ABSTRACT

In recent years, landslide disasters have occurred frequently, and the risk analysis of landslide disasters is an important basis for disaster prevention and reduction; hence, it is of great significance to carry out regional landslide risk research. Taking Panzhou City, Guizhou Province as research area, with the support of multi-source data, using the random forest model of regional landslide hazard analysis, the results show that the high-risk area is located in the low elevation area, the areas of the landslide have frequent human activities, which is mainly distributed by soft rock and soft hard alternate with class two of petrofabric rock engineering. It covers an area of 214.2 km2, accounting for 5.3% of the total area of the study area. The prediction results are basically consistent with the actual situation.
