[Objective] Under the background of territorial spatial planning, optimizing land use patterns to enhance ecological resilience holds significant importance for promoting high-quality development in Jiangxi Province. [Methods] Based on the resistance-adaptability-resilience framework, the GMOP-PLUS model was employed to analyze and project the spatiotemporal variations of ecological resilience in Jiangxi Province from 2000 to 2035, and the geodetector was used to explore the driving factors of ecological resilience. [Results](1) From 2000 to 2020, construction land in Jiangxi Province increased the most, expanding by 2 578.50 km2, while forest, grassland, and cultivated land showed declining trends. By 2035, land use changes basically continued the trend from 2000 to 2020, with a decrease in cultivated land and an increase in water bodies and construction land. Variations in grassland and forest differed. Under the economic development scenario, grassland area increased most significantly(2 127.96 km2), while under the ecological protection scenario, forest area expanded the most (6 137.82 km2).(2) From 2000 to 2020, ecological resilience in Jiangxi Province generally declined, with the average value decreasing from 0.432 4 to 0.427 9, showing a spatial pattern of “high around the periphery and low in the center” and clustering characteristics. Compared to other scenarios, ecological resilience under the ecological protection scenario in 2035 improved most significantly, increasing by 6.59% compared to 2020.(3) From 2000 to 2020, the spatial differentiation of ecological resilience was mainly influenced by elevation(X1), human impact index(X7), and slope(X2), with average q values of 0.396 0, 0.283 6, and 0.117 8, respectively. Interaction results showed that the interaction between X1 and X7 had the most significant effect, with a q value of 0.708 0. [Conclusion] Ecological resilience varies greatly within Jiangxi Province and has generally declined in recent years. Future land management can adopt a coordinated economic and ecological development model to achieve sustainable development goals.
