The analysis of soluble salt in soil is an important foundation work in research of salt dynamic monitoring of salinized soil and prevention of soil salinization.This paper studied the spatial variability of salinization by geo-statistics method,and made the spatial distribution map of salt contents by using Kriging method.The results indicated that except Cl- and Ca2+ belongs to strong spatial variation of strength, other ions possess moderate spatial variation of strength; apart from Ca2+ and total salt ,other salt ions exhibit moderate spatial correlation and shows little difference in the autocorrelation distance of each salt ion due to the joint action of structural and stochastic factors; the spatial structure of most salt ions is good as showed in Kriging interpolation maps,ions content in the middle was significantly lower than that in other directions. The results can provide theoretical basis for the prevention, improvement and utilization of salinized soil in the irrigation region of Kongque river.
