Abstract :

Goroj species (Gymnocarpus decander) one of the most important species in the meadows of the Hormozgan province, which ranges widely from province to emerge as one of the element type is a mechanism of protection soil and forage production for livestock pastures play an important role in the province. lack of adequate rainfalls, drought, heavy grazing and uncontrolled, the additional pressure on the plant species and the degradation and destruction of these species can be in different areas the province was well observed. In order to check the status of species Goroj Climate parameters include temperature, precipitation, humidity, evaporation, wind phenomenon, sundial and the plant parameters such as density and percent cover was assessed and analyzed using SPSS statistical software. Investigation of the degree of correlation between climatic and plant parameters showed a significant correlation. So, by using of multiple regressions, the decreases in independent climatic parameters into the parameters which had more effect on the plant dependent parameters were done. Altogether, it was found that the climatic element of the average of annual maximum temperature with 34.5 percent of the dependent variable changes has the greatest impact on Goroj species distribution.
