Ecological environment of Xilingol grassland are fragile and unstable and the desertification are widely distributed in this area. Took Xilingol grassland desertification as the object of this study, we has carried on hazard assessment on disaster-pregnant environment of desertification in Xilingol Grassland by using remote sensing technology and GIS technology and related mathematical statistics methods. The result showed that the hazard of disaster-pregnant environment in Xilingol grassland is high in the west, low in the east and area of moderate hazard is largest. Extremely low hazard areas, low hazard areas, moderate hazard areas and extremely high hazard areas have changed into high hazard areas in the study. The hazard of disaster-pregnant environment of desertification Xilingol grassland and the degree of desertification are almost the same in Xilingol grassland.
