毛乌素沙区沙漠化土地防治区划

毛乌素沙区在自然条件、沙漠化程度和变化趋势及产业经济发展特征等方面具有明显的空间异质性，合理地进行区域沙漠化土地防治区划是因地制宜开展土地沙漠化防治工作的重要基础。选取自然条件、沙漠化发展过程及人类活动等方面12个指标，将毛乌素沙区划分为黄土高原与鄂尔多斯高原过渡区、毛乌素沙地腹地典型草原区和西鄂尔多斯荒漠草原区3个区、7个亚区、12个小区。在区域可持续发展战略的实施过程中，要根据亚区和小区的特点有针对性地进行沙漠化土地的防治，充分利用区域资源优势，优化产业结构，确保经济效益、社会效益和生态效益的稳步提升。

Regionalization for Aeolian Desertification Control in the Mu Us Sandy Land Region,China

There is a spatial heterogeneity on natural environment,aeolian desertification intensity and socio-economy development in the Mu Us Sandy Land region.Regionalization for aeolian desertification control is of great significance for scientific prevention and control of desertification according to local conditions.Based on twelve indicators on natural environments,aeolian desertification developments and human activities,we divided the Mu Us Sandy Land region into 3 regions (the transition zone of the Loess Plateau and the Ordos Plateau,the typical steppe region in the center of Mu Us Sandy Land and the desert steppe region in the west of Ordos Plateau),7 sub-regions and 12 lower sub-regions.We should take advantage of the natural resources and optimize the industry structure in order to simultaneously promote the economic,social and ecological benefits.In the sustainable development,the aeolian desertification can be more efficiently controlled by considering the characteristics of each sub-region.
