In this paper, in order to study the community structure characteristics of zooplankton in the retired farmland wetland of Naoli River Nature Reserve, 18 sampling sites were selected in summer (July) and autumn (October) of 2020, respectively for sampling identification and detection, and the community structure, diversity and spatial and temporal differences of zooplankton in Naoli River Nature Reserve were analyzed and discussed. A total of 163 species of zooplankton were identified, including 123 species in summer and 114 species in autumn, among which there were relatively many species of rotifers. There was no significant difference in species composition and species number of zooplankton between summer and autumn. The dominant species were slightly different in different seasons, and the spatial and temporal differences in abundance were large. The average abundance of each converted wetland type was higher in autumn than展开更多
