Abstract :
Destruction of area and changes in local ecosystem are viewed as the most important environmental impacts of mining operations in a region. Extents of disturbance area particularly waste dumps are also being increased as mining continues. Hence, environmental management and reclamation of mined lands play a major role in environmental protection in a specified mining region. With this respect, this paper describes optimum plant selection for reclamation process of mining in Chadormaloo mining complex as a case study. In all type of post mining land use such as Agriculture, Pasture, Forestry, Tourist attraction, Wild life creation, selection and planting the appropriate plant species is one the most essential requirements to successful implement the mine reclamation plan. The Research methodology is, Selecting of plant species that is on the basis of the primary factors that are: type of post mining land use, Climate, Nature­ of soil. Then priority is defined between the selected species, based on of the secondary factors by two Multiple Criteria Decision Making (MCDM) models that criteria 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. These models are implemented by FUZZY AHP and FUZZY TOPSIS methods. The mentioned procedure was applied to Chadormaloo iron mine in Iran. Decision making was executed on the basis of oral judgments and experts’ opinions in the case study. Results showed that among candidate plants, Artemisia sieberi, Salsola yazdiana, Halophytes types, and Zygophyllum, respectively, are ranked and prioritized as optimum plants for reclamation process using two methods.
