Abstarct: In this research, baxsed on geographical information system (GIS), considering the natural characteristics, field observations and using nine quantitative and qualitative variables, landslide hazard zonation in 1 to 50 kilometers of Khorramabad – Pole zal freeway, has been carried out. The study area is located on 20 kilometers south of Khorramabad in Lorestan province is a part of Tehran-Bandar Imam first class road. In order to provide landslide hazard zonation two methods (bivariate statistical method and systematical approach) have been used in this survey. In these methods, the required maps (slope, slope direction, fault, lithology, earthquake velocity, dip direction, elevation trenches, GSI) provided with Arc/GIS software and finally map of landslide hazard has been prepared. Finally, for evaluating the accuracy of data, the landslide distribution map has been compared and evaluated. The obtained results show that the systematical approach includes the little error. Also, in this research, the most important variables and effective parameters on landslide in the study are slope, tranche elevation, and GSI. Key words: landslide, zonation, Khorramabad-Pole zal Freeway, bivariate statistical, systematical approach.
