Abstract:: The paper used six sets of the multi-temporal remote sensing data of Duolun county of Inner Mongolia,acquired in aerial photo of 1960,1975 and Landsat TM images of 1987,1995,2000,2005.The desertification data base was set up and the temporal and spatial variation of land desertification was analyzed by extraction of land desertification information and overlay analysis other data on research area.The results showed that the desertification area in1960-1995 increased by 639.88km²,and reduced by 427.18km² during 1995-2005.From 1960 to 1995,the extension area of desertification mainly occurred on two sides of three sand belts.Owing to the deforestation for land reclamation,grassland overload,the desertification area was extended.Between 1995 to 2005,the area of desertification decrease mainly distributed in south belt region of country and Huangliu area.Since the implementation of‘the Beijing-Tianjin dust storms sources control project’,‘the project of withdrawing graze and returning to grassland’,‘banning herd and confinement feeding project’and‘eco-migration project’,the desertification area in Dolonnur county reversed quickly,most of the mobile dunes were stabilized and the total area of desertification gradually reduced,obviously in the south sand belt of research area.
