Zoning Dehloran National Natural Monument Using Fuzzy-AHP Method

Zoning is a technique for minimizing damages of protected area, by which we can delay damage time and cater for opportunities to make necessary decisions. This research aimed at evaluating the effectiveness of the Fuzzy-AHP model for zoning national natural monuments in Dehloran in Ilam province. To do so, all factors including slope, aspect, topographic map, soil texture, vegetation type, sediment condition, erosion type, land use, geology map, and wildlife map which were taken into account. In this study, Fuzzy-AHP method and GIS have been used for ecological assessment. Analysis and evaluation of modeling has been done based on raster layers and with the amount of Gama by 0.9 for the final layer Zonation map showing 5 zones including core zone with the area of 192.3 hectares (13 %), buffer zone with the area of 829.8 hectares (56%), expanded recreation zone with the area of 371.8 hectares (25%), intensive recreation zone with the area of 3.9 hectares (0.3%) and multilateral uses zone with the area of 86 hectares (5.7%). Buffer zone has the highest area of the region and plays as a protection belt around core zone and will reduce all kinds of damages.
