Abstract:
The comprehensive study of natural resources plays an important role in mapping out the "base" of various resources in China, in which resources flow is an important field of resources science research in China, is an important aspect of the management of natural resources in a reasonable manner and promote the of economic, environmental and social coordination. Resource flow research plays a pivotal role in national resource and environmental management decisions. A systematic study of the vertical and horizontal flows of various types of food resources in China has revealed the evolution of the spatial and temporal pattern of food supply and demand and quantitatively measured the efficiency and resource and environmental impacts of each link of food from production to consumption, the results showed that the phenomenon of wasting food consumption link and its huge resources environmental impact should not be ignored. In the current new era, the complex environment at home and abroad, such as trade friction between China and the United States, the monopoly of international food traders, and the changing dietary concepts and dietary structure of domestic residents, have posed greater challenges to the smooth operation of food security in China, and it is crucial to establish a new era of national nutrition and food security.
