  In order to evaluate the effects of forest road on vegetation and some soil properties was selected a road with the length of 400 m. Type and number of regeneration species of trees and shrubs in plot area of 100 m2 and type and cover percentage of herbaceous species using minimal area method were recorded in plot area of 64 m2 and herbaceous species was classified into two groups using Two-Way Indicator Species Analysis (TWINSPAN). Samples of soil were taken in depth of 0-10 cm. Multivariate analysis methods ( PCA and CCA ) and ANOVA were used to recognize the most important soil variables and determine relationship between species composition and soil factors. Results indicated that species composition of plots in near the road has been varied in comparing with plots of inside the forest and it was classified into two separate groups . Percentage of moisture content , saturation moisture , clay , porosity and organic carbon in plots near to road decreased , while the amount of sand , silt, bulk density and pH were increased in this site. Among the regenerations Alnus subcordata abundance had significant difference between the edge of the road and inside the forest. The findings showed that the roads affect to adjacent ecosystem effectively and it is essential to reduce the damage and disturbance in construction of forest roads.
