| 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 tOsorting and their spatial relations. The sand samples studied are collected from the oases in the southernmargin of the Taklimakan Desert. The aims are to make clear the properties of sand materials and thecondition of wind action, to analyse the movement of blown sand and the formation of blown sandlandforms, thus laying a basis for building the protective system of oases. |
