Abstract:

Food production and consumption constitute the core of agro-ecosystem, and decisively affect its structure and function and also the living environment of the mankind. The main agricultural activity is to establish and utilize a food system. A sound food system can improve agricultural productivity significantly, and balance the benefit between production and ecology, so as to maintain the sustainable development of ecosystem and to achieve food security. Increasing consumption of animal products and reducing consumption of plant products, especially grains, in people＇s daily diet will be the main direction for adjusting food system both in China and abroad. The ways for improving food system are considered herein. They include utilization of rangeland rationally, establishment of more sown pasture and implementation of cereal-pasture rotation systems, increase of herbivore livestock production,and use of arable land more efficiently.
