摘要
2004～2006年对北京地区白河和温榆河浮游生物群落进行调查。结果显示:白河浮游动物137种,隶属于78个属,其中原生动物最多,共计73种,其次是轮虫55种,枝角类7种,桡足类2种;温榆河浮游动物135种,隶属于83个属,其中原生动物共计65种,轮虫类53种,枝角类13种,桡足类4种。两河浮游动物种类组成大部分相同,以原生动物为主,但两河大型浮游动物的种类组成差别较大。据两条河流浮游动物的生态状况和调查结果综合分析,白河的水质较好,多数站点水体清洁,只有少数站点水体达轻度污染,温榆河水质较差,大多数站点水体属轻度污染,个别站点属中度污染。
The zooplankton composition and distribution in Baihe River and Wenyuhe River in region of Beijing were investigated. Total 137 species, 78 genera of zooplankton were observed in Baihe River. Among them, 73 species of Protozoa are the most. The next in order are 55 species of Rotifera, 7 species of Cladocera, 2 species of Copepoda. Total of 135 species, 83 genera of zooplankton were observed in Wenyuhe River. Among them, 65 species of Protozoa are the most. The next in order are 53 species of Rotifera, 13 species of Cladoeera, and 4 species of Copepoda. The ecological system of zooplankton in the two rivers provides biological and theoretic basis for monitoring and reforming river water quality in Beijing by biodiversity indices.
