中国居民人均饲料用粮需要量分析——基于中国居民膳食营养素推荐摄入量视角

Study on Per Capita Grain Feed Grain Requirement Based on Chinese RNIs

满足人们基本营养需要的粮食包括口粮和饲料用粮。建立人均口粮和饲料用粮安全的数量标准,对准确判断我国粮食安全状况进而采取有效措施实现粮食安全具有重要意义。笔者在前期研究人均口粮需要量的基础上,以中国居民膳食营养素推荐摄入量为依据,利用中国食物成分表和不同年龄男女居民在总人口中的比重,计算出符合营养标准的年人均饲料用粮需要量为123公斤。这一数量可以作为目前我国食物消费结构下饲料用粮安全的数量标准。

The grain which can meet the basic human nutritional needs includes grain and feed grain.The establishment of the quantity standard for per-capita grain ration and feed grain security has important significance on the accurate judgment of food security situation and taking effective measures to achieve food security in China.On the basis of the prior study on the per-capita grain ration requirement,according to the Chinese recommended nutrient intake（RNIs）,the article uses the Chinese food composition tables and the proportion of different aged male and female residents in the total population to calculate that the annual per capita feed grain requirement which can meet the need of the nutritional standard is 123 kg.This number can be used as the the quantity standards of the feed grain under current food consumption structure in China.
