Dynamic evolution and driving mechanisms of coupling coordination between urban-rural integration and cultivated land use spatial transformation
摘要
Understanding the dynamic interplay between urban-rural integration (URI) and cultivated land spatial transformation (CLUST) is critical for sustainable territorial development in rapidly urbanizing regions. This study presents a comprehensive analysis of their coupling coordination in China’s Yangtze River Delta from 2003 to 2022, using an integrated framework that combines coupling coordination modeling with spatial autocorrelation and geographically and temporally weighted regression (GTWR). Results show that the coupling coordination degree (CCD) remained at a moderate to high level (0.5–0.7), yet exhibited pronounced spatial disparities, particularly a persistent north–south divide (mean CCD: 0.61 vs. 0.54). Spatial clustering patterns were statistically significant (Global Moran’s I, p < 0.01), and GTWR results reveal strong spatiotemporal heterogeneity, with policy and social factors emerging as increasingly influential drivers in the later stages. This research introduces a novel modeling approach for decoding spatially adaptive URI-CLUST linkages, offering empirical insights into the mechanisms underlying land system transitions. Beyond its regional scope, the findings provide a transferable framework for land-use governance in global urban-rural transitional zones. We recommend adaptive land-use zoning, differentiated rural support mechanisms, and cross-jurisdictional collaboration to foster equitable and sustainable transformation.
