Determination of relationship between soil characteristics and plant species densty in Aras Riparian Zone

Present Study was done for distinguishing of relationship between soil characteristics and Plant species densty in Aras Riparian Zone. For this purpose, 20 plots(10×10 m) were selected using randomized systematic sampling and density vegetation and crown cover, diameter and elevetion of native species were recorded. The result of χ2 test showed that different soil textures significantly (p<0.05) have different presence and density of species.Whereas Tamarix ramisissima as compared with other species have the highest presence in bothe soil textures, Loam and Sandy-Loam(%89/7and%74/85). The highest occureance of Eleagnus angustifolia, Salix alba and Populus alba were in Sandy-Loam textures. Correlation cofficients of evaluated parameters showed that study factors of species had different correlation with determined factors of soil. Whereas the soil characteristics significantly (p<0.01) have different correlation with density of Tamarix ramisissima. All the soil characteristics significantly have a positive Correlation with density of Tamarix ramisissima, except pH.
