- We interpreted of Landsat TM remote sensing images of 1980, 1990, 2000 and 2013 of Naiman Banner and obtained the different degrees of desertified land area in different times. The results show that the aeolian desertification in Naiman Banner experienced a process of reversion, development and reversion during 1980-2013. In 1980-1990, the aeolian desertification reversed, the area of desertified land reduced 207.58 km2. In 1990-2000, the aeolian desertification developed, the area of desertified land increased 60.25 km2. In 1990-2000, the desertification shows apparently reversal, increased by a total of 671.62 km2. In the space, aeolian desertification expanded to the northwest, and the land distributed in central and the middle-east of study area began to develop into desertified land during 1980-1990. In 1990-2000, aeolian desertification in northern begun to reverse, but in the central region, the desertified land begun to increase. And in 2000-2013, the desertified area in central region reversed to the non-desertified land, and most of the land is converted to low-grade.
