青海湖流域地下水、河水、湖水氢氧稳定同位素和水化学数据集（2019-2020）

本数据集包含青海湖流域融化期和冻结期地下水、河水、湖水的氢氧稳定同位素（δ2H、δ18O、δ17O）、水化学（pH、EC、TDS、TH、K、Ca、Mg、Na、HCO3）和矿物饱和度指数（SI）等指标。氢氧稳定同位素采用LGR液态水同位素分析仪测试。水化学离子采用便携式多参数仪、等离子电感耦合光谱仪、现场滴定等方法测试。矿物饱和度指数采用Phreeqc Interactive软件计算获得。该数据集样品采集及测试环节严格按照相关实验准则操作，数据可靠准确。该数据集可用于定量研究水循环及演变规律、水质、地球化学过程等，对区域水资源的科学管理和可持续发展具有重要意义。

This dataset contains indicators including hydrogen-oxygen stable isotopes (δ2H, δ18O, δ17O), hydrochemical parameters (pH, EC, TDS, TH, K, Ca, Mg, Na, HCO3), and mineral saturation indices (SI) of groundwater, river water and lake water in the thawing and freezing periods of the Qinghai Lake Basin. Hydrogen-oxygen stable isotopes were measured using a LGR liquid water isotope analyzer. Hydrochemical ions were tested via methods such as portable multi-parameter meters, inductively coupled plasma spectrometers, and on-site titration. Mineral saturation indices were calculated using Phreeqc Interactive software. Sample collection and testing procedures for this dataset strictly comply with relevant experimental guidelines, ensuring reliable and accurate data. This dataset can be used for quantitative research on water cycle and its evolutionary patterns, water quality, geochemical processes and other related topics, and is of great significance for the scientific management and sustainable development of regional water resources.
