Abstract: The whole world is facing unprecedented food security challenges under COVID\|19 pandemic. In order to understand the global food situation, this paper analyzed the worlds and Chinas food supply situation and food security response strategies, and put forward strategy to guarantee China food security. It was found that global grain production was  generally stable as expected, and high impact resistant. Chinas main grain supply was guaranteed, but imported commodities were affected at certain extent such as soybeans. Due to the various situations in different countries, each country adopted measures to protect their domestic food supply, such as increasing financial and policy support, raising food stocks, building green channels, restricting food exports, reducing import tariffs, and implementing price controls. On this basis, this paper suggested to stabilize grain production by cracking supply bottlenecks, control grain prices by strengthening regulation, and stabilize social expectations by effectively guiding the market to ensure China food security and the stable operation of the food supply chain.

摘要： 在新型冠状病毒肺炎（简称“新冠肺炎”）疫情背景下，全球的粮食保障面临前所未有的挑战。为掌握全球粮食状况，保障我国粮食安全，分析了全球和中国的粮食供应情况，并提出了粮食保障应对策略。通过分析发现，疫情之下全球粮食生产预期总体平稳，具有较强地抗冲击能力，中国的主粮供给有保障，但大豆等进口商品受到一定的影响。由于各国形势差异，不同国家采取了多种措施保障本国粮食供应，例如增加财政和政策支持、加大粮食库存、建立绿色通道、限制粮食出口、减免进口关税、进行价格管制等。在此基础上，建议通过破解供应瓶颈来稳定粮食生产、通过加强调控力度来稳定粮食价格、通过有效引导市场来稳定社会预期，以保障我国的粮食安全和粮食供应链的稳定运行。
