Kenli County, located at Yellow River Delta, has abundant land resources but with low utilization rate due to the serious inhibition of stern soil salinization which leads to great spatial variation of soil physical and chemical properties. This paper studied systematically the path relationships between soil salt and chemical parameters and the spatial variation characteristics of salinity parameters of 0-20 cm and 20-40 cm soils in Kenli County by the methods of field soil sampling and laboratory chemical analysis. The results showed that salinity of 0-20 cm soil was higher than that of 20-40 cm soil. Except for pH, the variation coefficient of the other studied chemical parameters of the two layer soils were all above medium variant. Cl^-, Na⁺ and Ca²⁺ had significant linear correlation with electrical conductivity (EC_5:1), indicating they were the direct influential factors on soil salinity. 0-20 cm soil showed strong salinization and sodication along the costaline, both EC_5:1 and SAR of 20-40 cm soil were less than topsoil, meaning less soil salinization and sodication. pH in 0-20 cm soil was higher than that of 20-40 cm soil, meaning higher alkalization. The above results can provide not only reliable data bases and empirical formula for soil salinity study but also scientific basis and theoretical guidance for soil salinization control in Kenli County.
