雄安新区白洋淀流域平原区1:50000水文地质数据集

Dataset of the 1:50 000 Hydrogeological Map of the Plain Area of the Baiyangdian Lake Basin, Xiongan New Area

本数据集依托2016年中国地质调查局'白洋淀流域平原区1:50 000水文地质调查'项目,在充分收集以往地质资料的基础上,开展了隶属雄安新区规划建设核心区域的安新县幅、雄县幅1:50 000水文地质及专项生态环境地质调查工作,编制了标准的1:50 000水文地质图及说明书,依照行业规范将此次调查获取的数据建立了1:50 000水文地质调查成果数据集。本数据集包含8种数据类型,包含895个基础调查数据,22个野外地质综合调查点数据,82个地层岩性界限调查点数据,540个水文地质调查点数据,22个环境地质调查点数据,12个钻孔基本情况数据,71个抽水试验综合成果数据,2 200个野外照片数据,共计3 844个数据。本数据集对认识白洋淀及周边区域水文地质条件,评价地下水资源,以及研究湿地生态功能退化等生态地质环境问题具有一定的参考意义。

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.
