施行草地农业在食物安全上的“涟漪效应”

The ripple effect of implementing agro-grassland system on food security

我国长期以来高度关注粮食安全,导致过分倚重耕地农业,不仅加重了耕地的负担,而且过度扩大耕地面积导致生态遭到破坏,对农业整体资源缺乏统筹利用。近年来,随着我国经济的迅速发展,城乡居民生活质量不断提高,这就意味着我国人民的膳食营养结构和消费方向发生变化。针对我国人民饮食结构升级的现实,提出施行草地农业,将牧草作为植物生产的重要组分纳入农业土地利用,并突出草食家畜生产,实现农区与牧区的系统耦合,将在食物安全上引起一系列"革命性"变革。

Our country has paid great attention to grain security for a long time.The high attention of the agricultural land could aggravate the burden of cultivated land,the continuous expansion of cultivated lands could result in ecological destruction and the lack of systemic utilization in overall agricultural resource.In recent years,there were rapid development in economics and a continuously improvement of the living quality of urban and rural residents in China,which presumed some changes in their nutritional structure and consumption preference for diet.According to the fact on the structural upgrade of diet in China,it was proposed,in this study,that the agro-grassland system should be implemented and the pasturing grass should be considered and applied as a significant component in the cultivation and production of plant and the importance of herbivorous livestock should be emphasized,which lead to the implementation of system coupling of cropping and pastoral area,and would trigger a series of ＇revolutionary＇ changes in food security.
