摘要： Shifting to more sustainable use can curb cropland resource degradation and improve production resilience. However, most cropland use assessments are unilaterally focused on biophysical levels and productivity, ignoring the multi -dimensional aspects of degraded cropland. This study attempts to describe cropland use stability in China by proposing a multi -dimensional assessment framework (including quantity, quality, management, service, and risk) to provide a reference for designing land degradation -neutral strategies. Results show that multi -dimensional cropland use characteristics present significant spatial heterogeneity. Western regions are reserve resource agglomerations that can replenish cropland quantity. In contrast, main grain -producing areas cover most current resources with preferably cultivation quality, management efficiency, and ecosystem services, while risk resistance is weak (especially in Middle -lower Yangtze Plain). Generally, the stability of cropland use in Northeast Plain is the highest and in Loess Plateau the lowest. Besides, urbanization will occupy about 9.31% of the high -stability cropland in 2030, of which 70.29% will occur in Northeast Plain and Huang -Huai -Hai Plain. The total potential productivity loss in Huang -Huai -Hai Plain alone will reach 100.1 kt, equivalent to supplying the food demand of 199,200 people annually. Therefore, a sustainable -oriented refined cropland management strategy should be designed according to the hierarchical nested spatial layout of comprehensive planningstability map -multi -dimensional utilization characteristics to ensure the loss -replenishment balance and stable production.
