摘要
By investigating the element content changes and relationships among different elements, the paper discusses the geochemical distribution characteristics of the salinization region. A critical interval of pH value is involved in salinization soil, and the degree of salinization is closely related to the contents of C1, S, Na and other elements. The interaction of salinization and desertification are acted on the soil in the space, and these actions jointly caused the soil degradation in this area.
