Abstract
The vegetative cover well-establishment subject to matrix governance is inter alia the most important environmental factors. Gaining an insight over the entire factors and comprehending their interrelationships with the quantitative attributes of the vegetative cover can be done through classical statistical methods. But, the existence of some relationships in the hidden structure of the environmental factors render classical statistical methods inefficient and unable to accurately demonstrate these collateral relationships. Therefore, the use of gradient analysis can precisely reveal the hidden structure and then the authentic ecological grouping of the plant species can follows. Based thereon, the most important factors associated with the soil were identified to determine the ecological plant groups inside and outside a protected area both of which featuring similar topographical and climatic conditions. In each area, the measurements of canopy percentage as well as the density and frequency of the plant species based on random-systematic sampling method via placement of 5 transects, 50 meters in length, and placement of 10 quadrats, 1 square meter in area, based on antenna method were carried out so as to better exploit the appearances of the pasture surface. Moreover, the soil samples were taken according to the boundary-layer separation horizons and the type of the extant plants considering the active rooting region from two depth ranges of 0-10 cm and 10-50 cm in a completely systematic manner of the beginning, middle and ending sections of every transect. The regression analysis results indicated that, out of the 6 ecological plant groups from both of the studied areas, there is a relationship between Amygdalus lycioides, Acantholium festuacemum, Artemisia sieberi and stipa barbata and the twelvefold soil variable based on classical statistical methods but no particular behavior was evidenced in the classical statistical methods regarding the two species of Convolvulus acanthocaladus and Ebenus stellata. But, the utilization of PCA and CCA methods and drawing of raster graphs and making of classifications finally led to the identification of the soil factors influencing the establishment of these two species in both inside and outside the conserved area.
