In this paper, a heterogeneous soil column was constructed in our laboratory. The column contained two kinds of homogeneous soils, which were of different texture, and was successfully constructed in the Ⅲ-shaped cross-section distribution of sandy loamy and loamy clayey soil using special shape soil partition.The heterogeneous soil column (50cm×50cm×40cm) was irrigated with 0.027mol/L CaCl₂ solution till steady water flow in soil column occurred. The effluent was collected every 5 minutes. The data was simulated using transfer function model. The probability density functions of the logarithm of travel time of chloride were calculated, and the model parameters (i. e. mean and deviation) were obtained. In addition, the transport volumes of chloride, the volume-averaged resident concentrations of chloride in the soil solution and other parametric values were obtained. To make a comparison between the deterministic and stochastic models, the breakthrough curves in homogenous soils were also plotted and simulated by the convection-dispersion equation.
