白洋淀流域地下水数据集

为研究白洋淀下游河流断流和地下水的补给的变化状态，作者于2009年6月在白洋淀流域采集了36个地表和地下水样本，并在此基础上经过标准化信息提取，得到白洋淀流域地下水数据集。数据采样点分别布置在流域的北部、中部和南部沿地下水流动方向。水流汇集的中部（社会人口活动相对集中）适当增加采样点的数量。样品分析测试由国土资源部地下水科学与工程重点实验室完成。白洋淀流域地下水数据集包括：（1）在ASTER GDEM数据基础上提取的白洋淀流域范围数据（Watershed_BYD）；（2）白洋淀水系数据（包括河流和湖泊）（River_Lake_BYD）；（3）白洋淀下游地下水等水位线数据（ContourWaterLevel_BYD）；（4）白洋淀地下水含水层2009年6月实测数据（包括：白洋淀湖水采样点、第一、第二、第三含水层采样点地下水水位埋深和氚含量数据）（SamplingData）；（5）1954 -2007年降水中的氚含量数据。数据集存储为.shp和.xlsx格式，压缩后数据量为318KB。本数据集的分析研究成果发表在《地理科学进展》34卷第3期。

To investigate the river drying-up status and changes in groundwater recharge in the lower reaches of the Baiyangdian Lake, the authors collected 36 surface water and groundwater samples from the Baiyangdian Lake Basin in June 2009. Subsequently, the Baiyangdian Lake Basin groundwater dataset was established via standardized information extraction based on these samples. The sampling points were arranged in the northern, central and southern parts of the basin along the groundwater flow direction. The central part where water converges (with relatively concentrated social and human activities) had an appropriately increased number of sampling points. Sample analysis and testing were conducted by the Key Laboratory of Groundwater Science and Engineering, Ministry of Natural Resources of the People's Republic of China. The Baiyangdian Lake Basin groundwater dataset includes: 1) Baiyangdian Lake Basin watershed boundary data (Watershed_BYD) extracted based on ASTER GDEM data; 2) Baiyangdian Lake Basin water system data (including rivers and lakes) (River_Lake_BYD); 3) Groundwater contour line data in the lower reaches of Baiyangdian Lake (ContourWaterLevel_BYD); 4) In-situ measured data of groundwater aquifers in the Baiyangdian Lake Basin in June 2009, including groundwater depth to water table and tritium content data from the Baiyangdian Lake water sampling points as well as the sampling points of the first, second and third aquifers (SamplingData); 5) Tritium content data in precipitation from 1954 to 2007. The dataset is stored in .shp and .xlsx formats, with a compressed size of 318 KB. The analytical and research findings based on this dataset were published in Volume 34, Issue 3 of *Progress in Geography*.
