摘要：

2009—2010年对北运河水系浮游动物和水质进行了周年调查，对浮游动物种类组成、密度、生物量、群落多样性和水体理化因子等进行了分析。结果表明：北运河浮游动物有79种，其中原生动物12种，轮虫34种，枝角类23种，桡足类10种；春季、夏季和冬季轮虫数量占优，秋季原生动物数量占优；主要优势种为轮虫、枝角类中的耐污种；北运河的水质普遍较差，主要污染物为总氮、铵态氮和总磷，大于我国地表水环境质量V类标准的212～9.79倍；大部分断面为中度污染，部分断面为重度污染，水质质量在中重污染之间。

Abstract:

In order to protect river environment rationally, we investigated zooplankton and water quality in Beiyun River four times during 2009 and 2010, and analyzed the species composition, density, biomass, diversity index, and water physicochemical character. The results showed that there were 79 species of zooplankton in Beiyun River, including 12 species of Protozoa, 34 species of Rotifers, 23 species of Cladocera, and 10 species of Copepods. Rotifers dominated in spring, summer and winter, while Protozoa in autumn. The dominant species of the zooplankton were Rotifers and pollutiontolerant Cladocera species. The water quality in Beiyun River was generally poor. The total nitrogen, ammonium nitrogen and total phosphorus were the major pollutants in Beiyun River, with their contents 2.12-9.79 times higher than the standards of grade V national surface water environment quality of China. Most of sections in Beiyun River were moderately polluted, some sections were heavily polluted, and the water quality was at the middleheavy pollution level.
