The Effect of Ecological Factors on Vegetation in Hamedan Alvand Region (Iran)
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 5
Abstract
The objective of this research was to study the relationships between environmental factors and vegetation in order to find the most effective factors in the distribution of plant species in Hamedan Alvand region. Sampling of soil and Floristic composition were performed with Ecophytosociology method with emphasis on physiognomic-floristic-ecologic criteria. The data analysis was performed by using Anaphyto Software in F.C.A. and A.H.C. Method. In this survey, 143 special stations (releve) were studied. Floristic and ecological data were estimated quantitatively within each releve. Results showed that the effective ecological factors of the region were classified as the principal, determinant and differential ecological factors. Obtained data showed that the elevation factor of the region was the principal ecological factor, the factors of elevation, slope as well as the aspect is the determinant ecological factors and the factors of pH, EC and texture of soil were effective as the differential ecological factors.
