阿拉善高原沙漠化土地防治区划与治理对策

中国深受沙漠化危害，沙漠化土地防治区划是沙漠化研究和防治的重要措施。阿拉善高原地处亚洲干旱荒漠区，是中国北方沙漠化过程发生发展较为典型的区域。随着气候变化、区域社会经济发展和国家生态文明建设多项工程的实施，阿拉善高原土地沙漠化也发生了显著的变化。根据阿拉善高原沙漠化、土地利用变化、产业发展的过程和现状，我们认为区域沙漠化土地治理重点主要包括6个方面：重点生态功能保护区、三大沙漠交汇扩展治理区、荒漠植被保护与恢复区、人工绿洲生态建设稳定区、线性交通基础设施和片状工矿综合治理区及乌兰布和沙产业示范区。在此基础上，将阿拉善高原划分为3个荒漠化土地防治亚区和12个治理小区，并提出相应的沙漠化防治措施和治理对策。

Regionalization for Desertification Control and Countermeasures in the Alxa Plateau,China

China is one of the countries most seriously affected by desertification in the world. The Regionalization is an important content of desertification research and also the important work of desertification control. The Alxa Plateau is the typical region of desertification process in north China, which belongs to the Asia arid desert region. Desertification in Alxa Plateau is changed markedly along with the climate change, regional social-economy development and the implement of several National Ecological Civilization Construction projects. According to the process and current situation of desertification, land use and industrial development, the key points of the desertification control and rehabilitation countermeasures in Alxa Plateau are included six parts as below, the key ecological protection area, the three-desert meet and expand control area, the desert vegetation protection and rehabilitation area, oasis ecological construction sustainable area, linear transportation infrastructure and sheet mining rehabilitation area, and Wulanbuhe sand industry demonstration area. Therefore, the 3 desertification control sub-regions and 12 plots were regionalized in the Alxa Plateau, and the related rehabilitation countermeasures were presented.
