Abstract: The spatial variability of the regional soil water infiltration is one of key issues now, yet there is no better ways to solve it.Based on the experiment data, the simplified Philip model of soil water infiltration and the pedo-transfer functions (PTFs) are established.By using ARCVIEW software, the distribution of infiltration parameters of the plain region of Shiyang river basin are drawed by these two models and the spatial characteristics are analyzed.The results indicate that the simplified Philip model is suitable for the study of transfer from points to region, the PTFs of the infiltration coefficient α can simply calculate the infiltration parameters, the combination of the simplified Philip model and the PTFs is the simple and beneficial method for the research of the spatial variability of the soil water infiltration characteristics of the large-scale region.
