Abstract: In the analysis food production process's incompatibility, to promote the food production in the main producing areas for the national food security is important. Using the food production statistical data, the food production's succession tendency and the spatial variation are analyzed. Grain yield's large scale growth mainly relies on the grain per unit area yield enhancement. The land delivers (grain per unit area yield) high and the low efficiency of resources coexist. Food production cost increase and food price rise cannot synchronous, appeared commissariat advocate produce a division of fiscal income and net income of farmers“ double low”phenomenon, become an obstacle to food security. Fluctuations in food production and food policy are closely related. To ensure national food security, Food policy can play an important role. The grain main production region in ensuring national food security has important role. Through the policy implementation of the fiscal, monetary and price to promote the development of major grain producing areas, explores a sustained, stable and harmonious development way that complies with the principle of synchronization to improve food production and farmers ' income, benefit coordinated between the main production areas and sales areas, not to sacrifice the interests for ecology and the environment in the grain main production area
