Abstract: Inner Mongolia municipality,lying in the North China, is one of the zones with strong wind erosion and rapid land-use changes. It covers the grassland- cropland tran sition zone and the over-grazing grassland. The degraded grasslands, deserted croplands and dry-farming croplands of Inner Mongolia were the source regions of dust-storm which affected North and East China,Korea, Japan and America in 2000. Based on 2 sets of land-use data and the correspondent wind erosion data, the static spatial distribution and the dynamic spatial changes are outlined.According to the features of static and dynamic spatial distributions, the sub-regions of Inner Mongolia are divided. The details about the land-use dynamics and wind erosion dynamics are discussed in each specific sub-region,and the driving- droved relationship between the two dynamics is then analyzed. It can be inferred that the basic patterns of both land-use and wind erosion in Inner Mongolia did not change greatly during late 1990s. However, the main types of land-use changes are degradation of grasslands and the expansion of croplands, and the wind erosion is intensified in general. The degradation of grasslands and the expansion of croplands caused obviously intensified wind erosion, while the amendment of grasslands and the shrink of croplands affected wind erosion slightly, all of which show that there exist non -balanceable influences on wind erosion caused by different land-use change orientation.

Key words: dynamic change, Inner Mongolia, land-use, wind erosion
