Abstract：The Aibinur lake region had great position for its ecology and geography.The land desertification in Aibinur lake region was monitored and analyzed based on the RS and GIS with the satellite data.The results showed that the desertification by wind-erosion and saltation have absolute superiority in Aibinur Lake region.According to the analysis of the data in 2000,the area of desertification by wind-erosion occupies 32.35%,the area of desertification by saltation occupies 54.49%,the area of composite desertification occupies 12.68%,and water erosion desertification occupies 0.48%.From 2000 to 2005,the desertification area has reduced 4.5%,the area of desertification by saltation has reduced 2.85%,the area of wind-erosion reduced 41.58%,but the area of composite desertification has increased 82.9%.The degree of desertification tended to heavy in the whole.The time and space distribution changes in Aibinur lake region are that wind-erosion area and saltation area have reduced,the composite desertification area has increased.
