| Probability Assessment of Mountainous Hazards in Lingyuan City, Liaoning Province |
| Lingyuan City lies in western Liaoning Province with severe mountainous geological hazards. Based on GIS, the authors selected six indices, i.e., topography, lithology, structure, rainfall, land-use and road, for the assessment, and calculated the sensitivity of various indices according to 68 hazards that historically happened, with the weights of the factors determined by AHP. The synthetic appraisal of mountainous geological hazards in Lingyuan City was made by factor overlay. The result indicates that the distribution of mountainous geological hazards in Lingyuan area is of obvious zonality, and the highly-dangerous area is intimately related to regional tectonics and human activities with high frequency. The research is helpful to the prevention of mountain hazards in Lingyuan City. |
