Land desertification has strong impact on eco-environment,ecological security and economic and social development.In addition,vegetation is regarded as one of the most important methods for land desertification control,so its growth analysis and changes detection become more and more important.In this article,MODIS,from 2005 to 2014,was used as the main data source to extract the NDVI(Normalized Differential Vegetation Index) for analyzing the trend of vegetation growth of desert areas in China over the past ten years.The results indicated that the vegetation growth showed a trend of continuous improvement in the desert regions of China in recent 10 years.The average NDVI in the period from 2010 to 2014 reached to 0.26,increasing 5.4% than that in the period from 2005 to 2009.The vegetation grew towards improvement in Hulun Buir,the middle and eastern part of Inner Mongolia and slightly increased in Alxa,Hexi Corridor and North Qinghai.The vegetation growth kept steady in Xinjiang region.
