外文摘要： Hydrodynamic dispersion experiment was done with unsaturated silt loam。 Depend on mass conservation law， theformulas to calculate coefficient of hydrodynamic dispersion was developed。 According to the data of soil water and salt regimemeasured from the upright soil column， the coefficient of hydrodynamic dispersion was calculated， and the relation betweenhydrodynamic dispersion and average flow velocity in soil voids was built up。 This approach has clear concept of physics， and theformulas are simple and applied。
