Abstract

Every year, thousands of kilometers of FOREST ROADs will be constructed by which millions of acres of vegetation and trees are destroyed and millions of cubic meters of soil moved. This research to investigate the effects of some topographic elements and ROAD AGE on area erosion of edges FOREST ROADs to 150 meters distance in education- research Forest of Tarbiat Modares University. Initially, maps of slope, aspect and elevation were obtained. Then, the erosion forms of the region around the road were surveying 'Using GPS. The results of the survey showed that the maximum side effect of road on the erosion is 48 meters away from the edge of the road. So the results of the one way analysis variance showed that, between erosion area phenomenon with different classes' slopes, elevation and age roads have existence significant on the level 5 percent level and with the aspect have existence significant on the 1 percent level. So that 15-30 percent slopes, north-west aspect, altitude of 600-800 meters and 3 years of age class have the most area of erosion. The results of regression model showed that the slope provided the most important factor affecting the increase levels of erosion and the then of slope area, age road is the most important factor influencing the extent of degradation of FOREST ROADs in the study area.
