Abstract: Survey on invasive plants in riparian zone of Gan River was conducted on the basis of three aspects of river basin, vegetation community and interference manners.There exists 31 species of invasive plants belonging to 27 genera in 17 families.Among them, Compositae is the most consisting of 9 species.There is not significant difference in the dominance of invasive plants among up-, mid- and downstream of riparian zone in Gan River.However, the distribution of invasive plants has been significantly effected by vegetation types in the riparian, e.g., the dominances of invasive plants in herbosa and shrub are significantly greater than in high-forest community.The interference positively impacted the distribution of invasion plants;the significant difference for the dominance of invasive plants was observed in with and without inference, but no in different inference manners.
