Göğüs çapı, kolay ölçülebilir olması ve
diğer ağaç değişkenleriyle yüksek korelasyona sahip olmasından dolayı, tek ağaç
veya meşcere parametrelerinin birçoğunun hesaplanmasında bağımsız bir değişken
olarak kullanılmaktadır. Ancak ormanlık alandan ayrılmış olan ağaç hakkında
bilgi sahibi olabilmek için göğüs çapı büyüklüğünü tahmin etmek gerekmektedir.
Bu çalışmada, Doğu Ladini (L), Sarıçam (Çs) ve Doğu Karadeniz Göknarı (G)
karışık meşcerelerinde göğüs çapı-kütük çapı ilişkisi araştırılmıştır. Bu
amaçla Artvin’de tam kapalı olan LÇsG ve ÇsLG meşcerelerinden alınan 23 farklı
örnek alandan kesilmiş olan 206 ağaç (69 adet L, 69 adet Çs ve  68 adet G) verisi kullanılmıştır. Yapılan
istatistiksel analizlere göre, göğüs çapındaki değişkenliği açıklayan en iyi
modeller Ladin’de power, Sarıçamda kuadratik ve Göknarda ise doğrusal modeller
olmuştur. Bu modellerin üçlü karışık meşcerlerde göğüs çapı değişkenliğini
açıklama oranları Ladin için %95,2, Sarıçam için %96,5 ve Göknar için de %96,4
ve bu modellerin hataları da sırasıyla 1.850, 1.598 ve 1.643 şeklinde
bulunmuştur. Sonuç olarak, göğüs çapını tahmin etmede belli başarı seviyesinde
olan bu modeller, Artvin’deki tam kapalı üçlü karışık meşcerelerde
uygulayıcılar tarafından kullanılabilir olarak bulunmuştur.

Estimating diameter at breast height (DBH) from diameter at stump height (DST) in triple mixed stands in the region of Artvin in Turkey

Abstract

DOI: 10.26650/forestist.2019.18003

Diameter at breast height is used as an
independent variable in the calculation of most tree or stand parameters
because it can be measured easily and has high correlation with tree variables.
But, it is necessary to estimate the size of the DBH of the tree concerned to
have knowledge of the tree which has been separated from the area. In this
study, DST-DBH relationships were investigated on stands where Oriental Spruce
(So), Scots Pine (Ps) and Eastern Black sea Fir (Fb) were mixed. For this
purpose, 206 trees (69 So, 69 Ps and 68 Fb) were used which were cut from 23
different sample areas taken in fully closed SoPsFb and PsSoFb stands in
Artvin. According to the statistics analysis; models that best explain the
variability of the DBH are power for spruce, quadratic for pine and linear
models for fir. These models can explain the variance of DBH in triple mixed
stands by 95.2% for spruce, 96.5% for pine and 96.4% for fir, and standard
errors of models are 1.850, 1.598 and 1.643 respectively. As a result, these
models, which at a certain height of success in predicting DBH, can be used by
practitioners at fully closed triple mixed stands in Artvin.
