【Abstract】 The theory and application of hydrogen and oxygen stable isotopes in soil evaporation are introduced in this paper.The effects of the presence of salt,temperature gradients,soil water transport mechanisms,different soil horizons and vegetation on soil evaporation mechanisms and their computational methods are analyzed.The characteristic of hydrogen and oxygen stable isotopes fractionation in soil evaporation reveals the soil evaporation mechanisms.At the end of this paper,the importance of choosing appropriate soil water extraction techniques,the limitation of soil evaporation studies and the future research focus are pointed out.更多还原
