Abstract

The aim of this research was to study the relationships between presence of PLANT SPECIES and ENVIRONMENTAL FACTORS in Poshtkoh rangelands of Yazd province. After delimitation of the study area, sampling was performed using randomized-systematic method. Accordingly, vegetation data including presence, density and cover percentage were determined in each plot. The topographic conditions were recorded in plot locations. Soil samples were taken at depths of 0-30 and 30-60 cm in each plot. The measured soil variables included texture, lime, saturation moisture, gypsum, acidity (pH), ECe and SAR. LOGISTIC REGRESSION technique was used to analyze the collected data. The results showed that the vegetation distribution is mainly related to soil characteristics such as EC, saturation moisture, gypsum, gravel and lime. The presence of A. sieberi has inverse relation with EC. D. ammoniacum has also negative relation with saturation moisture, gravel and lime. While, the presence of Ep.st-Zy.eu has positive relation with gypsum.
