摘要
本文以淮南市大通区北部丘陵为研究对象,基于遥感数据提取和地理信息系统(GIS)空间分析技术,结合综合指数法与层次分析法,对该区域的崩塌易发性进行评价。选取坡度、高程、工程岩组、地质构造、斜坡结构5项地质环境因素作为评价因子,通过层次分析法确定权重,并利用综合指数法进行计算。结果表明,崩塌易发性主要分布在高程大于200 m、坡度大于15°的区域,且多位于地貌起伏的山地。低易发区面积为2.76 km2,占研究区面积的14.1%,非易发区面积为12.15 km^(2),占研究区面积的85.9%。模型精度指标小于0.1,符合真实情况,表明基于遥感与GIS技术的崩塌易发性评价结果可靠。
This study focused on the northern hilly area of Datong District,Huainan City.Using remote sensing data extrac⁃tion and geographic information system(GIS)spatial analysis technology,combined with the comprehensive index method and analytic hierarchy process(AHP),the collapse susceptibility of the region was evaluated.Five geological environmental factors—slope,elevation,engineering rock group,geological structure,and slope structure—were selected as evaluation fac⁃tors.The weights were determined using AHP,and calculations were made using the comprehensive index method.The results show that collapse susceptibility is mainly distributed in areas with an elevation greater than 200 m and a slope greater than 15°,most of which are located in mountainous areas with undulating topography.The low susceptibility area covers 2.76 km^(2),accounting for 14.1%of the study area,while the non-susceptible area covers 12.15 km^(2),accounting for 85.9%.The model’s accuracy index is less than 0.1,which aligns with the real situation,indicating that the collapse suscep⁃tibility evaluation results based on remote sensing and GIS technology are reliable.
