摘　　要：2003年3月和4月,对拒马河(北京段)的原生动物及底栖动物群落结构和物种多样性进行了调查分析,并且就其水质现状及水生动物种类和数量变化对环境污染的指示意义加以探讨。共鉴定出原生动物125种,底栖动物17种。结果表明,拒马河水生动物种类较为丰富,物种多样性高,水质生物指标综合评价拒马河水体受到轻度和中度污染。此外,通过对软体动物、环节动物、水生昆虫在不同站点分布的差异分析,表明河流水体污染可导致底栖动物多样性明显降低。从水生生物指示种的变化,可预测水质的变化。The community structure and biodiversity of protozoa and zoobenthos in Juma River were studied in March and April 2003. Totally, 125 species of protozoa and 17 species of zoobenthos were reported in this paper. The current water quality and the indications of protozoa and zoobenthos to contamination were also investigated. The results showed that species biodiversity of protozoa and zoobenthos in Juma River is high. The water quality is contaminated infrequently. Ecological characteristics of environmental indicators were also discussed. It is able to predict the trends of water qualitative in the river by the variation of the biological indicators.
