دراسة تحليلية للعلاقة بين قطر أشجار الصنوبر البروتي Ten Pinus brutia و حجمها في مواقع من محافظة دمشق و ريفها

الملخص EN

This research aimed to determine the relationship between diameter and volume of Pinus trees afforested in Damascus province and its countryside.

Breast height diameter (130 cm) and height of tree were measured for more than 500 Pinus brutia Ten.

trees.

The relationship between diameter and volume was studied, and a model of diameter and volume was developed as a polynomial model represented as follow: V = 0.001DBH2 - 0.0152 DBH + 0.0798 Results revealed a strong and significant correlation (r= 0.93, p<0.01) between the diameter and the volume of trees, with a high coefficient of determination (R2 =0.87).
