In recent years,many scholars predicte the food production with different theories and methods to ensure the security of national food production.In this paper,the methods of properties is used.Firstly,we deal with the statistical data to make them nondimensionalize.Secondly,we create qualitative mapping model.Lastly,we predict food production of ten years by longitudinal comparison of the various factors affecting food production with conversion degree function.The result shows that the method is practicable.
