Abstract Clipping has been one of the most dominant utilization of Alhagi sparsifolia in the Cele desert-oasis transition zone. We examined the capacity of Alhagi Sparsifolia for trapping blow sand and sandy soil properties under different clipping disturbances. The results indicated that the capacity of plant for trapping blow sand and vegetation restoration of clipping in fall were superior to in spring. Comparing with the control, both Clipping in spring and in fall decreased the bulk density of surface layer. The soil porosity of surface layer under the clipping in fall had improved by 2.5 percent more than of that clipping in spring. Both clipping in fall and in spring had increased the concentrations of organic matters and total nitrogen in the soils of surface layer under the canopy of shrubs, but exhibited no significant change in the contents of total phosphorus and total potassium. In contrast, clipping in fall developed more easily a "fertile island" and so were capable of recovering the functions of desert steppe ecosystem after 4 years.
