Abstract:: The county roads of low mountain and hilly regions in semiarid area of Inner Mongolia North, are seriously eroded, which impact the local transportation. The roads are often forced to change their courses and occupy cultivation due to erosion, which seriously affects the development of local countries. This article took agricultural area as an example in Siziwang County which lies the foot of the North Yinshan Mountain, through a great deal of investigation on the spot, erosion characteristic and the road erosion causes were studied from two aspects of natural and human, the occurrence mechanism of the roads erosion was analyzed. The results show that the main factors affecting the soil road erosion of the rural are the road surface slope and rainfall intensity, the using mode of human beings also directly affects the road erosion. The soil roads universally develop different levels of erosion, which lies on the slope and the catchment in the valley; the limited several events of strong precipitation which happens in summer are the important reason for the road erosion in the study area. The roads are seriously eroded which lie the high slope surface and the catchment in the valley. The roads surfaces on both sides of unequal height and loamy soil are all easily eroded. The seasonal human using and the lack of maintenance made the roads erosion serious.
