We investigated terrestrial and aquatic ecosystems in Gaoyou County,Jiangsu Province,and analyzed the diversity and floristic characteristics of plant genera at family,genus and species levels.The investigation show that there were 556 species of terrestrial vascular plants,belonging to 128 families and 392 genera,the most of which were rosaceae(38 genera and 59 species),and Polygonum(9 species).There are 45 species of aquatic plants,which belong to 24 families and 37 genera.Gramineae and Potamogeton L.are the most common plants,with 5 species in 5 genera and 5 species in 2 genera respectively.At the genus level,the Potamogeton L.has the largest number of plants,with 4 species.The floristic analysis shows that the continental vascular plants in this region were mainly pantropical and North temperate distribution types,accounting for 43.9% of the total genera(excluding global distribution genera).The aquatic plants are dominated by pantropical species,which account for 64.3% of the total genera(excluding worldwide genera).In general,the floristic characteristics reflect the climatic characteristics of the transition from tropical to northern temperate zone in Gaoyou City,Jiangsu Province.This result enhances the understanding of plant diversity and floristic characteristics,and provides data support for plant resource protection and vegetation restoration.
