Application of ARCGIS and Analytical Hierarchy Process in the Risk Assessment of Geological Disaster in Complex Mountains

چکیده
Based on the precipitating factors of geological disasters in complex mountainous regions, this paper took geological disaster distribution, seismic intensity, fracture, engineering petrofabric, river distance, slope and precipitation as the risk indicators of geological disasters. Next, a mathematical model was established by using the analytical hierarchy process. The weight of above seven risk indicators and the coincidence indicator were determined by MATLAB programming which has satisfying calculation accuracy and reliability. Finally, the ARCGISbased spatial calculation and analysis disclosed the risk assessment result of geological disasters in the research area. The results demonstrated good effect of the evaluation model and programming based on the combination of analytical hierarchy process and ARCGIS in the risk assessment of geological disasters in complex mountainous region. This can provide some references to similar assessment.
