随着中国人民生活水平的提高，居民食物消费的优化升级将对农业资源需求产生重要影响。在这里，我们分析了中国粮食消费和农业资源需求的变化的基础上，谷物当量。我们发现，在总体发展趋势中，中国人的饮食消费仍以素食为主，但正朝着营养均衡、多样化的方向发展。食品消费结构优化调整加大了对农业资源需求的压力，农村居民食品消费是城镇居民的78.90%，说明城镇居民食品消费质量好于农村居民，城乡居民之间的这种差异正在加大。中国居民食物消费的区域空间分布呈现出结构一致性、南北差异性和民族差异性。从居民食物消费结构看，尽管我国直接食用食物的农业资源需求持续下降，但畜产品的农业资源需求压力却在加大。未来20年，随着中国粮食消费优化升级的持续，农业资源需求将增长25%左右，消费将取代人口增长成为影响粮食供给安全的首要驱动力。
With improving Chinese living standards, the optimization and upgrade of resident food consumption will have an important impact on the demand for agricultural resources. Here, we analyze changes in Chinese food consumption and agricultural resource requirements based on a cereal equivalent. We found that in the overall development trend, Chinese food consumption is still vegetarian but is heading towards balanced nutrition and diversity. Food consumption structural optimization and adjustment increases pressure on the demand of agricultural resources.Rural residents' food consumption is 78.90% that of urban residents, indicating that the quality of urban resident food consumption is better than that of rural people; this difference between urban and rural people is increasing. The regional spatial distribution of Chinese resident food consumption shows composition consistency and north-south and ethnic differences. Regarding resident food consumption structure, though the agricultural resource demands for directly edible food are continuing to decrease in China, pressure on agricultural resources for livestock product demand is increasing. The demand for agricultural resources will rise about 25% as the optimization and upgrading of Chinese food consumption continues over the next 20 years.Consumption will become the primary driver affecting food supply security and replace population growth.
