Abstract

Çalışmanın temel amacı, farklı yaş sınıfı dağılımlarına sahip kızılçam ormanlarının odun üretimi ve karbon birikimi fonksiyonlarını birlikte ele alan optimizasyon modellerinin geliştirilmesidir. Bu kapsamda öncelikle, farklı yaş sınıfı dağılımlarına sahip hipotetik kızılçam ormanları oluşturulmuştur. Daha sonra, odun üretimi ve karbon birikimi değerleri sayısallaştırılarak, uzun dönem için çok amaçlı orman amenajmanı planlama modellemesi yapılmıştır. Planlama modellerine karbon birikimi fonksiyonun dahil edilmesinin, planlama süresi sonunda ilgili ormandan elde edilecek toplam net bugünkü değer üzerine olan katkıları ortaya konulmuştur. Çok amaçlı orman amenajmanı planlama problemi, doğrusal programlama tekniğine dayalı olarak modellenmiştir. Planlama süresi 100 yıl ve planlama periyodu 10 yıl olarak alınmıştır. Farklı özelliklere sahip planlama senaryolarının çözümü sonucunda, ormanların sunmuş olduğu iki önemli fonksiyon olan odun üretimi ve karbon birikimi üzerinde, aktüel orman kuruluşlarının önemli etkiye sahip olduğu görülmüştür.

Optimization of wood production and carbon sequestration functions in Turkish red pine forests with different age-classes distribution with linear programming technique

Abstract

The main purpose of the study is to develop optimization models that deal with the wood production and carbon sequestration functions of Turkish red pine forests with different age-classes distribution. In this context, first of all, hypothetical red pine forests with different forest structures created. Then, wood production and carbon sequestration values were quantified and multi-purpose forest management planning modeling for the long term was made. The contribution of the inclusion of the carbon sequestration value to the planning models on the total net present value to be obtained from the relevant forest at the end of the planning period has been revealed. The multi-purpose forest management planning problem is modeled based on the linear programming technique. The planning horizon is taken as 100 years and the planning period as 10 years. As a result of the solution of planning scenarios with different characteristics, it has been seen that the current forest ecosystem structures have a significant effect on wood production and carbon sequestration which are two important values provided by forests.
