【摘要】：正改革开放以来,我国居民的膳食结构发生了巨大变化,如主粮消费显著减少,肉奶蛋消费迅速增加.30年来,我国居民年人均口粮消费减少了47%,而动物性食品消费增加了160%;伴随而来的是在粮食消费结构中,居民口粮占比逐年下降,而饲料用粮消耗逐年增多,2012年饲料粮占我国粮食总产量的40%[1,2].这意味着,我国"粮食安全"的本质已演化成饲料粮的不足.然而,我国农业结构和生产方式并未适应这一变化,政府依然强化口粮生产,而忽视动物饲料粮的供应问题.
[Abstract]:Since the reform and opening up, the dietary structure of Chinese residents has undergone great changes, such as the consumption of staple grain decreased significantly, the consumption of meat, milk and eggs increased rapidly. In the past 30 years, the annual per capita food consumption of Chinese residents has decreased by 47%. The consumption of animal food increased by 160. Accompanied by the food consumption structure, the proportion of food rations of residents decreased year by year, and the consumption of food for feed increased year by year. In 2012, feed grain accounted for 40% of the total grain output in China. [This means that the essence of "food security" in China has evolved into a shortage of fodder grain. However, the agricultural structure and mode of production of our country have not adapted to this change, and the government is still intensifying the production of rations. While ignoring the supply of animal feed food.
