Study on the Evaluation Methodology of Landslide Susceptibility Based on Spatial-scale Analysis

Abstract

Landslides are significant natural geological hazards. Landslide susceptibility evaluation involves the quantitative assessment and prediction of potential landslide locations and their probabilities. Research has explored susceptibility assessment methods based on spatial-scale analysis. This evaluation integrates two models—global and local scale—using a CNN model and a PSO-CNN coupled model. Key aspects include selecting evaluation factors and optimizing model parameters for landslide susceptibility at different scales. A major focus of current landslide research is utilizing prediction results to enhance prevention and control measures.
