摘　　要：崩岗是红壤区最严重的一种土壤侵蚀方式,主要由集水坡面、崩壁、崩积体、沟底(包括通道)和冲积扇等基本单元组成。本研究把崩岗作为一个系统来研究,介绍了崩岗内部物质能量转化的规律和反馈机制,并对其治理做了有益的探讨。Dilapidated granite is the most serious soil erosion in red soil region.It mainly composes of the basic units of slope,collapsed wall,colluvial mass,gully bottom(including passage) and alluvial fan.The study takes dilapidated granite as a system,introduces the law of conversion of energy of internal substance of dilapidated granite and feedback mechanism and approaches its management.

关 键 词：崩岗系统 正反馈 负反馈 治理措施
