Abstract:The benggang is a typical type of severe erosional morphology with a very high intensity of sediment transfer. This erosional morphology is widely distributed in the granitic red clay soil regions in the seven provinces of southern China. Benggang erosion seriously threatens regional ecological security and has been a key and hot spot in the soil erosion community. This paper aims to review the existing benggang research progresses and provide some insight for strategies of the benggang restoration. The paper first reviewed the research process of Benggang erosion and made an introduction of the constituent elements of Benggang. Then, the research status and progresses of Benggang erosion and control technologies were summarized from five aspects: erosion types, zonal distribution characteristics, developmental stage and morphological characteristics, driving factors, and control techniques. The weakness of the current research was also discussed. Finally, the paper put forwards some scientific issues that should receive more attention, including the coupling mechanism of Benggang hydraulic erosion and gravity erosion, the relationship between Benggang development and regional geomorphic development, the establishment of index for Benggang formation and development, the mechanism of Benggang prevention and control.
