Spatial variability of some soil properties at a 20 m long hillslope on the Loess Plateau was studied with the classical statistical analysis. The results show that in the same soil profile

sand

silt and clay contents have small variability

and organic matter content decreases from upper layer to lower layer with moderate variability. Soil dry bulk density has small variability

but saturated hydraulic conductivity has moderate one. Soil water characteristic curve has some spatial variability and specific water capacity has moderate one. The isograms of soil saturated hydraulic conductivity and dry bulk density indicate that the change of soil saturated hydraulic conductivity does not only depend on soil dry bulk density

and has some relations with organic matter content

clay content and root distribution.
