徐州市煤矿关闭区社会-生态系统恢复力评估与分区治理策略研究OA

Typical coal mine closure areas generally face the dual dilemma of ecological degradation and so-cio-economic decline.Scientifically measuring the resilience of the social-ecosystem and formulating tar-geted restoration strategies are of great significance for the transformation and sustainable development of resource-based 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 in-dex 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 adaptationjoint-ly dominate system restoration.Based on the grading results,a differentiated restoration strategy is pro-posed:high resilience areas mainly rely on natural restoration and low-level intervention,medium resili-ence areas adopt a parallel path of manual restoration and industrial transformation,and low resilience are-as rely on key engineering restoration and off-site compensation.The research deepens the application of the theory of social-ecosystem resilience in closed mining areas.It will provide scientific support and prac-tical basis for ecological restoration and sustainable transformation of resource-based cities.
