Abstract:This investigation was conducted to estimate sand dune movement in Yulin and Jinbian areas of northern Shaanxi Province,China,Results indicate that total sand movement has been 24.433,21.147t for Yulin and Jinbian,respectively.The mean sand dune movement equates to a rate of 4.61 and 3.99m per year,but average monthly sand dune movement rates were 1.152 and 0.997m for the two locations respectively.The rates of movement occurred in Jul.follwed by Jun.,Aug.and Sep..Rates of movement depend on wind velocity,dune height,and dune length and slope ratio.The study reveals that cultivated lands extended obliquely to the direction of sand dune movement are extremely affected severely by the movement,while cultivated land segments extending parallel to the direction of movement are not affected.
