摘      要：Studies of wind erosion based on Geographic Information System（GIS） and Remote Sensing（RS） have not attracted sufficient attention because they are limited by natural and scientific *** studies have been conducted to estimate the intensity of large-scale wind erosion in Inner Mongolia,*** the present study,a new model based on five factors including the number of snow cover days,soil erodibility,aridity,vegetation index and wind field intensity was developed to quantitatively estimate the amount of wind *** results showed that wind erosion widely existed in Inner *** covers an area of approximately 90×104 km2,accounting for 80% of the study *** 1985–2011,wind erosion has aggravated over the entire region of Inner Mongolia,which was indicated by enlarged zones of erosion at severe,intensive and mild *** Inner Mongolia,a distinct spatial differentiation of wind erosion intensity was *** distribution of change intensity exhibited a downward trend that decreased from severe increase in the southwest to mild decrease in the northeast of the *** occupied by barren land or sparse vegetation showed the most severe erosion,followed by land occupied by open *** would have the most dramatic potential for changes in the future because these areas showed the largest fluctuation range of change *** addition,a significantly negative relation was noted between change intensity and land *** relation between soil type and change intensity differed with the content of Ca CO3 and the surface composition of sandy,loamy and clayey soils with particle sizes of 0–1 *** results have certain significance for understanding the mechanism and change process of wind erosion that has occurred during the study ***,the present study can provide a scientific basis for the prevention and treatment of wind erosion in Inner Mongolia.
