淮南高塘湖浮游甲壳动物群落结构特征
Community Structure of Crustacean Zooplankton in Gaotang Lake, Huainan

在淮南高塘湖湖心设置采样点，从2016年12月至2017年11月每月中旬采集水样进行鉴定分析。结果表明：鉴定出浮游甲壳动物共10属18种。枝角类6属8种，年生物总量为0.4 mg/L，年总丰度为48.8 ind./L。桡足类4属10种，年生物总量为0.55 mg/L，年总丰度为26.6 ind./L，枝角类丰度较高，但生物量较低；浮游甲壳动物的优势种有8种，其中优势度最高的有3种浮游甲壳动物，分别是简弧象鼻溞、秀体溞属和剑水蚤幼体。枝角类浮游甲壳动物从春至冬生物量不断减少，在春季有最大值，冬季没有枝角类。桡足类生物量与枝角类正好相反。
Sampling points were set in the center of Gaotang Lake in Huainan, and water samples were col-lected from December 2016 to mid November 2017 for identification and analysis. The results showed that 18 species of crustacean zooplankton belonging to 10 genera were identified. Cladocerans belong to 6 genera and 8 species, with an annual biomass of 0.4 mg/l and a total annual abundance of 48.8 ind./L. Copepods belong to 4 genera and 10 species, with annual biomass of 0.55 mg/l and annual total abundance of 26.6 ind./L. Cladocera abundance is high, but biomass is low; There are 8 dominant species of planktonic crustaceans, among which 3 species of planktonic crustaceans have the highest dominance, namely, Bosmina coregoni, Diaphanosoma sp. and Thermocyclops spp. The biomass of Cladocera planktonic crustacean decreased continuously from spring to winter, and reached the maximum in spring, but there was no Cladocera in winter. The biomass of copepods is opposite to that of Cladocera.
