Abstract: This paper, through the characteristic analysis of sediment grain size, discussed the grain size parameters of sands in semi-covered sand barrier and shifting sand areas along the oil-transporting highway in Tarim Desert, and pointed out that with time went by, the mean diamter of sand in barrier area will become finer, but sorted badly, the changes of skewness and kurtosis are not evident. The cumulative probability curve exhibits 4~6 sections, including two suspension components; saltation components constitute the main sand materials that cover the barriers; Also were discussed the grain size composition and the movement of blown sand, thus laying a basis of grain-size parameters for building and repairing sand barriers.
