Using the TM-5 remote sensing data in 1990 and 2011 in Jinghe watershed, a model to remote monitor desertification under the Albedo-NDVI scatter plot of Jinghe watershed was built based on desertifition difference index(DDI). The results showed that the desertification degree became severity from 1990 to 2011 and the predominant natural factors were the annual evaporation and temperature. Moreover, there are many potential risks of wind-erosion desertification in study area. Although the active steps taken by government were counterbalancing desertification caused by climate change in recent years, the reversion of desertification was slowed down by the population pressure, the inefficient utilization of water resources, and human dimensions which needed to be overcome in the prevention and control of desertification in Jinhe watershed in the future.
