摘　　要：随着经济的快速发展,我国居民的食物消费模式由以植物源食物为主向动物源食物为主转变。而且人口的增长和城市化、工业化进程的不断加快,耕地越来越少,对中国的食物安全造成了潜在的严重风险。本研究采用Gerbens-Leenes等和Kastner等的计算方法,分析了庆阳市食物消费模式与土地需求之间的关系。结果表明,庆阳市的食物消费模式比较单一,以植物源食物为主,肉类消费水平(2.08%)远远低于国家平均水平(9.03%)。随着未来生活水平的提高,食物消费结构将发生变化,动物源食品的消费量将增加,将需要更多的草地资源满足需求。因此,应加强草地的保护和建设,大面积恢复草地植被,大幅度提高草地生产力,提高牧草的产量和质量。这将有利于合理调整食物消费结构,更全面准确地评价食物消费结构变化对土地资源的需求,对维护国家生态安全和食物安全具有重要意义。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, industrializa- tion, have led to less and less arable land which creating potentially serious risks for China＇s 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.
