摘要
Based on analyzing the geological environment, types and developing features of geological hazards in Lanzhou City, it has been employed analytic hierarchy process to establish the evaluating system. On the basis of index analysis and data normalization, and through the raster calculation function of ArcGIS System, all of relative weights determined by analytic hierarchy process for each evaluating factor have been made the process of information mixing to get a calculated raster map of quantitative probability of geological hazards in Lanzhou
