Interannual variation of phytoplankton community structure in the Yangtze River estuary
In order to understand the seasonal community structure characteristics of phytoplankton in the Yangtze River estuary and its adjacent waters,a four-season survey and analysis was carried out from April 2021 to January 2023.Research results show that the number of phytoplankton species during the survey period showed obvious distribution differences in different seasons,namely winter(135 species)＞spring(83 species)＞autumn(81 species)＞summer(64 species).Skeletonema costatum was the absolute dominant species in all seasons.Analysis of the seasonal distribution of cell abundance found that summer had the highest cell abundance,followed by spring,autumn,and winter.In the diversity index analysis,the diversity in summer was significantly lower than in other seasons,indicating that the community structure in summer was relatively simple.
