1：50000奉节县幅灾害地质图数据集

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∶50000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。

Fengjie County, a county with high incidence of geological disasters in the Three Gorges Reservoir Area of China, features undulating terrain, well-developed structures and weak rock strata, and a relatively fragile geological environment. Through field geological surveys carried out in the study area, the distribution patterns of geological disasters and the geological background for disaster genesis within the region were clarified. By integrating data including disaster-related, geological and geographic information, the 1:50000 geological hazard map for the Fengjie County sheet was compiled for the first time, and the corresponding dataset was established. This paper sorts out and summarizes the work from the aspects of data sources, data collection methods and processing technologies, aiming to present an application example of the geological hazard map dataset in the field of geological hazard survey, so as to provide references for this type of geological survey, dataset processing and application.
