Abstract

In this study, it is proposed to determine the relationship between the diameter at stump height (d0.3) and diameter breast height (d1.30) for Scotch Pine (Pinus sylvestris (L.)) in West Black Sea Region including Kastamonu, Bolu and Ankara forest regional offices. For this purpose, 101 temporary sample plots were obtained and 1111 tree measurements for stump height (d0.3) and diameter breast height (d1.3) were carried out. The different regression models were selected and compared to some success criteria. The most successful results were achieved with the parabolic equation. This regression model explains 96.7 % of the variability in diameter breast height (d1.3). It is concluded that the model predicting the diameter at breast height from diameter at stump height (d0.3) can be used confidentially.

Özet

Bu çalışmada, Batı Karadeniz Bölgesinde Ankara, Kastamonu ve Bolu Orman Bölge Müdürlükleri sınırları içinde yayılış gösteren sarıçam meşcerelerinin dip kütük çapı-göğüs çapı ilişkisinin belirlenmesi ve modellenmesi amaçlanmıştır. Bu amaçla, çalışma kapsamındaki meşcerelerden 101 adet örnek alan alınmış ve 1111 adet örnek ağaçta dip kütük çapı ve göğüs çapı ölçümleri yapılmıştır. Elde edilen bu verilere bağlı olarak, çeşitli regresyon modelleri denenmiş ve bu modellerden başarı ölçütlerine göre en iyi sonuç parabolik denklem ile elde edilmiştir. Göğüs çapındaki değişkenliğin %96.7’sini açıklayan bu model, dip kütük çapı kullanılarak göğüs çapı tahmininde güvenle kullanılabileceği sonucuna varılmıştır.
