毛乌素沙地地处我国农牧交错带,生态环境具有较强的敏感性和脆弱性.采用MODIS图像、气象和社会经济等数据对2001年-2012年毛乌素沙地的荒漠化过程及驱动力进行了研究,主要得出以下结论:①2001年-2012年毛乌素沙地极严重荒漠化和重度荒漠化面积总体呈下降趋势,中度荒漠化和轻度荒漠化面积呈上升趋势.②毛乌素沙地年平均气温以0.044 9 °C/a的速率呈显著增加趋势,温度和降水的增加对自然荒漠化逆转极为有利.③人口、耕地面积、牲畜数量和经济的快速发展对毛乌素沙地施加了较大的压力,但人口素质的提高、生产结构的调整以及积极政策的实施对毛乌素沙地的逆向演替起到了积极的作用.

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.
