This paper surveyed the soil resistivity and corresponding moisture content of the soil from a field of Qingdao City by using self-made equipments, and then established the parameters of resistivity-moisture model. Based Soil Water Retention Curve (SWRC) obtained from the “Ku/pF apparatus”, the relationship between resistivity and matric suction was constructed through moisture content, and the resistivity-matric suction model was proposed which would be an alternative method to predict the soil matric suction. Then, combined resistivity-matric suction model and resistivity-moisture model, the purpose of obtaining SWRC was achieved, which made it possible to predict SWRC on the regional scale spatially and temporally via the resistivity method.
