Abstract: The Houshan area, where many aeolian landforms developed widely, is located in south part of stepped upland plain of Inner Mongolia. It indicated that intensive roughness is the main form of desertification in the region and suriace gravel caused by intensive coarseness is the direction of gebmorphic development after analysing the formative conditions,developmental process and stability of some common aeolian landforms. So far as the development of .regional landforms, the desertification in the region can be considered as expansion of wind erosion Gobi in stepped upland plain which lies to the north of the region,so it can be known as the aeolian Gobi.
