The construction of ecological civilization emphasizes holistic protection of "mountain-water-forest-farmland-lake-grassland-sand", which has become an important concept of desertification prevention projects in arid and semi-arid areas of China. In the past, sandy land management and use have been neglected in desertification prevention and control, in that the links have not been effectively connected and the long-term and efficient desertification prevention has not been realized. Therefore, combining Qian Xuesen's understanding of "deserticulture", we comprehensively discussed the "long-term achievements" of China's desertification control miracle from the perspective of the historical evolution of the interaction of technology and practice, and the strategic development of policy guidance. Further, we defined the concepts of desertification prevention, desertification control, and sandy land management and use. We analyzed the coupling and coordination relationship between the four links and the scientific principle based on the development of ecological industry chain. Finally, we put forward the policy and market realization pathways, with efficient sandy land management as the core, desertification prevention as the basis, desertification control as the channel, and long-term sandy land use as the foundation. We expected to provide theoretical and practical guidance for creating a new miracle of China's desertification prevention and control.
生态文明建设强调“山水林田湖草沙”一体化保护,也是中国干旱区实施防沙治沙工程的重要理念。但过去在防沙治沙的过程中忽略了管沙和用沙,即各环节之间尚未有效衔接,未能实现长效、高效的风沙防治。本文结合钱学森对“沙产业”的理解,从技术和实践的互动、政策指导战略化发展的历史演变视角,综合论述了“久久为功”的中国治沙奇迹,界定了防沙、治沙、管沙、用沙的概念,分析了4个环节之间的耦合协调关系和基于生态产业链发展的科学原理,提出了以高效管沙为核心、防沙为基础、治沙为渠道、长效用沙为根本的政策性和市场化实现路径,以期为创造中国防沙治沙新奇迹提供理论和实践指导。.
