Due to the climate change and human activities,the impact of desertification in Qinghai becomes more serious in recent decades.Fast dynamic monitoring desertification by an effective technology is the necessary means to combating desertification.Based on the dimidiate pixel model,the vegetation coverage was estimated for Qinghai province using the MODIS data product-Enhanced Vegetation Index (EVI) from 2000 to 2012.The land desertification status and dynamic changes were rapidly monitored and assessed using vegetation coverage as the main index.The results show that remote sensing area of desertification in Qinghai is basically same as the conclusions of "A Bulletin of Status Quo of Desertification and Sandification in China".The spatial distribution characteristics of land desertification in Qinghai did not change obviously during the 13 years.However,the severe desertification area shows obviously downward trend.The sandification and desertification status in Qinghai are improved,and the ecological communities productivity and vegetation coverage of grassland in some regions gradually increase.This indicates that recent years forestry engineering and desertification control measures implemented in Qinghai gradually which exhibit ecological benefits and play a practical role.
