Hacim tahmini, büyüme ve hasılat modellerinin en önemli parçalarından birisidir. Bu nedenle, ağaç hacimlerinin gereceğe yakın bir şekilde tahmini için güvenilir metotlara ihtiyaç vardır. Ancak halen kullanılmakta olan ağaç hacim tabloları ve gövde çapı modelleri gibi tahmin yöntemlerinin herhangi bir alanda kullanımadan önce uygunluğunun test edilmesi gerekmektedir. Bu, masraflı ve zaman gerektiren bir işlemdir. Bu çalışmanın amacı; ağaç hacim tablosu ve gövde çapı modeli ile elde edilen hacimleri, daha genel metotlar olan Centroid, Paracone ve Hossfeld yöntemleri ile elde edilen hacimlerle karşılaştırmak ve hangi metodun daha doğru sonuçlar verdiğini ortaya koymaktır. Bu amaçla, 292 adet kızılçam ağacı kesilmiş, bu ağaçlar üzerinde 1 m aralıkla çaplar ölçülmüş ve bu çaplar yardımıyla örnek ağaçların gerçek hacmi olarak kabul edilecek değerler hesaplanmıştır. İkinci aşamada, ağaç hacim tablosu, gövde çapı modeli, Centroid, Paracone ve Hossfeld yöntemleri ile ağaçların hacmi tahmin edilmiş ve gerçek hacim değerleri ile karşılaştırılmıştır. Sonuç olarak, Paracone, Centroid ve Hossfeld metotlarının yanlı sonuçlar üretmesine karşın, daha düşük tolerans aralığı (TA) ve hata kareler ortalaması (MSE) değerleri ortaya koyması nedeniyle hacim tablosu ve gövde çapı modeline tercih edilebileceği görülmüştür. Ancak, envanterin önemi ve maliyeti gibi kriterler dikkate alındığında, ağaç hacim tahminleri için hangi metodun kullanılacağına karar verecek olan uygulayıcıdır.

Volume estimation is one of the most components
of growth and yield models. There is a need to reliable and accurate methods to
accurately determine the volume of trees. Current methods include the use of
volume tables or taper models which should be tested for applicability before
use in a stand. This can be costly and time consuming. The purpose of this
paper was to compare the estimates made using accepted volume table and taper
model and the more generic methods as Centroid, Paracone, and Hossfeld and
determine which gives the best results. For this aim, 292 brutian pine trees
were harvested, diameter measurements were taken every 1 m and then these
measurements were used to calculate the true volumes of each tree. The
appropriate tree volume tables and taper model for brutian pine trees and
Centroid, Paracone, and Hossfeld methods were used to estimate the tree volumes
and these estimates were compared with true volumes. Overall, the Paracone,
Centroid, and Hossfeld methods performed well in comparison with the other
techniques but results generally were significantly biased, although these
biases were small. Precision was better for the Paracone and Centroid methods
than the other methods.  In determining
the method to apply for estimating the volume of the trees in filed, the
forester will have to decide whether which method to use.
