鄱阳湖水陆交错带乡村"三生"韧性空间格局及其耦合协调特征OA

[Objective]This study aims to comprehensively grasp the resilience characteristics of rural systems,provide a novel analytical framework for enhancing the sustainable development capacity of county-level rural areas,fill the gaps in existing research regarding micro-scale analysis and system coupling perspective,and offer practical insights for the balanced development of rural resilience in Yugan County as well as the sustainable development of rural areas in large lake basins.[Methods]This study focused on 382 administrative villages in Yugan County,Jiangxi Province,located within the aquatic-terrestrial ecotone of Poyang Lake.Based on the"production-living-ecological"(PLE)space theory,the subjective-objective weighting method and coupling coordination degree model were employed to analyze the spatial distribution of rural PLE resilience and its coupling coordination characteristics in 2022.[Results](1)In Yugan County,64.14%of villages exhibited medium or lower resilience levels,indicating an overall low resilience.The mean resilience values followed the order:ecological resilience>production resilience>living resilience.(2)The spatial differentiation of rural resilience was pronounced,with Yuting Town as the core high-value area,the northwestern lakeside plain ranking second,and the southeastern hilly region displaying the lowest resilience.(3)The PLE subsystems demonstrated high coupling degrees,all within the coordinated coupling stage.The coordination degrees exhibited a"central-optimal,northern-superior-to-southern"spatial pattern,with pairwise coupling coordination degrees mostly indicating mild or marginal imbalance.(4)The production resilience subsystem emerged as the primary constraint on improvement,with village road network density identified as the key obstacle factor.[Conclusion]The rural resilience in Yugan County is characterized by a relatively low level yet significant spatial disparities,along with a high coupling degree but a low coordination degree.Notably,the resilience level is significantly constrained by the production resilience subsystem.Therefore,to promote the balanced development of rural resilience,it is essential to formulate targeted strategies based on the current development status of towns and townships and the characteristics of their resource endowments.
