| Abstract: |
| To investigate the correlation between soil nutrients
and salinity characteristics in Bohe River riparian in Ebinur Lake, total salt content, eight ions content and soil nutrients in different types of vegetation were measured by using correlation analysis and principal component analysis. The results showed that:(1)over all, soil nutrients showed moderate spatial variability, except for potassium and available nitrogen, the other nutrients parameters were stable; The coefficient of variation of soil salinity showed a significant spatial variability;(2)There were obvious correlation between organic matter, total K, available nitrogen and the principal component; There were obvious correlation between potassium and the second principal component; Organic matter, total K, available nitrogen, and potassium
could be served as characteristie faetors of the soil nutrients study. The results showed, in the researeh area, organic matter and total K were extremely poor, available nitrogen and potassium were relatively poor by soil nutrient elassification standard;(3)There were significant positive correlation between total salt content and contents of Ca2+、Mg2+、Cl-、K++Na+; Content of Ca2+、Mg2+、Cl-、K+ and Na+ were used as characteristies factors of salinization study. By salinization
classification standard, soil in the research area was classified as saline. |
