摘要
本文以新疆吉木乃矿山崩塌地质灾害为研究对象,选取8类评价指标,将证据权法结合GIS空间分析功能,进行加权叠加分析,构建矿山崩塌地质灾害易发性评价体系,对矿山崩塌地质灾害易发性进行评价。利用ROC曲线得到的AUC值为0.785,表明该方法具有较好的评价精度,可为矿山崩塌预警和防治规划提供技术参考。
This paper takes the collapse geological hazards of Jimunai mine in Xinjiang as the research object,chooses eight kinds of evaluation indicators,combines the evidence weight method with the spatial analysis function of GIS,carries on the weighted superposition analysis,constructs the mine collapse geological hazards susceptibility evaluation system,and evaluates the mine collapse geological hazards susceptibility.The AUC value obtained from ROC curve is 0.785,which shows that the method has good evaluation accuracy and can provide technical reference for mine collapse early warning and prevention planning.
