Extended Abstract
Introduction and Objective: 264 million hectares, over 7% of the world's total forests, account for planted forest. Annually, roughly 5 million hectares are added up to this existing forests. In Iran, according to statistics there are 941000 ha planted forests. Planted forests are created with diver's goals. With respect to the role of industrial regions to cause air pollutants and also the role of trees and shrubs to absorb of these pollutants, one of the main goals to create this planted forest is to absorb these pollutants and help to improve of air quality. In the surrounding of industrial regions, it is ought to be covered with planted forest according to some environmental protective rules and regulations. Apart from the purpose of forest establishment, the major concern is the success at which planted forest species will be adapted and be successfully grown. It seems that what should be prioritized and be taken into consideration is the selection of appropriate species for those regions. For each selection including species selection for plantation it is necessary to have some criteria and indicators on which selection can be based. This research is exploring how to extract appropriate criteria and indicators for appropriate species selection in plantation of arid and semi-arid industrial regions.
Material and Methods: After literature reviewing and by specialist panel, 4 group criteria, 10 criteria, 16 sub criteria and 74 indices for evaluation and determination of degree of importance and importance percentage are offered to executive experts and academic specialists. Among these criteria and indicators based on Delphi questionnaire.
Results: 4 group criteria, 9 criteria, 13 sub criteria and 61 indicators are extracted and prioritized. From the view point of experts, ecologic group criterion, biological criterion, sub criterion of adaptability, ecologic indicator of drought resistance and management indicator of reduction in water consumption are of the highest importance for deciding on the species selection in arid and semi-arid industrial regions.
Conclusion: Based on the results of this research, indicators such as drought resistance, irrigation and maintenance cost, dust absorption ability, and irrigation efficiency are among the indicators that have a high percentage and degree of importance in the decision for species selection.
