Under the background of the national "double carbon" strategy and the realization mechanism of ecological product value, in order to solve the dilemma of "two skins" of mine restoration and transformation of ecological product value in the Nanling Ethnic Corridor, 20 multi-mineral mine restoration cases in the region were taken as samples, and the grounded theory was used to carry out system coding analysis. Firstly, the four key problems of inefficient utilization of waste resources, prominent technical bottlenecks, weak funding sustainability and ineffective cross-departmental coordination were identified. Then, combined with the core attributes of regional multi-mineral composite, cross-domain governance and national dependence, the four-dimensional optimization path of waste recycling revitalization industry, breaking through technical bottlenecks, innovating financial mechanism and strengthening system governance was constructed. The results show that the path can be targeted to solve the unique restoration problems in the study area and make up for the theoretical defects in the realization of the mine restoration ecological product value in the Nanling Ethnic Corridor. It not only opens up the transformation channel from "lucid waters and lush mountains" to "gold and silver mountains" for cross-regional and multi-ethnic areas and provides a replicable "Nanling experience", but also provides a methodological reference for the study of the realization of ecological products value in similar regions.
