| 摘 要： | 探究河道水体中浮游动物群落分布的变化及影响因素对河道水体生物多样性的维持和水生生态系统保护具有非常重要的意义。本研究于2017年9月至2018年8月对上海徐汇区代表性的城市河道进行了环境因子和浮游动物群落结构的周年调查，共采集到浮游动物32种，其中轮虫25种，桡足类4种，枝角类3种。全年浮游动物优势种12种，包括轮虫10种，桡足类1种，枝角类1种。不同季节环境因子差异显著，浮游动物种数、丰度和生物量均为夏季最高，冬季最低。浮游动物的典范对应分析（CCA）显示，氮磷比、叶绿素a浓度和溶解氧是影响该水体浮游动物群落差异的显著环境因子。运用水质理化因子、多样性指数及浮游动物优势种进行水质污染水平评价，判断该河流水质状况属于中污型。调查结果可为上海市城市河道生态环境保护提供理论支撑。

| Abstract: | It is very important to study the changes and influencing factors of zooplankton community distribution in river water bodies to maintain the biodiversity of river water bodies and protect aquatic ecosystems. From September 2017 to August 2018, environmental factors and zooplankton community structure were investigated in the representative urban river channel of Xuhui, Shanghai. During this survey, we collected 32 species of zooplankton, including 25 species of rotifers, 4 species of copepods, and 3 species of cladocerans. There are 12 dominant species of zooplankton throughout the year, including 10 species of rotifers, and 1 species in each of copepoda and cladocera. The environmental factors vary significantly in different seasons. The zooplankton species, abundance and biomass are highest in summer and lowest in winter. The canonical correspondence analysis (CCA) of zooplankton and environmental factors showed that the ratio of nitrogen to phosphorus, chlorophyll-a concentration and dissolved oxygen are significant environmental factors that affect the differences of zooplankton communities in this water body. By using water quality physical and chemical factors, diversity index and dominant zooplankton species to evaluate the water pollution level, we concluded that the water quality of the river belongs to the middle pollution. The results can provide theoretical support for urban river ecological protection in Shanghai. |
