First, the land units were obtained based on topographic map and overlaying of slope, altitude and lithology map. Sampling was conducted in each land unit by systematic method after field surveying. Size and the number of plots were obtained on the basis of minimal area and statistical method respectively. Type of species for sampling was determined by Twinspan analysis. Then vegetation percentage and frequency were recorded based on Krijina scale in each plot. Soil and plants were sampled in each plot. In addition, soil physico-chemical characteristics and nutritional elements were calculated by ICP in lab. Data analysis was conducted by the analysis of variance and means comparision in SAS 9.1 software. Then, the relation between soil elements and species was determined by using DCA and CCA analysis in Canoco for Win4.0 software. The results showed that the nutritional elements in plants were more than the soil. The amount of micro elements in under growth organs was more than aerial parts, but in the macro elements it was inverted. Morover, the relationship between the nutritional elements of different species and soil absorbable elements was not constant it was dependent on site conditions such as moisture, pH, lime, organic matter, texture, and other species and soil elements that were affected by nutrition mobility and their absorbtion rate.
