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

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.
