How the food system produces and distributes is a major issue relating to the people's livelihood in the world, and it is also the basis of national stability and development. In view of the universal problems of food system in various regions of the world, this paper constructs a set of food system model which is close to the reality. In order to reduce the influence of human factors on the this paperight, the entropy this paperig ht method was used to determine the this paperight of the food development index evaluation index. This paper find that environmental factors, such as carbon dioxide emissions, have an impact on the sustainability of the food system. It is recommended that the food system of the country be examined as comprehensively as possible and that the factors which have the greatest impact on the food system be identified. By constructing fitting linear regression equation to fit the data, the model has the function of prediction at the same time. Finally, this paper point out the advantages and disadvantages of the model, and extend the model to the larger grain system, economy and finance, medicine production, urban facilities construction, industrial production and other fields.
