Analysis on landslide hazards based on spatial information

GIS ( Geographic Information System)-baded three-dimension limit equilibrium model is used to analyze the stebility of potential landslide body in this article; The result of the improved unidirectional flow analysis is applied to confirm the then surge hazards when the landslide happens, in the upper reaches of reservoir. Then the influence range of the surge hazard can be visualized in GIS. The result of the study could provide the risk assessment of the potential landslide with an effective and reliable decision-support.
