The spatial variability of soil hydraulic properties influenced by topographic and soil physical and chemical factors is one of the key factors which have considerable effects on water flow and solute transport.An experiment was conduced on a 80m @ 40m plot.Saturated conductivity,Kfs,was measured at a depth of 30 cm,and soil physical and chemical properties were also considered,such as wetness index,bulk density,particle composition,organic matter,exchangeable sodium,CEC and ESP in the 24 sampling sites selected randomly.Based on classic statistics and the Kolmogorov) Smiromov(K)S) normality test,spatialst ructure was analyzed using the GIS+ for Window 5.The result indicated a normal distribution for Kfs,bulk density,organic matter,sand,clay and CEC,a lognormal distribution for exchangeable Na+ and ESP,and auniform distribution for silt.Kfs,bulk density,organic matter,sand,clay,exchangeable sodium and ESP showed the spatial correlation characteristic,but CEC had more distinct spatial heterogeneity than other factors.The influencing factors were also analyzed based on the correlation and PCA method.
