Abstract：Slope collapse is a special type of soil erosion in southern China.It is widely distributed in the red soil region of southern China,and it is one of the important ecological problems in this area.It has been nearly 20 years since the first slope collapse investigation,and great changes have taken place in the relevant situation.The unclear status of slope collapse has directly affected the planning and decision-making of administrative departments on the prevention and control of slope collapse,and it is urgent to carry out a new round of slope collapse investigation.The high-quality development of soil and water conservation in the new era provides opportunities for the slope collapse investigation.The differentiated classification prevention and step-by-step implementation put forward higher requirements for the slope collapse investigation.Modem information technology provides a new method for the slope collapse investigation.Guided by the service slope collapse risk assessment and prevention planning,on the basis of making full use of the results of the first slope collapse investigation,the small mountain investigation of collapse development will be supplemented,and the typical investigation will be changed into a comprehensive investigation.The object and scope of the investigation,the content of the investigation,the procedures and methods of the investigation are systematically discussed,which can provide reference for the administrative departments and technical units to start a new round of slope collapse investigation.
