摘要: 2016年对上荷塘水库的浮游动物群落进行逐季度调查,分析上荷塘水库浮游动物的种类组成和季节变化,并探讨浮游动物群落结构与环境因子的关系。调查共观察到浮游动物19属29种。主要优势种为暗小异尾轮虫(Trichocerca pusilla)、裂足臂尾轮虫(Brachionus diversicornis)和广布多肢轮虫(Polyarthra vulgaris),且优势种的季节性变化明显。浮游动物的年均密度和生物量分别为(1 225.88±1 572) ind./L和(0.340±0.415) mg/L,密度和生物量的季节性变化显著。均匀度指数(J)和Shannon-Wiener指数(H')均为秋季最高。典范对应分析表明,水温、透明度和pH等理化环境因子是影响上荷塘水库浮游动物群落结构的主要因素。

Abstract: The quarterly investigations were carried out on zooplankton community in Shanghetang reservoir in 2016. The species composition and seasonal changes of zooplankton in the Shanghetang reservoir were analyzed. The correlation between the zooplankton community structure and the environmental factors was discussed. A total of 19 genera and 29 species of zooplankton species were observed. The dominant species, average density and biomass of zooplankton community displayed obvious variation with season. Dominant species in the Shanghetang reservoir were Trichocerca pusilla, Brachionus diversicornis and Polyarthra vulgaris. The average annual values for zooplankton density and biomass were (1 225.88±1 572) ind./L and (0.34±0.415) mg/L, respectively. The species richness index(J) and Shannon-Wiener index (H') also showed obvious seasonal variations, with the highest values both in autumn. From the result of canonical correspondence analysis, environmental factors such as water temperature, SD and pH affected the composition and the density of zooplankton community.
