Abstract: To understand the structure of aquatic community and the status of ecological environment in Jixi wetland, Jinan City, the plankton species was investigated from January to December 2021 in Jixi wetland, the environmental factors and their influential effects were also analyzed at the same time. The results showed that a total of 66 zooplankton species belonging to 4 categories were identified with the average density of zooplankton was 181.8 ind./L. The dominant species was identified as rotifera accounting for 56.06%.The identified zooplankton could be divided into 7 functional groups, of which the RF group was the representative functional group. A total of 180 taxa belonging to 8 phyla of phytoplankton species were collected with Chlorophyta as the dominant species (accounting for 40.56%), the average density of phytoplankton was 1 052.2×104 cells/L. The phytoplankton community could be divided into 29 functional groups, of which the MP, J, L0, D and X1 groups were identified as representative functional groups. The mean value of Shannon-Wiener diversity index (H′) of zooplankton and phytoplankton were 2.504 and 2.828, respectively, and the average Pielou evenness index (J) value of zooplankton and phytoplankton were 0.708 and 0.722, respectively. The water quality evaluation results showed that the water quality of Jixi wetland was at the middle trophic level, and water body was slightly polluted. Redundancy analysis (RDA) between plankton and environmental factors showed that WT, COND and were the main factors driving spatial and temporal distribution of phytoplankton community in Jixi wetland (P<0.05). The results of this study showed that there are season and space specific variations of composition and biological density of plankton in Jixi wetland, and the water of Jixi wetland was at the middle trophic level.
