Abstract:

以2000-2010年近10a来鄂尔多斯地区沙漠化过程为研究对象,在利用MODIS数据对沙漠化动态进行监测的基础上,综合分析沙漠化逆转和发展地区气候变化和人类活动引起的NPP变化趋势,定量评估近10a来鄂尔多斯地区沙漠化动态及其与气候变化和人类活动间的关系.结果表明2000-2010年间,尽管鄂尔多斯地区沙漠化面积没有明显变化,但是沙漠化程度呈现整体逆转的态势,其中逆转的沙漠化土地面积达47057km2(占鄂尔多斯地区土地总面积的54.2%),比发展的沙漠化土地面积高出近3倍.气候变化是近10a来鄂尔多斯地区沙漠化逆转的主导因素,主要归因于2006年来降雨量的增加以及近10a来春季风速的减小,围封禁牧、退耕还林(草)等政策的实施及其与有利气候条件的耦合进一步加快了区域沙漠化的逆转.人类活动是导致近10a来鄂尔多斯地区沙漠化发展的主要因素,主要归因于部分地区生态保护政策的落实不力以及区域资源开发引起的环境破坏,完全由人类活动引起的沙漠化发展主要分布鄂尔多斯的北部地区.
