In this study, the evolution process of aeolian dune fields in grassland is numerically investigated. The influence of overgrazing on vegetation coverage, wind erosion of soil and vegetation burial are considered. Results show that evolution time, grazing area and grazing intensity per unit area have significant impacts on grassland desertification. A formula describing the desertification intensity with respect to grazing area and grazing intensity per unit area is given.
► The comprehensive scale-coupled model of dune field in grassland was established. ► The formation and development process of grassland desertification was analyzed. ► Equation of desertification intensity was given. ► The appearance of sand dunes will accelerate the grassland desertification.
