The differential equation model of stable isotope composition in saturated soil water at evaporation condition based on the Fick law and the conservation of mass law was proposed.The boundary condition and initial condition were analyzed,and the analytic solution of the differential equation model was obtained.The model provides deterministic mathematic foundation for numerical simulation of saturated soil water stable isotope movement in the condition of evaporation,and are of important theoretical significance for soil water movement.
