Degradation of lands resulting from mining has side effects on environment of region, and reclamation operations is considered as an integral part of extraction operations. The most important methods of mined land reuse include agriculture, pasture, forestry, promenade, sports fields, filling, lake and construction. Selection of plant species and its planting in order to preserve the environment and reclamation the mine are one of the most important solutions. In a case study conducted out in the Sungun Copper Mine, species appropriate to initial factors of the reclamation plan were selected including type of land reuse extracted, the climatic conditions, and the nature of the soil. Then, the secondary factors (criteria) were determined, and the decision matrices were obtained based on the questionnaires completed by the experts, and the plant species, which were based on the landscape criteria of the region were prioritized using multi-criteria decision-making method including resistance against disease and insects, growth power and pattern, access to plant species, economic efficiency, soil protection, water storage, and prevention of different types of contamination. It’s noteworthy that weights of criteria were compared using fuzzy hierarchical analysis method and general prioritizing of the options, PROMETHEE methods and similarity to the ideal fuzzy option. The most appropriate plant species in the mining area by using the PROMETHEE method were obtained (Acer monspesulanum) (4.34), Fraxinus excelsior (2.85), Berberis vulgaris (-1.21), Paliurus spina -Christi (-1.33), Quercus macranthera (-1.47) and Prunus divaricate ledeb (-3.18), respectively. After planting these species, accepted results were obtained at the implementation site.
