本文从影响土壤水稳定同位素变化的因素、时空变化规律以及“土壤-植物-大气”界面水分转化和循环过程等方面综述了国内外土壤水同位素研究的主要成果,认为同位素方法在研究土壤水运移、江水入渗及土壤蒸发问题上优势比较明显,并且有助于从红挂和微观上阐明土壤水的特征及其运动规律;指出了当前土壤水分同位素研究粗在的问题何今后研究的重点,并对同位素技术与方法在土壤水中应用前景进行了展望。
This paper summarized the main advances in soil water isotopes by reviewing the influential factors on the changes in soil water stable isotopes, spatial and temporal variation and water transformation and cycle processes at the "soil - plant - atmosphere" interface. Isotopes had obvious advantages in the investigation of soil water movement, rainfall infiltration and soil evaporation and could clarify the macro and micro characteristics and movement of soil water. This paper also indicated the current problems and the future focus in soil water isotope study and prospected the application of the isotope technology or method in the soil water.
