| 摘 要： | 崩岗是中国南方一种常见的土壤侵蚀类型,也是一种严重的水土流失方式,多分布于低山丘陵区的花岗岩风化壳之上.崩岗的形成和发展是2个不同的阶段,并始终受到水力和重力的作用.2种外力对比关系的不同使崩岗的演变过程具有明显的阶段性.通过选取适当的指标体现这种规律性,可以对崩岗的发展阶段进一步划分,对崩岗的治理控制具有重要的意义.

| Abstract: | Collapsed gully,as a common type of soil erosion and a serious way of soil erosion in southern China,is mainly distributed in hilly areas on the top of granite weathering crust.The formation and development of collapsed gully,which have always been under the influences of water and gravity,can be divided into two different phases.It is the transformation and interaction between the two kinds of exogenic agents that make the evolution of collapsed gully display different phases.By selecting appropriate indic... |
