We systematically elaborated and compared the spatial scope and landscape changes of Horqin Grass-land and Horqin Sand Land from their definitions and ranges.Horqin Grassland is an area with geographical units named after Mongolian tribes,but the boundary is unclear.Horqin Sand Land is also an area that borrows tribal names,but has independent topographic and geomorphic units,and clear boundaries.Horqin Grassland and Horqin Sand Land belong to two spatial regions that are both cross and different.The area and range of Horqin Grassland are larger than that of Horqin Sand Land which has obvious regional characteristics,and is a typical and research object area to study the development and restoration of aeolian desertification.Based on those cognition,we summa-rized the technologies and example models of comprehensive land management and desertification controlling over the years,and finally sorted out what should be focused on in the future to serve the annihilation war against deser-tification for Horqin Sand Land.
