Abstract:

Accurately delineating the background of China's land space pattern change since the 21st century and planning the future control of national land space scientifically and effectively is an important measure to realize the centralized management of landscape natural resources and China's beautiful vision. This study systematically identified the scientific connotation of the spatial pattern optimization and regulation. Then, the spatiotemporal characteristics of the national land space change since the 21st century were analyzed. Finally, we proposed the optimal allocation of the 2035 and 2050 beautiful vision and regulating modes of the realization of this vision. China has experienced rapid urban and industrial land expansion, arable land reduction, "grain for green" and other modes of land development and ecological protection in the 21st century. In the new era, it is necessary to strengthen the land space management and control of different development intensity types (artificial constructing activities, agricultural developing activities and natural ecosystem protection). It is also essential to strengthen the optimization of the internal structure of each ecosystem type and the improvement of quality to achieve the national food security, ecological security and sustainable development goals. At the same time, on the basis of the state detection, problem diagnosis and controlling threshold definition of the national land space background, the beautiful vision of 2035 and 2050 will be achieved. On the background of unified management of natural resources and the integration of multiple plans, the basic farmland protection and quality improvement, ecological grass and animal husbandry construction development, and the "target-oriented high-ranking examples" livable urban environment should be attached to the realization of the future vision of the national natural ecosystem protection.
