通过野外调查分析了新疆民丰县地质灾害发育规律,运用层次分析法(AHP)建立地质灾害易发性评价结构模型及判断矩阵,用以确定影响地质灾害易发程度的各因素权重,建立区域地质灾害易发性评价的数学模型,并得出基于GIS平台的区域地质灾害易发性预测分区图。通过对比野外调查灾害隐患点分布情况,证明该方法比较合理,预测结果与实际地质灾害发育区的拟合率大于80%。
Through field investigation and analysis, the rule of geological disasters in Minfeng County of Xinjiang Autonomous Region was analyzed. Analytic hierarchy process (AHP) was used to establish the structural model and judgment matrix of susceptibility to geological disasters to determine the weight of each factor affecting the vulnerability of geological disasters and to establish regional geology Disaster proneness evaluation mathematical model, and the GIS-based regional geological disasters susceptibility prediction zoning map. By comparing the distribution of disaster hidden danger points in field survey, the method is proved to be reasonable, and the fitting rate of prediction results to actual geological disaster development zone is more than 80%.
