［Objective］ The resilience and management of cultivated land in the agro-pastoral ecotone of Inner Mongolia Autonomous Region were studied. To distinguish the resilience levels of cultivated land in this area， regional regulations and controls were effectively enforced， and targeted countermeasures were formulated to improve scientific reference for a sustainable utilization and protection of the cultivated land. ［Methods］ Based on resilience theory， 29 counties （banners） in the agro-pastoral ecotone of Inner Mongolia were selected as the study area. A pressure-state-response （PSR） model was constructed， with counties as the study units. The entropy method was used to comprehensively evaluate the resilience characteristics of cultivated land in the agro-pastoral ecotone . According to the combined characteristics of cultivated land resilience levels， resilience zones were delineated， and zonal management strategies were proposed. ［Results］ ① The meaning of cultivated land resilience was defined， and natural and social pressures， state， and response indicators of the cultivated land system were identified. A PSR model consisting of target， factor， and indicator layers was constructed. ② From 2000 to 2022， the overall resilience level of cultivated land in the agro-pastoral ecotone of Inner Mongolia was not high， showing a trend of higher resilience in the east and lower resilience in the west. Historically， influenced by the climate， the overall resilience level showed a declining trend， although resilience in the eastern region has recently recovered. ③ Based on a combination of changes in the cultivated land resilience levels， three zones were delineated. The first-level stable cultivation zone should strictly adhere to the red line of cultivated land protection and leverage the function of the grain production functional zones. The second-level monitoring and protection zone requires an increased artificial input to improve regional mechanization levels. The third-level fallow and restoration zone should adhere to a land use suitability pattern that promotes agriculture， pastoralism， and conservation， where appropriate. ［Conclusion］ The resilience of cultivated land in the agro-pastoral ecotone of Inner Mongolia Autonomous Region is generally low. It is necessary to strengthen the land consolidation and sandstorm control， achieve precision management， and improve cultivated land resilience.
