摘要
本次研究于2018年9月进行,共鉴定出浮游动物41种,其中原生动物10种,轮虫20种,枝角类5种,桡足类6种。物种数量最多的是4#采样点(21种),最少的是1#采样点(9种)。丰度波动于1023.95个/L^21,750.10个/L之间,生物量在0.29 mg/L^2.21 mg/L之间。浮游动物以轮虫为主,且轮虫优势种中大部分为耐污种,表明水体受到污染。从优势种来看,泰湖国家湿地公园秋季水体为中–富营养型。
In September 2018, 41 species of zooplankton were identified, including 10 protozoa, 20 rotifers, 5 Cladocera and 6 Copepoda. The largest number of species was S4 (21 species), and the smallest was S1 (9 species). The abundance fluctuated from 1023.95 ind./L to 21750.1 ind./L and biomass from 0.29 mg/L to 2.21 mg/L. The zooplankton composed mainly by rotifers, and most of the dominant species of rotifers are pollution resistant, indicating that the water body was polluted. In terms of dominant species, the water body of Tai Lake National Wetland Park in autumn was medium eutrophic.
