Abstract: (1924 Views)

Ecophysiography is the study of the relationship between physiography and the ecosystem, which forms the basis for planning processes to study the characteristics of terrestrial systems. With the current state of ecosystems and the increase in natural disasters, the assessment of ecophysiographic features is crucial for solving ecosystem problems and providing better ecosystem services. This study aimed to analyze the relationship between the quantitative characteristics of trees and physiographic factors in slope aspects and elevation ranges in oak and hornbeam-dominated stands in Arasbaran. Data was collected from six square sample plots with dimensions of 100 m ×100 m in three altitude ranges and two slope aspects. The study found that the elevation and slope aspects did not significantly affect the diameter and basal area of trees, but had a significant impact on tree height, average canopy diameter, and canopy area. The northwest slope was more homogeneous in all studied features, while the northeast slope showed more changes. Trees from the valley to the peak had a significant increase in height and canopy. The study also revealed a significant correlation between the diameter and basal area, and the canopy area and average canopy diameter. The study showed that ecophysiographic factors affected some quantitative characteristics of oak-hornbeam stands in Arasbaran, and the trees had significant changes due to the nature of the tendency to adapt to the environment. The study also demonstrated the interaction effects of aspects and elevation ranges on stand characteristics. Canopy area and average canopy diameter had a significant difference, while other characteristics did not show any significant difference.
