Abstract:: The spatiotemporal change of NDVI and its response to the variations of temperature and precipitation in the west of midstream of Hotan River in the Taklimakan Desert during the period from 1981 to 2014 were analyzed using the GIMMS NDVI and MODIS13Q1 time series data. The results reveal that: (1) half month’s NDVI decreased from 1 to 12, NDVI in spring and winter rose overall, but it presented the downward trend overall in summer and autumn, annual NDVI rose during the past 32 years; (2) from 1982 to 2014, the spatial distribution of annual NDVI moved to the south. greater NDVI mainly distributed in the southern slope and the western slope, for recent 33 years, increase regional area of NDVI was greater than the decrease in the study area; (3) vegetation coverage ranged from 0 to 0.004 3.
