Abstract

Based on the MSS(1975), ETM+(2000) and CBERS-02b(2007) images, the authors conducted monitoring of land

desertification in Sanjiangyuan region with the emphasis placed on the characteristics and driving force of land

desertification variation. Desertification land is mainly distributed in the flat plateau, close to the river and roads.

The area of desertification land increased obviously between 1975 and 2000, especially in the Yellow River headwaters area,

because of the warming and drying as well as the disturbance of human activities such as panning and overgrazing. In

addition to the increasing desertification area, the degrading level was aggravated and the changes in spatial distribution

were frequent. After 2000, the Sanjiangyuan Reserve Area was set up with the purpose of reducing the impact of human

activities as much as possible. On the other hand, the precipitation was increasing. Since then, land desertification in

Sanjiangyuan region has tended to be improved.
