Collapse and Landslide Susceptibility Assessment of Geohazards Based on ArcGIS——Take Jungar Banner for Example
This paper takes Jungar Banner of Inner Mongolia Autonomous Region as the research area.Sev-en factors including elevation,aspect,slope,degree of relief,fracturing structure,engineering geological petro-fabric,NDVI were chosen as influencing factors the susceptibility of geohazards of collapse and landslide.Ana-lyze the influence of different factors on the susceptibility of geohazards of collapse and landslide by information value model based on ArcGIS information value model technique.And draw the susceptibility assessment map and the distribution map of the relationship between the influence factors and of geohazards with information value method.The study shows that the susceptibility of geohazards of collapse and landslide is related to the influence classification of disaster causing factors.This study can provide a reference for the assessment of the susceptibili-ty of geohazards of collapse and landslide in aeras with large area and small population,such as Jungar Banner.
