Abstract: Natural plants distributed in the interdune of Taklimakan Desert belong to 9 families,12 genera and 12 species,in which perennial herb accounts for 50% and the floristic elements of constructive species are dominated by Tarim endemic species.The majority of the plants are of small seeds trasported by wind,and possess strong ability of root shooting.The plant community can be divided into 4 formations and 9 associations.The communities of perennial herb are characterized by consociation with single synusia consisting of pure population,and the structure of bush community appear looser.With the movement and burial of mobile dune,plant communities grow constantly in the interdune depressions.

Key words: Taklimakan Desert, Flora, Plant community
