中文摘要：

中国传统的粮食安全理念将以谷物为主的粮食等同于食物,致使农业走上了单一结构的“粮-猪农业”歧途,这也是中国粮食观与国际粮食观的不同之处。从食物生产结构以及食物安全评价就可以反映出传统农业的弊端,一方面食物生产过分偏重于谷物和猪肉,另一方面食物安全评价仅仅局限于粮食的供给能力。分析国内外食物安全评价体系,国外注重于微观层次的、营养膳食结构的评价,而我国注重于宏观层次的、数量安全的评价。草地农业发展潜力巨大,能满足我国对于动物性食物的不断加大的消费需求,是持久高效保障食物安全的最佳路径选择。

英文摘要：

The traditional Chinese food security concept equates grain to food and our agricultural policy lays undue stress on the importance of grain,which accelerates the formation of the “grainpig agriculture”.The food production structure and safety evaluation methods can reflect the drawbacks of traditional agriculture：on the one hand we pay too much attention to grain and pork production while on the other hand,the evaluation of food security is confined to the food supply capacity.Foreign food security evaluation systems focus on microlevel and nutrition structure,but domestic evaluation systems prefer macrolevel and food supply capacity. Traditional agriculture with a single production structure no longer meets the people’s need for increased animal food.We do not have enough grain to feed large numbers of graineating livestock if we still continue to give priority to the development of confined animal husbandry.A good solution for this problem is to develop plant-eating livestock to relieve the pressure on grain-eating livestock.Grassland agricultural systems can ensure food security not only in quantity,but also to satisfy the demand of increasing animal food consumption. Thus,it is the best choice of development for efficiently protecting our country’s food security in the long term.
