雾灵山自然保护区研究——Ⅱ.“屋檐”式地貌的形成机制与调控

Study on Wuling Mountain Natural Protected Region: Ⅱ.Formation Mechanism and Control on Roof\|edged Relief

阐述“屋檐”式地貌的特点，认为该地貌的形成受多种因素影响，形成过程包括浸蚀、冲蚀和侵蚀三个阶段，该地貌对环境景观具有重大破坏作用。

Roof\|edged relief,which can be found on steep slope,is a special one in Wuling Mountain,it contains upper and lower soil horizon,the latter can easily be washed away by water.This relief is caused by six factors:relief,soil,climate,vegetation,hydrologic condition and human activity.Its formation process can be divided into three stages,they are etching,ablation and erision.This relief can prevent plant from growing properly,cause severe ecological problem and change the drainage system.To control the formation of this relief,it is necessary to limit human activity,reinforce the lower horizon and control the water flow on steep slop.
