Relationship between normalized difference vegetation index(NDVI) and climate factors were analyzed in the south of Gurbantunggut Desert using the NASA/MODIS data(from 2000 to 2009) and meteorological data in Fukang City.The results showed that the annual average temperature,precipitation and NDVI has increased in the past 10 years.The monthly variation of NDVI showed a slight double-peak pattern,with the first maximum in May,the second maximum in August and the minimum in February.The rescaled range analysis of NDVI showed that yearly and seasonal temperature,precipitation NDVI will increase continuously in the future,and NDVI change will coincide with the change in temperature and precipitation.
