Abstract: The selection and determination of soil hydraulic parameters is the basis of predicting water movement and solute transfer in soils. Based on the researches at home and abroad, the models of hydraulic parameters, including those of soil water characteristic curve and soil hydraulic conductivity, and their direct and indirect measurement methods were reviewed, and their application and limitation were compared to provide evidence for the selection and determination of soil hydraulic parameters in the study of ecological environment construction and sustainable agriculture development.

Key words: Soil hydraulic parameters, Model, Soil water characteristic, Soil hydraulic conductivity
