| Abstract: | 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. |
