Abstract: 
One of the most important problem facing human corelization is desertification phenomenon. Saline areas are developing in desert lands. Plants in saline areas have adapted themselves to salinity stress. To avoid desertification and saline areas, it is necessary to investigate the ecosystem elements and their relationships in saline areas. In the latter, soil factors affect plant growth and development. In this study, plant species and density and soil salinity and texture were investigated at a constant slope. There was a significant relationship between plant density and distribution. Different species showed different degrees of tolerasnce to soil salinity and they ranged from very tolerant to non-tolerant species. Very tolerant species were found at the center of saline areas and non-tolerant at the edges. Among tolerant species, Holacnemum strobilaceum showed a maximum tolerance and they can be used for control of saline areas were as Gymnocarpus decander was found to be suitable for the edges of salines areas inorder to avoid salinity development.
