Abstract: This study focuses on the ecological restoration of abandoned mines to develop an evaluation model and propose policy recommendations. The research highlights that while mining contributes to economic growth, it also brings numerous abandoned mines and associated environmental issues. Western countries initiated research on abandoned mines earlier, while China continues to explore various restoration approaches. This paper, adhering to the principles of scientific validity, employs the analytic hierarchy process (AHP) and entropy method to construct an evaluation indicator system. Seven indicators were selected, and their weights were determined using both methods to derive the combined weights. The results indicate that factors such as the water source conditions significantly influence the selection of restoration methods, with different approaches yielding varied evaluation scores. Based on this foundation, sustainable development strategies are proposed for development models regarding composite tourism development, geopark development, and ecological regreening. These strategies include enhancing resource utilization efficiency, strengthening ecological protection, and promoting the transformation of ecological value, etc. The aim is to align the rehabilitation of abandoned mines with the goal of sustainable development, offering a scientific basis and policy guidance for the ecological rehabilitation of mines while fostering the sustainable development of the region.
