摘要: 调查研究表明:塔克拉玛干沙漠腹地非河流影响区域,天然植物隶属于9科、12属、12种。生长型以多年生草本为主,占50%。建群种植物区系以塔里木特有种为主。绝大多数植物为风媒植物,根蘖能力很强。植物群落分为4个群系、9个群丛。多年生草本群落常由纯种群构成单优群落,灌木群落结构松散。随着沙丘的移动与掩埋,植物群落周而复始的生存于丘间地。

关键词: 塔克拉玛干沙漠, 植物区系, 植物群落

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
