Zudong Longnan County area landslide hazard assessment by the information model and ArcGIS

Based on the detailed geological investigation of the landslide in the ZuDong area of Longnan County, the detailed geological investigation of the study area was carried out, and the influence of the engineering geological rock group, slope, slope elevation, geological structure and human activities on the landslide was analyzed, the factors of landslide risk assessment were selected according to the factors of slope stability, the weighting information model was calculated by analytic hierarchy process. Area for landslide hazard assessment. The results showed that the artificial activities such as pool leaching, heap leaching and in situ leaching of rare earth mines had the greatest impact on landslide hazard, and the slope and the slope were the least affected. The rare earth mine slope should be the key landslide control and monitoring in the study area.
