[Objective] Through exploring the framework of collapsed gully erosion risk assessment, to provide a scientific basis for prevention planning and staging control of collapse gully erosion in the South China. [Methods] The concept and methods of risk assessment, in combination with the research progress on the developing process of collapsed gully erosion were reviewed. Methods of risk assessment process was put forward with reference to the assessments of risk-liable ecological environment and geological disaster. [Results] Results in this paper included defining the connotation of risk of collapsed gully erosion, proposing the risk assessment method of collapsed gully erosion, establishing the risk assessment index system of collapsed gully erosion, and putting forward the risk assessment procedures of collapsed gully erosion. [Conclusion] Risk assessment provided a new idea and method for the study on collapse gully erosion and soil erosion.
