According to two years (2018−2019) spring plankton surveys in the Zhoushan coastal waters, the zooplankton community structure (species composition, abundance of dominant species) were investigated, the canonical correspondence analysis (CCA) was used to study spring interanuual difference of zooplankton community and causes of their dynamics, the mechanism of community dynamics were discussed according to our results.The results show that the study region is divided into three groups according to cluster analysis of sea surface temperature (SST) and sea surface salinity (SSS): Hangzhou Bay water masses (Area I), upwelling water masses in Zhoushan Island (Area II), and water masses in Zhoushan offshore area (Area III). Water mass groups have significant influence on the composition of zooplankton community. The main species contributing to the difference between the three water masses in spring 2018 and spring 2019 (contribution rate >10%) are Calanus sinicus. The contribution species of the same water mass in two years were: Tortanus derjugini (56.91%) and Labidocera euchaeta (12.34%) in Area I, Calanus sinicus (72.64%) and Muggiaea atlantica (13.35%) in Area II, Calanus sinicus (41.93%) and Noctiluca scintillans (22.94%) in Area III. CCA shows that the first CCA axis (CCA1) and the second CCA axis (CCA2) explained 46.14% of the accumulated variance of the dominant species of zooplankton and 97.82% of the species-environment accumulated variance in spring 2018 and spring 2019. CCA1 mainly reflects the spatial difference between the offshore water mass and the Hangzhou Bay water mass. CCA2 mainly reflects the interannual difference between the stations in 2018 and 2019. Salinity is the main factor influencing the spatial difference of zooplankton community structure in spring, while temperature and chlorophyll a concentration are the main factors controlling the interannual difference of zooplankton community structure in spring.
