Effects of planting on soil salt and water transport in silt loam soil were studied by means of big column experiment in the Laboratory of Water and Salt Regime,Fengqiu Agroecologic Experimental Station,Chinese Academy of Sciences. Models of soil salt and water transport were developed separately.Also,parameters such as saturated transmissibility(Hs),hydraulic conductivity(K),water characteristic curve h(θ)and coefficient of soil hydrodynamic dispersion(D)were measured indoors or in fields.The simulated and the measured results were analyzed and compared in detail,showing that the simulated results were very ideal.The rise of the groundwater table was of advantage to movement of salt and water in the silt loam soil column,which obviously leading to redistribution of salt in the soil column.As a result,the salt content of the soil at the depth of 20 cm was higher than that of the surface soil.So it is practicable to do numerical simulation of the soil salt and water transport by this model.Furthermore,if the actual movement of salt and water in fields should be described in detail,further study must be conducted.
