雄安新区白洋淀流域平原区1∶50 000水文地质数据集

This 1:50 000 hydrogeological survey dataset was created as a result of the CGS (China Geological Survey) project "Hydrogeological Survey (1:50 000) of the Plain Area of the Baiyangdian Lake Basin" in 2016, building on previously collected geological information. It was prepared in accordance with industrial specifications, using data acquired through this survey by conducting a 1:50 000 hydrogeological and specifically eco-environmental geological survey in the Anxin and Xiong Counties, both located within the core planning and building region of Xiongan New Area, and by preparing a standard 1:50 000 hydrogeological map with instructions for its use. This dataset has 8 types of data, including 895 basic survey data, 22 data from combined geological field survey points, 82 data from stratum lithological boundary survey points, 540 data from hydrogeological survey points, 22 data from environmental geological survey points, 12 data on basic information from drilled boreholes, 71 data from comprehensive results of pumping tests and 2 200 data from field pictures, in total 3 844 data. This dataset has implications as a reference work that are critical to understanding hydrogeological conditions in Baiyangdian Lake and its surroundings, evaluating groundwater resources and investigating problems relating to the eco-geological environment, such as degradation of wetland ecological functions.

本1:5万水文地质调查数据集，系2016年中国地质调查局（China Geological Survey，CGS）“白洋淀湖盆平原区1:5万水文地质调查”项目成果，依托前期收集的地质资料编制而成。本数据集严格遵循行业规范，通过在雄安新区规划建设核心区域内的安新县与雄县开展1:5万水文地质及专项生态环境地质调查获取相关数据，并同步编制了标准1:5万水文地质图及其使用说明。本数据集共包含8类数据，总计3844条，具体包括：基础调查数据895条、联合地质野外调查点数据22条、地层岩性边界调查点数据82条、水文地质调查点数据540条、环境地质调查点数据22条、钻孔基础信息数据12条、抽水试验综合成果数据71条，以及野外实拍照片数据2200条。本数据集可为白洋淀湖域及周边地区水文地质条件认知、地下水资源评价，以及湿地生态功能退化等生态地质环境问题调查提供关键参考依据。
