The requirements for land resources based on food consumption patterns:A case study in Qingyang

With the rapid development of economy, food consumption patterns is converting from plantbased foods to animalbased foods in China. Besides, population growth and urbanization, industrialization, have led to less and less arable land which creating potentially serious risks for Chinas food security. The present paper analyzes the relationship between food consumption patterns and land requirements of Qingyang using calculation method of GerbensLeenes et al. and Kastner et al. The results showed that food consumption patterns in Qingyang is relatively simple, concentrated mainly on plantbased foods. The consumption of meat is far below the national average. With the improvement of living standards in the future, food consumption patterns will change and food consumption of animal origin will increase, which will need more grassland to meet the requirement. Therefore, we should strengthen the protection and construction of grassland, restore a large area of grassland vegetation, improve grassland productivity greatly, improve the yield and quality of forage. This will help rationalize the food consumption patterns, access land requirement changes in food consumption patterns more comprehensively and accurately, The maintenance of the national ecological security and food safety is important.
