Abstract :

Background and Objective: Afforestation stand of Ghapan region (with 232 ha-1 area) was selected for investigation of quantitative and qualitative characteristics of Pinus brutia ten. Method: Three altitude classes (200-400, 400-600 and 600-800m) were classified and  number of 30 sample plots (with 400m2 area) were selected by using of random – systematically method in every classes. Some of quantitative and qualitative characteristics were recorded in every sample plots. Also, three soil profiles (A and B horizons) were excavated in every three altitude classes for investigation of soil properties. Findings: Results of this research showed that mean D.B.H and height was similar to normal distribution. Volume of high class (600-800m) was estimated more than the other two classes. Qualitative characteristics showed that plummet of stem, stem without branch, fresh of crown were climbing as crown symmetry and stem curvature were reducing with increase of altitude. Multi branch and stem healthy don’t show regular changes in relation to altitude changes. Soil studies showed no significant different in relation with altitude changes. Discussion and Counclusion: The final result shows that pinus brutia ten stands with the best quality and quantity and it is visible in high altitudes.
