Land Desertification Trend Research Based On Remote Sensing Technology

With the rapid development of economy,under the joint action of natural and man-made,desertification become nowadays one of the most serious environmental problems,has seriously affected and threaten the normal human production and living and survival environment.Inner Mongolia autonomous region is one of the provinces affected by desertification.In order to prevent desertification and change the ecological environment of the autonomous region,it is necessary to have scientific and accurate understanding of the occurrence and development of desertification,and to grasp the characteristics of spatio-temporal dynamics of desertification and provide scientific basis for comprehensive treatment and prevention.The wide distribution of land desertification in Inner Mongolia area,types,intensity big,including sandy desertification water erosion and desertification saline desertification types mainly sandy desertification;Desertification in the autonomous region was a deteriorating trend from 1975 to 2000,and the trend of improvement was between 2000 and 2016;La shan plateau desertification area,ordos plateau drought desertification area,desertification in eastern Inner Mongolia plateau area,the desertification area of the songliao plain is the most concentrated distribution of land desertification in Inner Mongolia region,Alashan area is the most serious,the second is the ordos area.In order to discuss the distribution of land desertification in the Inner Mongolia autonomous region in the last 40 years of the land,it's a data source of the data from 1975,2000,2016,in the three stages of the remote desertification of the land,and by using telemetry to interpret the image,it is based on the fact that the land desertification in the autonomous region and the area and the area of the land,it is based on the fact that the land of desertification,the landscape of the land,the change of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the conditions of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,he changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the changing of the land,the conditions of the desertification.
