    RISK MANAGEMENT BASED LANDSLIDE INVESTIGATION AND MAPPING IN LOESS AREA

    • Landslide risk management has become one of the most important methods for landslide mitigation in the world. However, it starts relatively late and it is still in the initial stage in China (Hong Kong is an exceptional). The concept and techniques of landslide risk management widely used internationally have not been well implemented in the project of landslide investigation in China. This paper takes the project of landslide investigation at Baota district in Yanan city deployed by the land resources survey as an example. It analyzes the problem when doing the project about geohazards investigation, and the differences among the and the idea of risk management according to the guidelines for landslide susceptibility hazard and risk zoning for land use planning issued by JTC-11 and some new references. The landslide investigation implemented in China is medium scale and the investigation accuracy includes high, medium and low. A technical route and working thought about loess landslide investigation and mapping based on GIS, DEM, RS and ground survey is proposed. The study covers the four aspects including the landslide investigation and risk mapping at the scale of 1∶50000 and 1∶10000, the landslide investigation and risk mapping in villages, the important infrastructures and the representative landslides.The paper summarizes the loess landslide investigation and risk mapping methods at Baota district in Yanan city.
