Abstract:
The MuUs Sandy Land locates in ecotone between cropping and nomadic area in China and its ecological environment has a strong sensitivity and vulnerability. Using MODIS images，meteorological and socio-economic data from 2001 to 2012，the paper studied the process of desertification and its driving forces in the MuUs Sandy Land and mainly drew the following conclusions：①In 2001-2012 in the MuUs Sandy Land，the very severe and severe desertification areas showed overall downward trends，while moderately and mild desertification areas showed overall upward trends. ②Average temperature in the MuUs Sandy Land increased at 0.044 9 °C/a and the temperature and precipitation were extremely beneficial to the reversed desertification.③Population，agricultural acreage，livestock numbers and the rapid economic development had more pressures on the MuUs Sandy Land，while the improvement of population quality，adjustment of production structure and the active policies played positive effects on desertification variations in the MuUs Sandy Land.
