摘要：

To comprehend the variation of vegetation in Mu Us sandy land, the research use Mu Us sandy land as research area and make Uxin Qi(county) as a sample to anticipate the vegetation index variation on different land-use type. 365 images of Mod13 product are basic data which from 2000 to 2015 and the spatial resolution is 250m. The data will be input in ArcGIS10.3 to analyzed and draw graphs of average NDVI in July and August of Mu Us sandy land and Uxin Qi. Moreover, the research will draw a holistic graph of variation in Mu Us sandy land during the duration of 2000 to 2015. Besides, some of the meteorological elements has been analyzed to explain change of NDVI. The conclusion is the average NDVI although dropt in 2014 and 205 but grew gradually from 2000 to 2013, vegetation growth become optimistic and the main reason of the NDVI change are rainfall, air temperature and sunlight. But there are still some area of Mu Us heavily desert zing and it is harm for vegetation growth.
