摘    要:通过对库姆塔格沙漠东南缘天然植被调查结果显示:调查区天然植被以荒漠植被类型为主,在5种植被型23个植被群系中,荒漠植被群系占到52%,表现出植被类型的荒漠特性。荒漠植物群落有经向、纬向和海拔高度变化的分布格局,水分是影响植被径向分布的主要因素,气候则反映了植被纬向和海拔高度分布的变化。同时对主要的典型植物群落的特征进行了分析,为荒漠植被的恢复及其沙漠综合治理提供理论依据。

关 键 词:库姆塔格沙漠  天然植被  植被群落  分布格局

Abstract:Natural vegetation in Southeast edge of Kumtag desert belongs to 5 vegetation types and 23 associations,which are dominated by desert vegetation types,accounting for 52%.Desert plant communities show distributing pattern along with longitude,latitude and altitude;water is the major actor to influence the longitudinal distribution and climate mainly influence the latitudinal and altitudinal distribution.The paper has also analyzed the characters of plant communities so as to provide theoretical base for desert plant restoration and comprehensive desert treatment.
Keywords:Kumtag desert  natural vegetation  plant community  distribute pattern
