Abstract
Intensive industrial activities have significantly degraded the ecological environment, restricting the transformation and development of Resource-Based Cities (RBCs). Enhancing urban resilience offers a significant pathway to sustainable development. Unlike traditional studies emphasizing macro dimensions, this study examines urban resilience from a spatial perspective, defining urban spatial resilience (SR) as the capacity to resist, absorb, and transform risks through the physical spatial layout of urban elements. A five-dimensional SR evaluation system including context, morphology, layout, function, and network was constructed. By analyzing multi-scale spatiotemporal SR variations across 108 RBCs under mining pressure (MP), priority intervention areas were identified. The results showed that: 1) From 2012 to 2022, the average MP of RBCs decreased from 0.3011 to 0.2887 and regenerative RBCs have the highest MP; regional disparities among grid units diminished. 2) The average SR of urban units increased from 0.3782 to 0.3878, and mature and regenerative RBCs have relatively high SR, with three-year averages of 0.39 and 0.3921, respectively. While the average SR of grid units decreased from 0.3432 to 0.3251, weakening polarization. 3) From 2012 to 2022, the spatial matching degree between SR and MP is in a reasonable state, but the Gini coefficient increased from 0.1082 to 0.1291, indicating that mismatched areas still existed. 4) Future interventions should mainly focus on high MP-low SR areas, particularly croplands, forests and grasslands. Urban context indicators are significant to improvement of SR, and future efforts should emphasize ecological restoration and refined land management.
