摘要
基于层次分析法,选取12个评价因子构建了地质灾害危险性评估模型,并对12个评价因子及其种类的判断矩阵和权重及CR、λ_(max)进行计算。另外,利用成功率曲线和ROC曲线评价模型的有效性和准确率。根据危险性评估结果,对危险区进行划分。根据判断矩阵的计算结果和一致性检验,CR小于0.1,每个评价因子的判断矩阵均拥有较好的一致性,能通过一致性的检验。研究结果表明,层次分析法能较客观、准确地对地质灾害的危险性进行评价。
Based on the analytic hierarchy process, this paper selects 12 evaluation factors to build a geological hazard risk assessment model, and calculates the judgment matrix and weight of the 12 evaluation factors and their types, as well as CR and λ_(max). In addition, the effectiveness and accuracy of the model were evaluated using the success rate curve and the ROC curve. According to the results of the risk assessment, the danger zone is divided.According to the calculation results of the judgment matrix and the consistency test, the CR is less than 0.1, and the judgment matrix of each evaluation factor has good consistency and can pass the consistency test. The research results show that the AHP can more objectively and accurately evaluate the risk of geological disasters.
