世界粮农组织制定的粮食安全标准有三项,一是粮食自给率达到95％,二是人均占有量400公斤,三是当年储备占生产量的18％。按此标准,成都市的粮食生产能力早已处于安全线下。成都得益于都江堰,号称“天府之国”,好象不会出现粮食短缺。但从实际的情况看,形势正日益严峻。 There are three food safety standards formulated by the World Food Program. The first is food self-sufficiency rate of 95% and the second is 400 kilograms per capita. The third is that the reserve accounts for 18% of the production volume. According to this standard, Chengdu’s food production capacity has long been under the safety line. Chengdu benefits from Dujiangyan, known as “land of abundance”, it seems that there will be no food shortage. However, from the actual situation, the situation is increasingly grim.
