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

This 1∶50 000 hydrogeological survey results dataset was created as a result of the CGS (Chinese Geological Survey) project ‘Hydrogeological Survey (1∶50 000) of the Plain Area of the Baiyang 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 Xiong’an 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 Baiyang Lake and its surroundings, evaluating groundwater resources and investigating problems relating to the eco-geological environment, such as degradation of wetland ecological functions.
