    Dataset of Geo-Hazards in Fengjie Mapsheet (1: 50, 000), Chongqing

    • 摘要: 奉节县是中国三峡库区地质灾害高发区县,区内地形起伏,构造和软弱岩层发育,地质环境较脆弱,通过对研究区开展野外地质调查,查清了区内地质灾害分布规律及孕灾地质背景,整合灾害、地质和地理信息等数据,首次编制了奉节县幅1:50 000灾害地质图,建立数据集。本文从数据来源、数据收集方法、处理技术等方面进行了整理和归纳,以期呈现地质灾害调查领域灾害地质图数据集应用的实例,为该类型地质调查和数据集处理及应用提供参考。

       

      Abstract: Situated in China's Three Gorges Reservoir Region, the Fengjie County is prone to frequent geo-hazards. This area features big topographic relief, well-developed structures and soft rocks, and relatively fragile geological environment. This paper employs field geological surveys to ascertain the distribution regularities of geo-hazards and geo-hazard breeding geological setting in the studied area. The dataset of geo-hazards in Fengjie Mapsheet (1:50, 000), which has integrated the data in geo-hazard, geology and geography, has been constructed for the first time, along with the compilation of the same-scaled geo-hazard maps of Fengjie County Mapsheet. This paper has also classified the data sources, data collecting methods, and processing techniques, so as to provide practical application case of the geo-hazard maps dataset, and meanwhile present references for the data processing and application in this type of geological survey.
