| 探究城市河道水体中浮游动物群落分布的变化及影响因素，为城市河流的水质评价和生态监测提供理论支持，并为城市河流生态修复和河道生态环境保护措施的制定提供基础数据。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。环境因子的季节变化导致浮游动物差异显著，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研究河道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，该河流水质状况属于中污型。 |

| To maintain the biodiversity of water bodies and protect aquatic ecosystems, it is important to study the changes and driving factors of the zooplankton community in rivers. In this study, zooplankton community structure and environmental factors in a representative urban river channel of the Xuhui district in Shanghai were monitored from September 2017 to August 2018. Based on the monitoring results, the relationship of the zooplankton community to the environmental factors was examined. We aimed to provide theoretical support for water quality evaluation and ecological monitoring and restoration of urban rivers in Shanghai. During this survey, a total of 32 zooplankton species were collected, including 25 rotifer species, 4 copepod species and 3 cladoceran species, accounting respectively for 78.1%,12.5% and 9.4% of the total species. There were 12 dominant species of zooplankton through the year, including 10 rotifers, 1 copepod and 1 cladoceran. Zooplankton species richness was highest in summer (18 species), followed by autumn (17 species), spring (12 species) and winter (5 species). The environmental factors varied significantly by season, resulting in significant seasonal differences in zooplankton community structure. Zooplankton species richness, abundance and biomass were all highest in summer and the lowest in winter. The Shannon-Wiener diversity (H'), Margalef richness （D）and Pielou evenness (J' ) indices of the zooplankton community were in the respective ranges of 1.40-2.49, 0.64-2.16, 0.72-0.88, with significant seasonal differences in diversity and richness (P<0.001), but variation in the evenness of the zooplankton community was not evident. Canonical correspondence analysis (CCA) of zooplankton and environmental factors showed that the ratio of nitrogen to phosphorus, chlorophyll-a concentration and dissolved oxygen were the significant environmental factors. Finally, water pollution in the river was evaluated using a combination of physical and chemical water quality parameters, diversity indices and dominant zooplankton species, and the results indicate moderate pollution. |
