Description :
Based on multi-temporal remotely sensed materials of both 1985 and 2000, the AA. analyzed the effects of land-use types and their conversions on desertification in Mu Us Sandy Land in the agro-pastoral transitional zone of north central China. In this study, the desertified land was classified into 5 degrees : potential, light, medium, severe and extreme. The results indicate that the extent of desertification expands slightly, while desertification degree is enhanced significantly. This research reveals that both improper land-use types and conversions could accelerate the desertification process.
