| Abstract: | To study the response characteristics of the distribution of inland salt marsh plant communities to soil salinity,the Ordos salt lake and salt marsh area was selected as the research area,and three typical plant communities were screened for the succulent salt-tolerant plant community,including the succulent plant,the Carex plant community and the Gramineous grass plant community.The soil water content,pH,electrical conductivity and the concentrations of Na+,K+,Mg2+,Ca2+,Cl-,O42-、O32-and HCO3-were measured for the response of typical plant communities in the area to soil water and salt factors.The differences in the soil factors among the three types of plant communities were discussed;correlation analysis and CCA analysis were used to evaluate the changes in the diversity and species distribution of the three types of plant communities with soil factors.The results showed that among the three types of plant communities in the area,the soil salt content was the highest in the succulent salt-tolerant plant community,the Carex plant community was the lowest,and the gramineous grass plant community was in the middle;the plant diversity was correlated with the content of Na and O42-in the soil.Plant distribution is also significantly affected by soil salinity,moisture and pH.The research results can provide theoretical support for soil salinization improvement and vegetation restoration in the Ordos salt lake area. |
