Abstract: [Objective] To clarify the changes in urban resilience and land use efficiency in Guangdong Province from 2013 to 2022, identify the spatiotemporal evolution patterns of their coupling coordination state and aggregation characteristics, with the aim of providing a scientific basis for promoting the coordinated development of resilient urban construction and intensive land use in the region.[Methods]The regional variations and evolutionary patterns in the coupling coordination between urban resilience and land use efficiency among 21 prefecture-level cities in Guangdong Province were analyzed using comprehensive evaluation methods, which encompassed the entropy weight method, the CRITIC method, the super-efficiency SBM model, the coupling coordination degree model, and the spatial autocorrelation model.[Results](1)During the study period, urban resilience in Guangdong Province continued to strengthen, with an increase of 43.21%. There are differences in the level of urban resilience construction among the cities, with a spatial distribution pattern of "gradually decreasing from the core to the periphery."(2) The fluctuation of land use efficiency has increased, rising from 0.57 to 0.65. However, land use has not reached DEA optimality, and most prefecture-level cities exhibit significant interannual volatility in land use efficiency, showing a spatial distribution pattern of "higher in the Pearl River Delta, lower in northern Guangdong, higher in western Guangdong, and lower in eastern Guangdong."(3) The overall coupling between urban resilience and land use efficiency is favorable and stable, exhibiting a sturdy and positive correlation. The coupling coordination level across the province has undergone an enhancement, transitioning from the initial coordination stage to the intermediate coordination stage. (4) Spatially, there exists a positive correlation in the coupling coordination between urban resilience and land use efficiency; however, localized agglomeration characteristics are not prominent.[Conclusion]Strengthen the linkage between resilient city construction and land spatial planning, optimize policy orientation, focus on unified coordination of regional planning, promote complementary advantages between cities, enhance agglomeration efficiency, and promote coordinated regional development.
