Brutian pine is one of the important commercial species for forest products industry of Turkey. In this study, compatible segmented taper and volume models were developed for Brutian pine stands in Burdur Region of Turkey. Max and Burkhart (1976) and Parresol et al. (1987) segmented taper and volume functions were used in this study. The proposed models generally performed better for whole tree and different sections of tree bole for taper and stem volume. The equation proposed by Max and Burkhart (1976) performed significantly better than Parresol et al. (1987) equation for this tree species. Average diameter prediction error was less than 2.3 cm and average volume error was less than 0.008 m3 in different points on bole. Model estimates compared, using an independent dataset, well to existing tree volume table and tree volume equation prediction errors for Brutian pine were found to be larger than those for the proposed volume models.

Burdur Yöresi kızılçam meşcereleri için uyumlu gövde çapı ve gövde hacim denklemlerinin geliştirilmesi

Öz

Kızılçam, ülkemizde orman ürünleri sanayisi için en önemli ticari ağaç türlerinden biridir. Bu çalışmada, Burdur yöresi kızılçam meşcereleri için uyumlu gövde çapı ve gövde hacim modelleri geliştirilmiştir. Bu amaçla, Max ve Burkhart (1976) ve Parresol vd. (1987) tarafından geliştirilen parçalı gövde çapı ve gövde hacim modelleri kullanılmıştır. Önerilen modeller, gövde çapı ve gövde hacim tahminlerinde, genel olarak tüm ağaç gövdesi ve gövdenin farklı bölümleri için güvenilir sonuçlar vermiştir. Ancak, en başarılı sonuçlar Max ve Burkhart (1976) tarafından geliştirilen parçalı gövde çapı ve hacim modeli ile elde edilmiştir. Bu model ile gövde üzerinde değişik noktalarda yapılan çap tahminlerinde ortalama hata 2.3 cm'den ve hacim tahminlerinde 0.008 m3'den daha az bulunmuştur. Önerilen model, bağımsız veri seti kullanılarak, yöresel tek girişli ağaç hacim tablosu ile de karşılaştırılmış, ağaç hacim tablosu kullanılarak elde edilen hacim değerlerinin daha yüksek hata miktarına sahip oldukları görülmüştür.
