Abstract: As one of the important contents of mine environmental management, the evaluation of the effectiveness of mine ecological restoration is of great significance for testing the effects of ecological restoration. A scientific effectiveness evaluation method is helpful to ensuring the smooth progress of mine ecological restoration projects. Taking the abandoned open-pit mines in the Yangtze River Economic Belt as an example, a watershed scale evaluation method for mine ecological restoration was established by analyzing multi-source mine ecological environment monitoring data, which considered three first-level indicators of social, ecological and economic benefits, and 10 second-level factors such as the improvement of human settlement environment and utilization rate of transition. Remote sensing methods were used to analyze the changes in land use and vegetation coverage before and after the project implementation, and the social, ecological and economic benefits of mine ecological restoration were quantitatively analyzed. The results showed that the total score of the ecological restoration effectiveness of abandoned open-pit mines in the Yangtze River Economic Belt is 74.8, with the scores of social, ecological and economic benefits being 19.4, 39.6, and 15.8, respectively, indicating good benefits. With clarifying the restoration tasks and goals as a prerequisite, the provinces along the Yangtze River Economic Belt should further exploit the potential of land reclamation, actively implement the later management and protection measures, and enhance the various benefits of ecological restoration of abandoned mines. This study is of great significance for mine environmental management and can provide support and decision-making basis for ecological restoration supervision of abandoned mines.
