./L,秋季最高为2.979×106ind./L,夏季最低为1.949×106ind./L;平均生物量为7.94 mg/L,其中隐藻生物量最高,为2.33 mg/L,甲藻和金藻最低,分别为0.06 mg/L和0.01 mg/L;浮游植物的密度和生物量在5个采样站之间无显著性差异,其M argalef多样性指数较低,在1~2之间。

关 键 词:浮游植物  密度  生物量  Margalef多样性指数  武汉南湖

Abstract:Phytoplankton community structure of Lake Nanhu was investigated.Totally 67 species belonging to 43 genera,24 families,7 phyla were identified at five sampling stations.The chlorophyta had the most species and the chrysophyta had the least.The average density of phytoplankton was 2.4×106 ind./L,with a maximum of 2.979×106 ind./L in autumn and a minimum of 1.949×106 ind./L in summer.The average biomass of phytoplankton was 7.94 mg/L,with a maximum of 2.33 mg/L for cryptophyta and a minimum of 0.06 mg/L for pyrrophyta and 0.01 mg/L for chrysophyta.There were no significant differences of phytoplankton density and biomass among the five stations and the Margalef diversity index of phytoplankton was low,between 1 and 2.
Keywords:phytoplankton  density  biomass  lake Nanhu of Wuhan  Margalef diversity index
