摘要
在淮南市淮西湖中设置了采样点,于2016年12月至2017年11月分冬、春、夏、秋四个季节采集浮游甲壳动物样品,分析鉴定其群落结构特征和时空分布特征。结果表明:共检测到浮游甲壳动物7属10种,总密度为23 ind./L,总生物量为0.6 mg/L;其中桡足类数量远超枝角类,以短尾秀体溞、秀体溞属、微型裸腹溞、剑水蚤幼体和近邻剑水蚤为主要优势种,多样性范围在0.9~20.6,均匀度范围在0.5~1。
Sampling points were set up in Huaixi Lake in Huainan City, and samples of planktonic crustaceans were collected in winter, spring, summer and autumn from December 2016 to November 2017, and their community structure characteristics and temporal and spatial distribution characteristics were analyzed and identified. The results showed that 7 genera and 10 species of planktonic crustaceans were detected, with a total density of 23 ind./L and a total biomass of 0.6 mg/L. Among them, the number of copepods far exceeds that of cladocera, and the main dominant species are Daphnia brevicaudata, Daphnia, Daphnia miniata, cyclops larvae and its neighbor cyclops, with diversity ranging from 0.9 to 20.6 and evenness ranging from 0.5 to 1.
