Study on Spatial Variability of Soil Infiltration Properties in Yucheng District of Shandong Province

Spatial variability of the steady water infiltration rate and infiltration experiential index is studied with traditional statistics and Geo-statistics.The results show that both steady water infiltration rate and infiltration experiential index obey lognormal distribution.The soil property is imbued with spatial variation-structure,but it's not perfect for random variation,and there exists spatial correlation phenomenon in a limited range.The authors also use the Kriging interpolation technique to estimate the steady water infiltration rate and infiltration experiential index spatial distribution over the entire plot area.
