【Aim】 In order to fully understand the species composition, origin, life form, and floristic composition of alien invasive plants in various habitats in Changde and to protect the local ecosystems. 【Method】 Twenty-two types of habitats and 9 types of land use in Changde were investigated, and field investigations were carried out by standard sampling method, sampling method and line sampling method. 【Result】 There were 104 species of alien invasive plants in the Changde area, belonging to 31 families and 77 genera, of which Compositae (29 species), Amaranthaceae (9 species), Leguminosae (8 species), and Gramineae (8 species) were the dominant families, accounting for 52% of the total species. The genus with the most species was Amaranthus spp. (5 species). Accounting for 65.4% of the total species, 68 alien invasive plants originated from the Americas. Herbaceous plants included 97 species and account for 93.3% of the total number of species. The results of flora analysis showed that the main distribution types of alien invasive plant families in the Changde area were of worldwide, and pan-tropical origins with some from tropical Asian and American regions. 【Conclusion】 The increasing number of alien invasive plants in the Changde area is related to its economic development in recent years and its geographical location. Relevant functional departments should pay close attention to this issue and implement timely and effective prevention and control measures.
