| 摘 要： | 在详细分析延安黄土丘陵沟壑区的地形地貌类型、斜坡的坡体结构、地质灾害类型的基础上,利用1:1000地形图为底图进行地质灾害的易发区划分分析。结果表明,对该区居民生命财产安全造成重大威胁且防范困难的地质灾害类型为不稳定斜坡(黄土滑坡、黄土崩塌、基岩崩塌)隐患,黄土陡坡和基岩陡坎区地质灾害高且易发。

| Abstract: | Based on the analysis of the types of topography,the slope structures,and the geological hazards,within 1:1000-scale topographic maps,geologically disaster-prone areas were identified and divided into study zones.In the examined hilly gully region of the Yan''an Prefecture, the safety for life and property of the local residents were threatened by potential loess landslides, loess collapse,and rocky collapse from an unstable slope.However,the hazard from this unstable slope is difficult to prevent due to the presence of local residents and the steepness of the loess slope and rocky scarps.This study can provide certain reference for similar research in future. |
