Based on the Pisha sand stone in the Inner Mongolia ZhunGeErQi as the research object, in this paper, through the field sampling of undisturbed soil and laboratory simulation of soil-column experiment, soil water infiltration were analyzed by one-dimensional vertical infiltration experiment to study the process of water infiltration on the loess soil, aeolian sandy soil and Pisha sand stone. The results showed that the infiltration rate and cumulative infiltration changed trend was: aeolian sandy soil＞loess soil＞Pisha sand stone in the undisturbed soil, and aeolian sandy soil＞Pisha sand stone＞loess soil in the disturbed soil. The wetting front and the cumulative infiltration showed the same trend both in the undisturbed and disturbed soil. Fitting the relationship between infiltration rate and time with Kostiakov empirical formula, Philip model and Green-Ampt equation, the results showed both Kostiakov infiltration equation, Green-Ampt and Philip equation were suitable for simulating the change of cumulative infiltration capacity for the disturbed and undisturbed soils, but Kostiakov formula was more accurate fitting the water infiltration on the disturbed and undisturbed soil than other models.
