Study On Gansu's Food Security

China is a developing country with overmuch population and overless land. Ensuring food security plays an important role in all level government. Qua part and parcel of nation's food security, regional food security should receive much recognition. An adequate balance was realized in Gansu recent years. However, in the collar of poor natural environment, lack of resources, underdeveloped economy and incomplete institution etc, the position of Gansu's food security is still grim and cannot allowed pleased.Under the new situation, I'm trying to make a systematic study of Gansu's food security in the new situation. Based on a full understanding of the connotation of the regional food security, my paper has sized up the trend of Gansu's supply and demand, analyzed its practical status ground on data, construed the adverse conditions, drew lessons from abroad, and finally found some countermeasures to preserve Gansu's food security.Through the positive research of Gansu's food security, the result shows that:1.
