    Abstract:

    [Objective] Based on previous research of wind erosion and deposition in oasis-desert zone, we aimed to explore the influences of Alhagi sparsifolia stumping and topography on sand surface erosion and deposition in Cele County of Xinjiang Uygur Atonomous Region.[Methods] Erosion pins were used and topographic surveys and wind velocity observations were conducted.[Results] The surfaces of stumping belts and reservation belts were dominated by wind erosion due to the large decreasing of vegetation coverage at the beginning of A. sparsifolia stumping in spring. Wind deposition occurred on the surfaces of A. sparsifolia quadrates due to the increased vegetation coverage in summer. Slight wind erosion mainly occurred on the surface with sparse vegetation and low topographic position. In autumn, as the vegetation coverage on the land surface maintained maximum and stable, wind erosion and deposition decreased, and the sand surface was dominated by wind deposition.[Conclusion] A. sparsifolia stumping with width of 4 m and 3 m for stumping belt and preserving belt, respectively, may not effectively prevent wind erosion in spring, but can effectively prevent wind erosion in summer and autumn.
