Abstract:  

Known of ecosystem of range details and relation bet ween this details including soil and vegetation, is Necessary for optimum management of ranges. To determine the effect of some soil properties on species distribution of Dorema ammoniacum and Rheum ribes in ranges of Baghedar region, Information of vegetation were harvested with systematic-random method in the form of 40 plots and during 4 transects. After drilling soil profiles in beginning and end of each transect and samples of 0-10 and 110-80 cm, the parameters pH, EC, CaCo3, organic carbon, CaSo4, Co3, Hco3, Cl, So4, Ca, Mg, Na, Fe, Cu and soil classification grain distribution was determined in the laboratory. After Collection of data for Analysis, it was used Principal components analysis method. The results of analysis between soil variables and vegetation show that soil texture, CaCo3, EC, OC, CA, Mg, Cl and Na had more impact on distribution of vegetation types and Dorema ammoniacum and Rheum ribes.
