Abstract

【Objective】 Vegetation is a vital component of the lake shore zone ecosystems. A comprehensive analysis of plant community composition and diversity characteristics is essential for evaluating the ecological health and service functions of the lake shore zone of Taihu Lake. 【Method】We systematically investigated the plant community around the lake shore zone of Taihu Lake using a transect-quadrat survey method to analyze the species composition and diversity. 【Result】(1) The lake shore zone harbored 226 plant species from 179 genera and 76 families, predominantly wetland and aquatic herbaceous plants. Alien invasive plants were numerous and widely distributed. (2) Distinct, regionally characteristic plant communities formed based on habitat conditions, each containing at least one alien invasive species. (3) The important value of the dominant alien invasive species (ranked by the highest important value, IV) exhibited a negative correlation with the plant community’s diversity index. 【Conclusion】Alien plant invasion poses a serious threat to the lake shore ecosystem of Taihu Lake, undermining biodiversity stability. Enhanced monitoring and management are urgently required.

Key words
