摘　　要：崩岗是我国南方水土流失的一种特殊类型,广泛分布于南方红壤区,是该区域严重的生态问题之一。第一次崩岗调查距今已近20年,相关情况已发生巨大变化。崩岗现状不清直接影响了行政管理部门对崩岗防治相关工作的规划和决策,因此急需开展新一轮崩岗调查。新时代水土保持高质量发展为崩岗调查提供了机遇,差别化分类防治和分步实施对崩岗调查提出了更高要求,现代信息技术为崩岗调查提供了新方法,以服务崩岗风险评估和防治规划为导向,在充分利用第一次崩岗调查成果基础上,补充崩岗发育的小山体调查,将典型调查改为全面普查,系统探讨崩岗调查对象与范围、调查内容、调查程序与方法,以期为行政管理部门和技术单位启动新一轮崩岗调查工作提供参考。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.Modern 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.
