摘要：
Desertification and restoration could be assessed by long time-series vegetation index at regional scale. In this study, a new approach for desertification assessment based on analysis of NPP and MNPP change derived from the time-series MERIS NDVI data was promoted. Desertification and restoration in Xilin Gol League, Inner Mongolia, China were assessed and monitored during 2003 to 2011 by using the new method. Results showed that the desertification is severe in study area, 17.2% of lands were suffered from desertification in Xilin Gol League during 2003 to 2011. The ecological engineering projects implemented in the study area have achieved significantly, especially in the Otindag Sandylands.
