| 中文摘要: |
| 本文以贵州省凤冈县为研究场，基于层次分析法(analytic hierarchy process，AHP)和信息量模型，选取高程、斜坡坡度、斜坡结构、地貌类型、距断层距离、距水系距离、距道路距离、工程岩组类型、剖面曲率、平面曲率等评价因子，计算出研究区综合地质灾害易发性信息量值。利用Arcgis108平台，通过自然间断点法将研究区信息量值进行分级得到低、中、高、极高易发区。ROC曲线对评价模型的精度，检验结果AUC值分别为0722、0703、0746，表明该方法对研究区地质灾害易发性评价效果良好且较为可靠。 |
| 英文摘要: |
| This article takes Fenggang county, Guizhou province as the research field. Based on the Analytic Hierarchy Process and information model, evaluation factors such as elevation, slope gradient, slope structure, landform type, distance from faults, distance from water systems, distance from roads, engineering rock formation type, profile curvature, and plane curvature are selected to calculate the comprehensive geological hazard susceptibility information value of the study area. Using the ArcGIS 10.8 platform, the information content of the research area is classified into low, medium, high, and extremely high risk areas through the natural discontinuity method. The ROC curve was used to evaluate the accuracy of the model, and the AUC values were 0.722, 0.703, and 0.746, respectively, indicating that this method has a good and reliable effect on evaluating the susceptibility of geological hazards in the study area. |
