多元化食物供给体系的概念界定与构建对策OA北大核心CSTPCD

The concept of Diversified Food Supply System(DFSS)is complex and has not yet reached consensus,which can easily lead to the diverging food policy practices in China.With the aim of enhancing the level of food security governance under an all-encompassing approach to food,based on summarizing the policy origins of DFSS,the policy priorities of different food types and the four-pronged connotation of'diversification',this study defines DFSS as a complex system that expands food sources through the orderly utilization of arable land resources,the development and utilization of various types of land resources,the promotion of the common progress of various types of food production technology,and the expansion of food import sources,in order to meet the increasingly diversified demand for food consumption under a governance system that ensures the priority of food supply security.By analyzing the challenges of the constructing a diversified food supply system,specific construction countermeasures including synchronously improving the comprehensive food production capacity and clarity of arable land governance,reducing the marginal cost of forestry,animal husbandry and fishery production in non-cropland areas,exploring differentiated agricultural industry development modes,and adjusting the pattern of the international supply chain of soybeans and corn are proposed in this study.
