该数据集主要由三个部分组成：网站数据（GNIR数据，http://nucleus.iaea.org/wiser/explore，水同位素网站，http://wateriso.utah.edu/waterisotopes） 、测量数据和参考数据。该数据集涵盖了分布于七大洲的22432个地表水采样点。自2015年起，在中国西北干旱区石羊河流域实施了生态水文观测系统，系统性地收集地表水稳定同位素数据，作为测量数据的主要来源。

The Dataset consists of three main elements: website data (GNIR data, http://nucleus.iaea.org/wiser/explore, water isotopes website, http://wateriso.utah.edu/waterisotopes), measured data and references data. The dataset encompasses 22432 surface water sampling sites across seven continents (Fig.1). Since 2015, an ecohydrological observation system has been implemented in the Shiyang River Basin in the arid zone of Northwest China to systematically gather surface water stable isotope data, serving as the primary source of measured data.
