ABSTRACT

In this study, the location of suitable areas for urban forest construction has been investigated. Geographic Information System (GIS) and multi-criteria decision analysis (MCDA) were used for this purpose. Based on the opinions of experts and past research, three main criteria were selected: ecological, access to urban services and socio– political terms. Also, sub-criteria were selected for each criterion and the desired spatial layers were prepared. Network analysis (ANP) method was used to categorize each criterion. For this purpose, the relevant questionnaire was prepared and after consulting experts, the weight of each criterion was calculated. The raster layers corresponding to each layer were prepared by fuzzy normalization method and the weight of each layer was applied in the corresponding layer. Then the layers were overlapped using the weighted linear combination (WLC) method and suitable areas for urban forest construction were selected. After locating, 8 areas were selected as proposed areas. Then 7 templates were selected and prioritized to categorize them. Then, based on the TOPSIS model, 8 options were prioritized and its map was presented.
