Abstract: The 20th National Congress of the Communist Party of China advocated for an ‘all-encompassing approach to food' and the establishment of a diversified food supply system. This paper analyzes the concept of an ‘all-encompassing approach to food' and identifies key elements of agricultural spatial planning within the broader framework of territorial spatial planning. A three-tiered planning strategy is proposed: 1) From the ‘large resource' perspective, coordinating the utilization of agricultural space to enhance the protection of farmland in terms of quantity, quality, and ecology, and balancing the allocation between farmland, grassland, and woodland. 2) From the ‘large industry' perspective, constructing an integrated agricultural industry system that encompasses the development of primary, secondary, and tertiary sectors. Emphasizing regional characteristics in establishing agricultural zoning and introducing regulatory guidelines with multiple orientations. 3) From the ‘large market' perspective, coordinating the entire industrial chain, optimizing the layout of modern agricultural industrial parks, and reinforcing spatial safeguards for the processing and distribution of agricultural products.
