Description :
This research integrated selected land degradation indicators (vegetation cover, proportion of drifting sand area, desertification rate, and population pressure) with geo-information techniques (remote sensing, geographic information system and global positioning system) to assess the severity of land degradation risk. The northern part of Shaanxi province in China was taken as a case study. Satellite images of the study were acquired in October 1987 and in October 1999 (Landsat TM images). All 5 thematic layers were generated in GIS environment at a scale of 1:250 000. The software used for this study was Arc/Info and ERmapper imagine.
