Abstract
 All steps of a mining project generally disturb the environment’s original condition during execution. Therefore from exploration until end of the exploitation and after mine closure, should be implemented an exhaustive mine reclamation plan of the mined land. Planting the suitable plant species in each step of any reclamation plan and each area is one of the necessities in this respect. plant types were selected based on reclamation plan primary criteria that are: Type of post mining land use, Climate, Nature­ of soil. Then, comparison matrixes based on questionnaires that were completed by experts were obtained and plant types were prioritized by Fuzzy AHP method based on secondary criteria that are: Perspective of the region, Resistance against disease and insects,­ Strength and method of growth, Availability of plant type, Economic efficiency, Protection of soil and storing water, Prevention from pollution.The mentioned procedure was applied regards Sungun open pit copper mine in Iran as a case study on Arasbaran region. Decision making was executed on the basis of oral judgments and group expertise in the case study. The outcome results have been consisted of Acer monspesulanum, Fraxinus excelsior, Quercus macranthera, Berberis vulgaris, Paliurus spina –Christi, Prunus divaricata ledeb, respectively by reason of maximum priorities that are recognized for mine reclamation.
