Susceptibility Assessment of Slope Geological Hazards in Naidong District Based on GIS
Taking Naidong District of Tibet Autonomous Region as the study area,the geological conditions conducive to disasters in the region were analyzed by using the AHP-Information method.Eight evaluation factors were selected,including engineering geological rock formations,distance to faults,human engineering activities,distance to water systems,slope gradient,slope height,slope structure,and vegetation.Based on the ArcGIS platform,the susceptibility to landslides and collapses in Naidong District was evaluated,and the results were classified into four levels:high,medium,low,and non-susceptible.The evaluation accuracy was tested using the ROC curve,which showed good performance.This study provides a scientific basis for the prevention and control of slope-related geological disasters in Naidong District.
