This data is the observation and analysis point data of groundwater depth and water quality in the middle and lower reaches of Heihe River Basin. It mainly studies the hydrological cycle process and water quality change in the lower reaches of Heihe River. Data file: groundwater depth and water quality analysis data in the lower reaches of Heihe River Basin (2009-2013). XLS, including four tables: (1) water level burial depth of automatic observation well; (2) water level burial depth of patrol logging; (3) hydrochemistry; (4) isotope. This paper includes the data of groundwater level monitoring and automatic monitoring from 2009 to 2013 in the lower reaches of Heihe River, as well as the laboratory analysis data of water chemistry and hydrogen and oxygen isotopes of river water and groundwater samples. The results show that: 1) the depth of mineralization can be divided into three dimensions, i.e., the depth of mineralization can be divided into three dimensions, i.e., the depth of mineralization can be divided into three dimensions, i.e., the depth of mineralization can be divided into three dimensions, i.
Automatic monitoring of groundwater depth: the mini diver probe of Eijkelkamp company in the Netherlands is used, and the observation frequency is once every 30 minutes. Hydrochemical ion analysis: in the field, the water samples were measured with hi98188 Hanna portable waterproof EC / resistivity / TDS / salinity meter and cyberscan pc300 portable pH / EC meter for pH, EC, resistivity, TDS, salinity and temperature. The indoor hydrochemical analysis of water samples was completed in the physical and chemical analysis center of Institute of Geographic Sciences and resources, Chinese Academy of Sciences. Carbonate and bicarbonate were analyzed by titration (0.01nh2so4). Other cations and anions were determined by inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma spectrometer (ICP-OES). Hydrogen and oxygen isotope analysis: the water samples were analyzed by Finnigan mat-253 mass spectrometer in the Environmental Isotope Laboratory of Institute of Geographic Sciences and resources, Chinese Academy of Sciences.
This data sheet is manually entered by a specially assigned person according to the record book.
The observation and data collection are carried out in strict accordance with the instrument operation specifications, and have been published in relevant academic journals. The analysis of water samples is verified by cation anion balance calculation, and the experimental error is not more than 5%. In the process of generating data table, some obvious error data are eliminated.
