摘要: 运用沉积物的粒度分析方法,研究了塔克拉玛干沙漠南缘绿洲不同类型沙样的粒度参数、粒度频率分布、平均粒径对标准差特性图等粒度特征及其空间关系,为查明沙源物质的性质和风力作用状况,分析风沙运动及风沙地貌形成,建立绿洲防护体系提供依据。

关键词: 塔克拉玛干沙漠, 绿洲, 沙物质, 粒度特征

Abstract: This paper,through the characteristic analysis of sediment grain-size, discuss the grain-size parameters,the frequency distributions of grain-size, the response diagram of mean grain-size to sorting and their spatial relations. The sand samples studied are collected from the oases in the southern margin of the Taklimakan Desert. The aims are to make clear the properties of sand materials and the condition of wind action, to analyse the movement of blown sand and the formation of blown sand landforms, thus laying a basis for building the protective system of oases.

Key words: Oases, Taklimakan Desert, sand material, Grain-size charateristic
