摘　　要：2013年5～6月对泾河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47种（属）,平均密度为238.8 ind/L,平均生物量为18.98×10-3 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,容易受到外界的干扰.The zooplankton community composition were investigated in Shanxi section of Jing River from June to July in 2013.The results showed that：47 species （genera）,3 phylum of zooplankton were observed in the whole paragraph.The average density was 238.8 ind/L; the average biomass was 18.98 × 10-3mg/L.The comprehensive index of plankton in Jing River showed that the composition and structure of community was instability,so,the zooplankton community composition was interfered by external environment susceptibility.
