摘　　要：近几十年来,稳定同位素技术在流域生态水文研究中的应用日益广泛。文中重点综述了氢氧稳定同位素技术在大气降水水汽来源、径流分割、流域产流方式划分、非饱和带土壤水分运移、植物水分利用、不同水体相互转化及同位素水文模型等方面研究应用的最新进展,分析其存在的问题,展望该技术在流域生态系统水文过程研究中的应用前景和发展方向。Over recent decades,stable isotope technology has been widely applied in watershed hydrology.The paper reviews the latest research progress in the application of stable isotope techniques to precipitation water vapor source,hydrograph separation,the division of watershed runoff patterns,plant water use,soil water transport in unsaturated zone,the transformation of different water bodies,and isotopic hydrological models,and discusses the currently existing problems in the research on watershed hydrology.At the end,the application and development of the technology in watershed hydrology are prospected.
