Research on the Optimization of Regional Layout of Grain Production in China from the Perspective of Effective Utilization of Water and Soil Resources
Over the years,China has achieved great success in grain production.However,with the evolution of the grain produc-tion pattern,the efficiency of water and soil resource allocation in China is low,posing a threat to long-term food security and ecologi-cal security.From the perspective of resource conditions in our country,grain production is facing a shortage of arable land and low quality.Water and soil resources are constantly being squeezed out in the trend of"non agriculturalization"and"non-grain growing".The uneven distribution of water and soil resources is subject to rigid constraints of spatial and temporal mismatch.The evolution of grain production layout further intensifies the contradiction between the supply and demand of water and soil resources in grain produc-tion.Therefore,leveraging the comparative advantages of resource utilization,rational layout of grain production,and improving the ef-fective utilization level of water and soil resources are the key to ensuring the sustainable development of grain production.
