摘要:
本数据集为2017年在海南省龙门市幅开展的1∶50 000环境地质调查的调查信息、水文地质钻孔、地下水采样及化学成分测试结果，包含机民井点221个，泉点21个，地表水点7个，水文地质钻孔10个，进尺808.77 m，地下水全分析采样点56个。调查点符合规范要求，钻探施工质量可靠，采样过程规范，测试均由符合资质要求的实验室完成，数据质量可靠。数据集可以真实反映该时段龙门市幅水文地质环境地质条件，并依托调查成果，为地方圈定1处地下水后备水源地，可有效缓解季节性缺水问题，为科学合理利用地下水资源提供依据。
Abstract: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.
