Abstract:Adjusting and optimizing the strategic paradigm of China’s agricultural regions in the new era is of great significance to the implementation of the “Greater Food” concept and the building of a strong agriculture. This study takes the layout adjustment of China’s agricultural regions during the Fifteenth Five-Year Plan period as its theme, and firstly summarizes the problems that exist in the main agricultural production regions and the layout changes in grain production bases. Then, in conjunction with the new requirements of the national strategies, the functional types of agricultural regions are refined, the different function positions are clarified, the adjusting idea of the agricultural region’s layout is established, and an optimized scheme is put forward for overall layout of agricultural regions, including eight main agricultural production regions, three sub-production regions, and six agricultural advantage production regions (i.e., “8+3+6”). Finally, this study provides specific suggestions for improving the functions of China’s agricultural regions and proper important construction projects.
