该数据集包含三个主要部分：网站数据（GNIR数据，http://nucleus.iaea.org/wiser/explore；水同位素网站，http://wateriso.utah.edu/waterisotopes）、实测数据及参考文献数据。该数据集覆盖七大洲共22389个地表水采样点。自2015年起，中国西北干旱区石羊河流域实施生态水文观测系统，系统性收集地表水稳定同位素数据，构成实测数据的主要来源。同位素数据v1.1版本的改进主要在于剔除部分重复及错误数据。", "ds_source": "

This dataset consists of three main parts: website data (GNIR data, http://nucleus.iaea.org/wiser/explore Water isotope website, http://wateriso.utah.edu/waterisotopes ）Actual measurement data and reference literature data. This dataset covers 22389 surface water sampling points across seven continents. Since 2015, the Shiyang River Basin in the arid northwest region of China has implemented an ecological hydrological observation system, systematically collecting stable isotope data of surface water, which constitutes the main source of measured data.
