Relationship of salt-resistant hemicryptophyte species in proportion to edaphic factors in coastal desert near Persian gulf

Changes in different solute compounds in edaphic factors affect the spatial distribution of plant species, especially hemicryptophytes.Soil salinity is one of the most common desertification factors in arid and semi-arid regions that contributes to the degradation of the soils of regions susceptible to desertification and eventually leads to a decreased soil ecological potential which is considered as one of the most significant factors that intensifies desertification. In order to explore the impact of principal components of soil on the diversity of plant types in the forest regions scattered along the coastal belt of the Persian Gulf and Oman Sea, current research was conducted on saline soils in Hasan Langi Village. Analysis of correlation coefficient between different traits of the plants in the respective vegetation (percentage of coverage, height and density and diversity) and the soil parameters of the habitats indicated that these vegetative parameters were mostly correlated with acidity, texture, and total calcium and magnesium. Principal component analysis (PCA) demonstrated that components 1 and 2 explained a total of 85% variance suggesting the largest impact of soil factors on differentiation of vegetation. In total, the factor of diversity was most correlated with calcium and magnesium in the second depth while other vegetative characteristics were directly correlated with the amount of sodium and potassium as well as electrical conduction in the first depth and the amount of calcium in the second depth.
