摘要:
崩岗侵蚀威胁区域生态安全,是当前土壤侵蚀研究领域所关注的热点和难点。文章首先简要回顾了崩岗侵蚀的研究历程,介绍了崩岗的组成要素。随后重点从崩岗侵蚀类型、崩岗空间分布特征、崩岗发育阶段及形态特征、崩岗侵蚀驱动因素、崩岗侵蚀防治措施等方面总结了崩岗侵蚀及防治的研究现状与进展,探讨了当前崩岗研究的薄弱之处。并在此基础上,提出了崩岗水力重力侵蚀的耦合机理、崩岗发育与区域地貌发育的关系、崩岗产生及发育指标的建立、崩岗防治机理及其评价标准的建立等有待深入研究的问题。

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.
