| 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。

| Abstract: | 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. |
