Abstract:

In order to clarify the relationship between alien invasive plants and diversity of native plant in typical wetlands in the Yangtze River and its southern regions in Jiangsu Province, the typical wetlands in Taihu Lake and Shijiu Lake were selected as the research areas for plant investigation, and the correlation between the richness of alien invasive plants and the richness of native plants, as well as the invasion coefficient of alien invasive plants and the diversity of native plant species were analyzed. The results showed that a total of 625 species of higher vascular plants were found in the survey, including 28 species of invasive plants belonging to 21 genera and 12 families. Among them, Compositae was the dominant family, with the majority being annual herbs. Solidago canadensis and Veronica persica had a high frequency of invasion and a wide distribution. Coreopsis basalis and Chenopodium glaucum had the greatest dominance. The alien invasive plants in the study area significantly reduced the diversity of native plants, and the invasion coefficient of alien invasive plants was significantly negatively correlated with the richness, the Shannon-Wiener index, the Simpson index, and the Pielou index of native plants(P < 0.05).
