林道建设是林业中成本最高的作业。在不适合的地区设计和建造道路可能会增加建造和维护成本，并造成许多环境影响。因此，要求对林道设计给予更多的重视。在本研究中，我们试图介绍一个合适的方法，同时使用地理信息系统和层次分析法定位林道。确定了林道选址中最重要的坡度、土壤类型、地质、水文网络、坡向、每公顷林木蓄积量m3、树种类型和高程图，运用专家思维和层次分析法，将研究区划分为林道建设很好、好、中、差和差5个等级。然后在准备好的AHP图上设计了两个新的变量：第一个变量是用传统方法设计的，第二个变量是用Pegger扩展设计的。基于AHP图，从路径优劣的角度来看，Pegger规划变体（PP_variant）的路径效率最高。研究结果表明，将层次分析法与地理信息系统相结合，可以为林道网规划提供一种合适的方法。
Forest road construction is the most costly operation in forestry. Road designing and construction in unsuitable areas may increase construction and maintenance costs and also cause many environmental impacts. Therefore, it is required to pay more attention to forest road design. In this research, we tried to introduce an appropriate method for locating forest roads using GIS and AHP simultaneously. The most important layers in locating forest road include slope, soils type, geology, hydrographic networks, aspects, trees volume m3 per hectare ,tree type and elevation maps which were determined and then by using expert thought and AHP method the study area was classified in five classes including very good, good, medium, bad and worse for forest road construction. Then two new variants were designed on the prepared AHP map: the first variant was designated using traditional method and Pegger extension was applied to design the second. Pegger Planning variant (PP_variant) had the highest efficiency in path from good and bad points of view based on AHP map. The results of this study illustrated that using AHP and GIS simultaneously can introduce an appropriate and suitable method in the forest road network planning.
