Designing of forest road network is a complex engineering problem. Therfore, the economic and environmentalissuuse should be considered in forest road network designing. The aim of paper is to develop a method using GIS andAnalytic Hierarchy Process (AHP) to design a forest road network with the lowest construction cost while maintainingother technical requirements. First of all, the required data was collected from the study area. Then the necessary mapsincluding slope, aspect, altitude, soil, geology and standing volume was determined as well as the importance coefficient ofeach layer of maps was determined via Expert Choice (EC) software. Then, road planning potential map was prepared byoverlaying these layers. Finally, the proposed road network techniqually evaluated by merging the planned road networkand road planning potential map based on Backmund criteria. Results indicated that the proposed road network withdensity of 10.67 m/ha and 81.6% road coverage is preffered to the existing road.
