The Benggang erosion and gully erosion threaten the regional ecological security, which are the hot and difficult points in the field of soil erosion research, however, it is not clear whether the control methods of gully erosion can be applied to Benggang erosion area. In this paper, the environmental factors affecting gully erosion and Benggang erosion were compared from the aspects of climate, parent material, soil, topography and vegetation. Combined with the appearance forms of Benggang erosion and gully erosion, the development process and the dynamic mechanism of erosion were expounded. Through comprehensive analysis, the erosive substance and erosive form of Benggang erosion are unique, and the interplay of more factors should be considered in the layout of control measures. On this basis, the development mechanism of Benggang erosion, the prevention and control measures and the establishment of erosion model are put forward.
