海南省龙门市幅 1∶ 50 000 环境地质调查数据集

The dataset of the environmental geological survey on a scale of 1:50 000 in the Longmen Map Sheet, Hainan Province in 2017 (also referred to as the Dataset) contains the survey information, data of hydrogeological boreholes, groundwater sampling information and the chemical component of the test results from the groundwater samples, which include 221 pumping (domestic) well points, 21 spring points, 7 surface water points, 10 hydrogeological boreholes, 808.77 m footage, and 56 groundwater full analysis sampling points. The data in the Dataset are credible since the survey points are consistent with applicable specifications, drilling quality is credible, the sampling conforms to relevant standards and the samples were tested in qualified labs. Therefore, the Dataset can faithfully reflect the hydrogeological and environmental geological conditions in the Longmen Map Sheet during the survey period. Furthermore, a backup groundwater source was delineated based on the survey results, making it possible to effectively alleviate the seasonal shortage of water and provide a basis for scientific and rational utilization of the groundwater resources.2017年海南省龙门幅1:5万环境地质调查数据集（以下简称本数据集）包含调查资料、水文地质钻孔数据、地下水采样信息及地下水样品测试化学成分结果，涵盖221个抽水（民用）井点、21个泉点、7个地表水点、10个水文地质钻孔，总进尺808.77米，以及56组地下水全分析采样点。本数据集数据可信，原因在于调查点位符合相关规范要求，钻孔质量可靠，采样流程符合相关标准，且样品均在具备资质的实验室完成测试。因此，本数据集能够真实反映调查时段内龙门幅的水文地质与环境地质条件。此外，基于本次调查结果划定了后备地下水源，可有效缓解季节性缺水问题，同时为地下水资源的科学合理开发利用提供依据。
