Abstract:Typical coal mine closure areas generally face the dual dilemma of ecological degradation and socioeconomic decline. Scientifically measuring the resilience of the social ecosystem and formulating targeted restoration strategies are of great significance for the transformation and sustainable development of resourcebased cities. In this paper, taking Xuzhou city as an example, the theory of social ecosystem resilience has been and innovatively introduced into the study of coal mine closure areas. An evaluation index system covering ecology, society, economy and governance has been constructed. Combining entropy method and multi criteria decision analysis (MCDA) together, the resilience of various mining towns have been quantitatively measured and spatially differentiated in order to reveal key driving factors and gradient distribution patterns. It is showed that the resilience index of coal mine closure areas in Xuzhou city ranges from 0.38 to 0.66 with a spatial gradient pattern of "high medium low". The resilience of urban areas and towns with faster industrial transformation is the highest (0.66), while the resilience of areas with severe peripheral subsidence and single industries is the lowest (0.38). The results of entropy method for property rights confirmation show that the degree of collapse damage (0.28), natural conditions (0.22), and social capital (0.11) are main driving factors. It is indicated that ecological constraints and social adaptation jointly dominate system restoration. Based on the grading results, a differentiated restoration strategy is proposed: high resilience areas mainly rely on natural restoration and lowlevel intervention, medium resilience areas adopt a parallel path of manual restoration and industrial transformation, and low resilience areas rely on key engineering restoration and offsite compensation. The research deepens the application of the theory of social ecosystem resilience in closed mining areas. It will provide scientific support and practical basis for ecological restoration and sustainable transformation of resourcebased cities.
