针对龙南县足洞地区滑坡地质灾害,对研究区进行野外详细地质调查,分析工程地质岩组、坡度、边坡高程、地质构造及人类活动等对滑坡的影响,结合斜坡稳定性影响因素选定滑坡危险性评价因子,采用层次分析法计算加权信息量模型并利用ArcGIS软件对研究区进行滑坡危险性评价分区,得到研究区滑坡灾害危险区划分图及相关统计信息,结果表明:区内稀土矿山的池浸、堆浸及原地浸矿等人工活动对滑坡灾害影响最大,高程及坡度其次,坡向影响最小,稀土矿山采场应作为研究区重点滑坡防治及监测区域,评价结果与研究区实际情况一致性较好.%Based on the detailed geological investigation of the landslide in the ZuDong area of Longnan County, the detailed geological investigation of the study area was carried out, and the influence of the engineering geological rock group, slope, slope elevation, geological structure and human activities on the landslide was analyzed, the factors of landslide risk assessment were selected according to the factors of slope stability, the weighting information model was calculated by analytic hierarchy process . Area for landslide hazard assessment. The results showed that the artificial activities such as pool leaching, heap leaching and in situ leaching of rare earth mines had the greatest impact on landslide hazard, and the slope and the slope were the least affected. The rare earth mine slope should be the key landslide control and monitoring in the study area.
