摘　　要：2012年4～5月对丹江陕西段浮游动物群落组成进行了调查。结果表明,该河段浮游动物种类为3门17种(属),密度为10～160ind/L,平均密度为100 ind/L。浮游动物的生物量为0.001 6～17.5 mg/L,平均生物量为9.023 mg/L。浮游动物多样性指数分析表明该河段浮游动物群落结构不稳定,易受外界的干扰。The zooplankton community composition was investigated in Danjiang River of Shanxi section from April to May in 2012. The re- sults showed that there are 3 phylum 17 species （genera） , the density was 10 - 160 ind/L, the average density was 100 ind/L. The range of biomass was 0. 001 6 - 17.5 mg/L, the average biomass was 9. 023 mg/L. The comprehensive index of plankton in Danjiang River showed that ： the composition and structure of community was instability, the zooplankton community composition was interfered by external environ- ment susceptibility.
