Abstract

Agropyron intermediumspecies has good quality and the preference value that is important in soil conservation and forage production for livestock. Ecological niche factor analysis (ENFA) is a multivariate approach to the study of the geographical distribution of species based on environmental factors and present only. For modeling, vegetation data in addition to site condition information including topography, climate, geology and soil were prepared. Within each sampling unit, three parallel transects with 150m length, each containing 15 quadrats were established. Sampling method was randomized-systematic method. Quadrats size determined for each vegetation type using the minimal area and their number were determined according to vegetation variation. Soil samples were taken from 0-30cm in along of each transects and soil properties were measured in the laboratory. For data analysis and prepare environmental variables maps geostatistical methods. Biomapper4 Software was used for habitat SUITABILITY MAP for A. intermedium. According to the results of the model habitat suitability for A. intermedium species is more in the height evolution (2550m), slop (45%), organic matter and lower lime and clay-loam soil in site study. Accuracy model is calculated 84% using continue Boyce index. Kappa coefficient obtained by matching the prediction map with ground truth (kappa=0.76) to verify the accuracy of the model results. In addition to, the results of this study indicated that this species has a moderate tolerance to the environmental variables, Also has lower specialized that can tolerate life in the range of environmental variables in the study area.
