湖北省蒲圻县 (赤壁) 幅 1∶ 50 000 环境地质调查数据集

The environmental geological survey on a scale of 1:50 000 in the Puqi Map Sheet (also referred to as the Survey) was carried out by relying on the project titled Environmental Geological Survey on a Scale of 1:50 000 in the City Clusters of the Middle Reaches of the Yangtze River Along Xianning-Yueyang and Nanchang-Huaihua High-speed Railway initiated by the China Geological Survey. The dataset obtained through the Survey (also referred to as the Dataset) was developed by methods such as the hydrogeological survey, karst collapse survey, hydrogeological drilling and water-quality testing and analysis. It consists of the data of 73 spring survey points, test and analystical results of mineral water from 7 water samples and the data from 1 karst collapse point, 7 karst cave points and 10 hydrological boreholes. The detailed contents of these data are as follows:the results of the spring water survey include locations of spring survey points, water quality indices to be tested in the field and the genesis of spring water. The analytical results of mineral water are the ones reaching the requirements of mineral water according to the indoor testing of water samples taken from spring points and hydrological boreholes in the Puqi County Map Sheet. The data of karst collapses mainly include location of karst collapses, features of collapse pits, geological background and the state after collapse. The survey results of karst caves include the location, development features and development and utilization of the caves. The data of boreholes contain the location, diameter and depth of the boreholes. The Dataset will provide an important geological source for the planning and construction of towns, safe utilization of land and the development of high-quality geological resources in Chibi City.

蒲圻县图幅（Puqi Map Sheet）1:5万环境地质调查（以下简称本调查），依托中国地质调查局（China Geological Survey）发起的《长江中游城市群咸宁-岳阳、南昌-怀化高铁沿线1:5万环境地质调查》项目开展。本调查所获取的数据集（以下简称本数据集），通过水文地质调查、岩溶塌陷调查、水文地质钻探及水质测试分析等方法构建，包含73处泉点调查数据、7件矿泉水水样的测试分析结果，以及1处岩溶塌陷点、7处溶洞点和10处水文钻孔数据。各类数据具体内容如下：泉点调查成果涵盖泉点位置、野外待测水质指标及泉水成因；矿泉水分析成果为蒲圻县图幅内泉点及水文钻孔采集的水样经室内测试后，符合矿泉水水质标准的分析结果；岩溶塌陷数据主要包括塌陷点位置、塌陷坑特征、地质背景及塌陷后状态；溶洞调查成果涵盖溶洞位置、发育特征及开发利用情况；钻孔数据包含钻孔位置、孔径及孔深。本数据集将为赤壁市城镇规划建设、土地安全利用及优质地质资源开发提供重要的地质数据支撑。
