摘　　要：2012年4～5月对丹江陕西段浮游植物群落组成进行了调查。结果表明,该河段浮游植物种类为5门、36种(属),密度为0.05×104～39.2×104个/L,平均密度为17.65×104个/L,生物量为0.55～0.000 015 mg/L,平均生物量为0.21 mg/L。浮游植物多样性指数分析表明,该河段水质良好,但浮游植物群落结构不稳定,易受外界的干扰。The phytoplankton community composition was investigated in Danjiang River of Shanxi section from April to June in 2012.The results showed that： 36 species（genera）,5 phylum of phytoplankton were observed in the whole paragraph.The density of phytoplankton was 0.05×104-39.2×104 ind/L;the average density was 17.65×104 ind/L;the range of biomass was 0.55-0.000 015 mg/L,the average biomass was 0.21 mg/L.The comprehensive index of phytoplankton in Danjiang River showed that： in Danjiang Rive,the water quality was good;the composition and structure of community was instability,so,the phytoplankton community composition was interfered by external environment susceptibility.
