As the world's largest developing country,the ability of China's agricultural resource utilization to effectively support the current and future food security goals has been affected by a variety of factors(e.g.,transformed supply channels,tightening international situation and frequent emergencies)in recent years and has attracted extensive attention from the academic community subject to multiple factors.This study uses literature review,statistical analysis,and spatial analysis methods to systematically explore China's food security situa-tion in the context of farmland resource constraints.It is found that the demand-side pres-sures such as demographic changes,social class differentiation,and dietary structure ad-justments derived from economic growth and rapid urbanization have placed extremely high expectations on food supply.However,the quantitative restrictions,utilization ways,and health risks of farmland resources on the supply side constitute a huge hidden concern that affects the stability of food production.Although China's farmland protection system is un-dergoing a transition from focusing on quantity management to sustainable use,the matching and coordinating demand pressure and supply capacity for food security is unbalanced.Therefore,facing uncertain future development scenarios,policymakers should focus on building a resilient space for China's farmland protection to withstand the interference of major emergencies.The existing farmland protection space policy can be integrated by es-tablishing a national farmland strategic reserve system(based on resilient space),and further development of targeted use control measures for zoning,grading,and classification will help realize sustainable China's farmland resources use.
