With the aid of the remote sensing technology, the land use/cover change data between 2001 and 2010 were obtained. We selected a type of the MODIS global land cover products, the IGBP product, through compare the MODIS global land cover products on the accuracy from the aspect of quantity precision products, taking the 30-m Global Land Cover Dataset as reference data. The spatial and temporal characteristics of the Mongolian Plateau were revealed by analyzing the changing process. The results indicated that the structure of land use in the Mongolian Plateau has an obvious change over that period. In particular, the area of cultivated land and desert decreased while the grassland and forest expanded significantly. The spatial pattern of the land cover change, which is from 2001 to 2011 was gained and we found that the intensity of variation ranged with locations. The northland has a more serious change than southland. Similarly, the eastern region has experienced a greater change than the western, especially in the pediment plain of northeast regions. In conclusion. the land use pattern in Mongolian Plateau has become better over the ten years.
