Abstract
Desert environment has the characteristic of being further deterioratedand some non-desertified land has changed into desertified one in Xinjiang. The main styles of deseritfication are: dunes activated, wind-sand current and moving dunes get into the non-desertified land, under the action of wind, form wind erosion and shifting sand land.
According to the degrees of mobile dunes and wind-sand current and to the coverage of vegetation, the desertified land in Xinjiang is divided into 5 degrees as follows: the most severe desertified, severe desertified, middle desertified, light desertified and latent desertified lands. As Xinjiang has had great achievement on desertification prevention, desertification has been controlled in some areas, and the comprehensive management models have been set. But it still spreads in some area. Desertification and its prevention will be the important subject in the future.
