摘要
为了解长江河流域浮游生物群落结构,评价水生态环境质量,于2021年9月对长江河上游典型区段15个采样站点的水体理化性质和浮游生物群落现状进行调查,分析浮游生物群落结构组成,并开展流域水质状况评价.结果表明,长江河上游监测到浮游植物共68种,隶属于6门43属;浮游动物共15种,其中轮虫类12种、枝角类2种、桡足类1 种.基于水体理化参数与浮游生物学评价表明,长江河上游整体水质处于Ⅱ～Ⅲ类,为中污染状态.
Abstract
In order to understand the structure of the plankton community,evaluate the water ecological environment quality,the physical and chemical properties of the water body and the status of the plankton community of 15 sampling sites in typical sections of upper Changjiang Riv-er in September 2021 were investigated,the composition of the plankton community structure was analyzed and the water quality status of the basin was evaluated.The result showed that 68 species of phytoplankton were detected in upper Changjiang River,belonging to 43 genera and 6 phyla.There were 15 species of zooplankton,including 12 species of Rotifera,2 species of Cladocera and 1 species of Copepoda.Based on the physical and chemical parameters of water quality and plankton biological evaluation,the overall water quality of upper Changjiang River was in class Ⅱ-Ⅲ,which was in the state of medium pollution
