Bu çalışmanın amacı, Türkmen Dağı
(Eskişehir, Kütahya) Bölgesi sarıçam (Pinus sylvestris L. subsp. hamata
(Steven) Fomin.) ormanlarında ağaç bileşenlerine ait karbon yoğunlukları ile
bazı meşcere ve yetişme ortamı özellikleri arasındaki ilişkileri belirlemektir.
Örneklemeler farklı yetişme ortamı özelliklerine sahip 58 alanda yapılmıştır.
Elde edilen veriler varyans ve korelasyon analizleri ile değerlendirilmiştir.
Altı ağaç bileşeninin karbon yoğunlukları arasında istatistik bakımdan önemli
farklılıklar bulunmuştur (p<0,001). Karbon yoğunluğu en düşük kökte
(%50,94), en yüksek ise kabukta (%54,75) bulunmuştur. Sarıçam ormanları için
ağırlıklı karbon oranı %52,37 olarak hesaplanmıştır. Ağaç bileşenlerine ait
karbon yoğunlukları ile bazı meşcere ve yetişme ortamı özellikleri arasında
önemli ilişkiler tespit edilmiştir. Bonitet endeksi ve yükselti ile ağaç
bileşenleri karbon oranları arasında negatif ilişki bulunmuştur. Ancak yükselti
ile bir ve iki yaşlı ibre karbon oranları arasındaki ilişki daha güçlü (p<0,01)
ortaya çıkmıştır. Ayrıca yamaç konumu iki ve üç yaşlı ibre karbon oranı ile
pozitif ilişki gösterirken kabuk karbon oranı ile negatif ilişki göstermiştir.
Elde edilen karbon oranları, sarıçam ormanlarında gerek ağaçlarda gerekse
ağaçların farklı bileşenlerinde depolanan karbon stoğunun hesaplanmasında
kullanılabilir.

Determination of carbon concentration of tree components for Scotch pine forests in Türkmen Mountain (Eskişehir, Kütahya) Region

Abstract

DOI: 10.26650/ forestist.2018.330657

The purpose of this study was to
investigate the relationship between carbon concentration of different tree
components and some ecological factors for Scotch pine (Pinus sylvestris L.
subsp. hamata (Steven) Fomin.) in Türkmen Mountain Region. Data were collected
from 58 ecologically different sample plots and were evaluated using ANOVA and
correlation analysis. Carbon concentration varied significantly within five
tree components (p<0.001), with the values ranging from 50.94% for root to
54.75% for bark. We also calculated the weighted carbon concentration as 52.37%
for Scotch pine forests. Some significant relationships were found between the
carbon concentration of tree components and some ecological factors and stand
parameters. Site index and elevation negatively correlated with tree component
carbon concentration. However, elevation strongly correlated with 1- and
2-year-old needle carbon concentration (p<0.01). We also found that slope
position positively correlated with 2- and 3-year-old needles but negatively
correlated with bark in terms of carbon concentration. The carbon
concentrations that we calculated in this study can be used for calculating the
carbon content of either whole tree or any tree component in Scotch pine
forests.
