“…The ecological restoration benefit mainly refers to the improvement of the ecological environment quality of abandoned mines through the preparation of restoration, land reclamation, and other measures [16][17]. Currently, the existing methods for assessing the restoration benefit can only give the corresponding assessment results for the overall changes in the ecological environment of abandoned mines over a period of time and are unable to realize the dynamic monitoring of the change of the benefit [18][19][20]. In view of the current situation, it is necessary to carry out research on the construction of a dynamic assessment model of the ecological restoration benefit of abandoned mines.…”

The escalating spread of industrial wastelands has spotlighted the need for effective ecological restoration. This paper introduces an evaluation system for assessing the environmental restoration benefits of such wastelands, integrating the entropy weight and optimal assignment method for index quantification. Enhancements to decision-making elements and the incorporation of the fuzzy comprehensive evaluation method have culminated in developing a D-FCE model-based ecological restoration benefit assessment model. An empirical analysis on selected sites revealed notable increases in soil organic carbon content post-restoration—ranging from 1.73% to 2.98% in ERL areas, 1.69% to 2.45% in GL areas, and 1.25% to 2.08% in AL areas—demonstrating significant carbon sequestration. Additionally, a 38% rise in ecological benefits was observed, translating to an economic boon of 8563.2 yuan/year. This study furnishes a scientific method for evaluating industrial wasteland restoration and underpins the formulation of pertinent policies.
