Abstract：Located in Jiacuoxiong Township,Sangzhuzi District,Shigatse City,Xizang,Jiangsa National Wetland Park is composed of the Nianchu River and forest areas on both sides,mainly protecting the wetland ecosystems,with a planned area of 1827.78 hectares.In this study,a combination of transect and quadrat was used to investigate and study the wild plant resources in the wetland park.The results showed that(1)the typical plant communities in the wetland park included arbor forest,shrub forests or shrubs,aquatic and swamp plant communities;(2)the main vegetation of the wetland park can be divided into 6 vegetation types,9 flora groups and 26 plant formations;and the vegetation types include aquatic vegetation,swamp vegetation,swampy meadow vegetation,bushwood,brush mead-ow,and wetland woody vegetation;(3)there are 44 families,110 genera and 164 species of vascular plants in the wet-land park;(4)among the distribution area types of plant families,the number of widely distributed families in the wold is the greatest,accounting for 61.90％;the dominant families are Asteraceae(18 species),Poaceae(18 species),Ranunculaceae(11 species),and Fabaceae(13 species);(5)among the distribution area types of plant genera,the northern temperate zone has the largest number of genera,accounting for 43.52％,followed by the world's widely distributed genera,accounting for 26.85％;and the dominant genera are Populus(2 species)and Salix(4 species).The investigation and research results can provide a reference for the protection,utilization,planning and construction of wild plant resources in the wetland park.
