摘要/Abstract

摘要： 2013年8月、10月和2014年1月、4月对湖北金沙河水库浮游动物群落结构进行了调查。共鉴定出浮游动物95种，其中原生动物45种，轮虫40种，枝角类7种，桡足类3种；浮游动物密度范围为4939.9～27238.1 ind·L^-1，生物量变化范围为0.56～1.49 mg·L^-1；金沙河水库浮游动物数量以原生动物和轮虫占优势；将金沙河水库浮游动物优势种类和经Pearson相关性分析筛选出的环境因子进行冗余分析，筛选的环境因子中PO₄^3--P和COD是影响浮游动物群落结构的主要环境因子；金沙河水库夏、秋季多样性指数较冬、春季高，而4个季节浮游动物物种分布较均匀。

Abstract: Zooplankton samples were collected in August and October of 2013, and January and April of 2014 in the Jinshahe Reservoir. A total of 95 zooplankton species were recorded, consisting of 45 protozoan, 40 rotifers, 7 Cladocera, and 3 Copepoda. The density of zooplankton varied between 4939.9 and 27238.1 ind·L^-1 and the biomass of zooplankton ranged from 0.56 to 1.49 mg·L^-1. Zooplankton in the Jinshahe Reservoir was dominated by protozoan and rotifer. Correlations between the dominant species of zooplankton and environmental factors which were screened by Pearson analysis were calculated using redundancy analysis, and the results suggested that the community structure of zooplankton could be significantly influenced by PO₄^3--P and COD among the selected environmental factors. The species diversity index was higher in summer and autumn than in spring and winter, but evenness index showed uniform distribution of zooplankton among the four seasons.
