Abstract: The redevelopment of mining wasteland, as one of the effective ways to exploit stocking land, is important to the improvement of mining environment and the economic transformation of mining area. Given the destroyed nature of mining wasteland, the choice of redevelopment mode is crucial to ecological changes in the mining area. To ensure the redevelopment of mining wasteland, and realize the vision of ecological restoration, optimized layout of land use, and harmonious coexistence between human and nature, we constructed a theoretical framework for the redevelopment of mining wasteland with an ecosystem service perspective. Under this framework, the redevelopment target, model, and strategy were addressed by the methods of literature analysis, theoretical analysis, and case study. We concluded that: (1) The ultimate goal of mining wasteland’s redevelopment should be the improvement of socialecosystem resilience; (2) Five redevelopment modes, including supplyservice-oriented mode and support service-priority mode, are proposed following the theory of ecosystem services, with the multi-service synergy mode as the ideal one for redevelopment; (3) The direction of the redevelopment of mining wasteland depends on the trade-off and synergy among ecosystem services. In conclusion, from the perspective of ecosystem services, the redevelopment of mining wasteland should take a comprehensive measure for remediation and choose appropriate development mode suitable for specific site, with the goal of increasing total value of ecosystem services, improving social-ecosystem resilience, and promoting regional coordination and sustainable development.
