中文摘要：

根据浑善达克沙区沙漠化发展过程、特征及其不同区域的自然和社会经济背景,将研究区划分为浑善达克沙地北部轻中度沙漠化土地强烈发展区、浑善达克沙地重度沙漠化土地不断发展区、浑善达克沙地南部轻度沙漠化发展区3区和5个亚区。根据亚区特点因地制宜积极进行沙漠化土地恢复治理的同时,充分利用区域资源优势、区位优势,调整优化产业结构,走农牧业生产集约化经营的道路,是浑善达克沙区达到沙漠化恢复治理和社会经济可持续发展的理想选择。

英文摘要：

According to severity, sub-regional characteristics of aeolian desertification and natural and socio-economic environment, the Otindag Sandy Land region is divided into three sub-regions： slightly-moderately aeolian desertification developing sub-region to the north of the Otindag Sandy Land, seriously aeolian desertification developing sub-region in the Otindag Sandy Land and slightly aeolian desertification developing sub-region to the south of the Otindag Sandy Land. Five lower sub-regions have been divided for the reason. In order to realize the sustainable development in the Otindag Sandy Land region, aeolian desertification should be actively controlled according to regional aeolian desertification characteristics. Meanwhile the industrial structure should be adjusted and the intensive agricultural and livestock production should be implemented.
