Evolution and implementation pathways from desertification prevention and control to sandy land manage-ment and use in China
The construction of ecological civilization emphasizes holistic protection of"mountain-water-forest-farm-land-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 pre-vention and control,in that the links have not been effectively connected and the long-term and efficient desertifica-tion 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 per-spective 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 ba-sis,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.
