中文摘要：

综述了国内外同位素水文学研究的主要成果，认为同位素示踪方法在解决某些水文、水资源及环境地质问题方面优势比较明显，并且有助于从宏观和微观上阐明水循环过程中各相关要素的变化情况，揭示某些水文基本现象的内在规律；指出了同位素水文学研究当前存在的问题和今后的一些重点课题，并对同位素技术或方法在水文学中的应用前案进行了展望。

英文摘要：

The progress of isotope hydrology at home and abroad was reviewed. The isotopic tracer techniques were regarded to be of obvious superiority in solving problems concerning hydrology, water recourses and environmental geology, etc. It would help to illuminate variation of various hydrologic elements during water cycle process from both the macroscopic and microscopic viewpoints and to discover the inherent laws of some hydrological phenomena. The existing problems in researches on isotope hydrology at present as well as relative important topics in future were highlighted, and the prospects of the application of the isotope techniques or methods in hydrology were put forward.
