Plankton Community Structure and Water Quality Evaluation in Upper Changjiang River
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
