Evolution and Phases Division of Collapsed Gully Erosion Landform
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 indicators which can reflect this regularity,we can make a further division in the developing phases of collapsed gully,which would have great significance in the treatment and control of collapsed gully.
