A case study on the relationship between soil geochemical components and salinization in the west Jilin province of China

Abstract

In this paper, we conducted a case study on the relationship between the soil geochemical components and the occurrence of soil salinization in the west of Jilin Province in China employing the GIS technologies and statistical analysis. We found that (i) the geochemical components are closely correlated with soil salinization and (ii) the selected eighteen geochemical components, S, K, Be, Cu, MgO, CaO, Na 2O, Ph, Eh, Ba, Sb, F, Tl, Sr, Th, Pb, Se, Ge, were characterized with hierarchy and could be restructured into ten determinant factors after a CLUSTER and FACTOR analyses. In addition, this paper developed a binary logistic model with the occurrence or without occurrence of soil salinizat..
