Abstract:
The semivariogram and cross-semivariogram of soil water content of 20 cm and 55 cm were analysed. The optimal interpolation of soil water content by Kriging and Cokriging was calculated. It isshown that the interpolation precision of Kriging method is higher than that of Jackkniffing and linear methods,the precision of Cokriging method is higher than that of above methods. The upper layer soil water content value can be used to improve the interpolation precision of deeper layer soil water content.
