ABSTRACT

As the basic guarantee for the stable development of the country's economy and society, the food system has always been the focus of studies. Based on the perspective of sustainability, this paper constructs a comprehensive evaluation model of the food system for sustainability. We select a large number of representative indicators to establish a comprehensive index evaluation system for the carrying capacity of the food system , with arable land support, ecological support and socio-economic support as the criterion level, and quantitatively analyze the comprehensive carrying capacity of the global food system. According to the characteristics of carrying capacity and the results obtained, we classify the carrying capacity of the food system and explain its meaning in reality. Through data analysis and processing, we find that the carrying capacity of food resources under the global system is showing a steady upward trend. Although resource shortage and environmental problems such as climate warming are becoming more and more serious, the reduction in ecological support caused by this is not enough to reduce the carrying capacity of food system. Thanks to the improvement of food planting technology and the rapid economic development, the support of arable land and social economy have greatly increased. Therefore, the carrying capacity of food resources has been showing a steady upward trend.
