- Abstract:
-
Correlation of salt ions and salinization types of soil around different distance ranges from Halogeton Glomeratus were studied by using Halogeton Glomeratus of halophyte widely distributing in Minqin Oasis as the research example. The results showed that 0—60 cm distance from the Halogeton glomeratus in the horizontal direction, anion component of 0—40 cm soil layer belonged to chloride-sulfate type and belonged to chloride-sulfate type in 40—60 cm soil layer, cation component in 0—40 cm soil layer belonged to calcium-sodium type, and belonged to sodium type in 40—60 cm soil layer. Pearson correlation analysis and partial correlation analysis had clear difference among salt ions of Halogeton Glomeratus surrounding 0—60 cm range soil. Partial correlation analysis could more exactly reflect the correlation between two variables in multivariate, therefore, it was suggested that partial correlation analysis should be used when studying a correlation between similar salt ions. The partial correlation analysis of salt ions in soil around Halogeton glomeratus showed that in the horizontal direction away from the Halogeton glomeratus 20 cm and 40 cm, SO42- and Na+ had the highest correlation with soil total salinity. In the horizontal direction away from the Halogeton glomeratus 60 cm, Cl- and Na+ had the highest correlation with soil total salinity. Thus, in the horizontal direction away from the Halogeton glomeratus 0—60 cm range, soil salinity mainly resulted from sodium chloride,calcium chloride, sodium sulfate and calcium sulfate.
