Abstract: Spatial variation pattern of water movement parameters in unsaturated soil is the base of parameter estimation in a large area.Analysis of the spatial variation pattern of soil physical properties and water movement parameters in Qingwangchuan Irrigation Area,showed that the calibration coefficients of soil moisture characteristic curves and hydraulic conductivity were in a logarithemic distribution. They both had the linear relationship with the dry density and clay content of soil.F-test showed that the correlationship was significant.
