Zygophyllumatriplicoides is one of the most important species rang lands of country. A desert shrub that can tolerate long term droughts. This feather is going to studied climate specification of Zygophyllumatriplicoides habitats in Isfahan province. So the numbers of 68 climate variables that have more important is aspect of the ecological conditions selected and the method of factor analysis, factors that influence the distribution of species studied. Using factor analysis, four factor, the cooling temperature, precipitation, cloudy and wind were determined. It is allocated 34.45, 29.43, 11.79 and 9.06 the percent of variance variable sequential, that repeat 84.74 percent of changes totally. Average of factor scores and climate variables are determined in three types of Zygophyllumatriplicoides as dominant specie, Zygophyllum specie as following specie and zones of Zygophyllum free, and finally the impact of factors and climate primary variables on Zygophyllumatriplicoides types are determinate. Besides climate factors, effect of height from sea level in distribution of specie is analyzed. The results show that temperature factor was most important of effective climate factor on specie distribution in Isfahan province and then precipitation factor affects distribution of specie. Also it cannot ignore the effect of height from sea level on Zygophyllum types of analyze.
