Abstract: The majority of desert highway in Tarim basin passes through the shifting sand areas where wind-sand activities are very violent.So,the establishment of sand barrier systems is very importent.Sand-moving wind velocity and sediment transport strength are the fundmental data in the building of sand barrier systems.This paper,based on the field survey and observation,statistical analysis of sand-moving wind velocity and the numerical calculation of sediment transport strength,pointed out that the more deep to the hinterland,the more northeast by east of sand-moving velocity and the more strong and concentrated of sediment transport.

Key words: Desert highway, Statistics of sand-moving wind velocity, Sediment transport strength
