Abstract: Field surveys were carried out on vascular plant in Fuxian Lake National Wetland Park, Yunnan province from 2017 to 2019. The result showed that there were 470 species of 128 families and 316 genera. At the family level, small and medium families constituted the main part in the park, while 9 large and larger families represented by Leguminosae, Compositae and Poaceae were dominant families. Main distribution types were Pantropic and Cosmopolitan. At the level of genera, Pantropic and north accounted for 19.7% and 13.5% of the total genera. The composition of plant distribution types in Fuxian Lake National Wetland Park indicated the abundance of plant resources, the diversity of life types, and the distribution characteristics of tropical family, genus and species.
