The vegetation and soil conditions of wetlands are important sources of nutrients for lake water, and they form the fundamental basis for the ecological services provided by wetlands. In this study, an investigation was conducted on the plant diversity and soil environmental factors in Caohai lakeside wetland. The following results were obtained: a total of 166 species of aquatic plants were found in the protected area, with the highest number of species belonging to hygrophytes. The families with the highest number of plant species were Asterzceae with 26 species and Poaceae with 25 species. There were differences in plant diversity indices among the sampling sites, with the highest Shannon-Wiener index found in the Loulaoshan site, the highest Simpson index found in the Xihai Matou site, and the highest Pielou evenness index found in the Jiangjiawan site. Monte Carlo tests showed that the soil environmental factors significantly influencing the characteristics of wetland plant community diversity were oxidation-reduction potential (ORP) (40.5%, F=23.2, P=0.002), compaction (6.7%, F=4.2, P=0.012), and temperature (5.4%, F=3.6, P=0.022).
