Leaf area index is one of the most important factors in presenting the basic structural characteristics of forest ecosystems. Because, leaf area index can reveal the change of many biological and physical processes in the canopy. So, determination of the leaf area index is very important in forestry. In calculation of the leaf area index many direct and indirect methods are used. In this study direct method was used in calculation. For this purpose, measurements were made in 180 shoots taken from a total of 45 trees from different stands at the same altitude, aspect and have the same slope gradient and approximately same canopy closure (0.9-1.0). Obtained results showed that leaf area index was higher in the samples taken from North aspect ( (σ = 0,93))  then South (  (σ = 0,971)). Obtained results indicated that silvicultural treatments at different intensity should be carried out even if the stands were in the same stand structure.

Yaprak alan indeksi (YAİ), orman ekosistemlerinin temel yapısal karakterlerinin ortaya konmasında önemli faktörlerin başında gelmektedir. Çünkü YAİ meşcerenin tepe çatısında oluşan birçok biyolojik ve fiziksel sürecin değişimini ortaya koyabilmektedir. Bu bağlamda, YAİ değerlerinin belirlenmesi ormancılık açısından önem taşımaktadır. YAİ’nin hesaplanmasında doğrudan ve dolaylı birçok yöntem kullanılmaktadır. Bu çalışmada doğrudan belirlenme yöntemi kullanılmıştır. Bunun için farklı bakılarda, aynı yükseklik, aynı eğim ve yaklaşık aynı kapalılıkta (0,9-1,0) meşcerelerden toplam 45 adet ağaçtan alınan 180 sürgünde ölçümler yapılmıştır. Buna göre kuzey ve güney olarak farklı bakılardan alınan ağaçlarda yapılan YAİ değerleri farklı (güney bakılardaki ağaçlarda  (σ = 0,971) ve kuzey bakılardaki ağaçlarda  (σ = 0,93)) bulunmuştur. YAİ değerleri kuzey bakıdan alınan örneklerde daha yüksek çıkmıştır. Bu sonuca göre, silvikültürel müdahalelerin yapılacağı meşcerelerden aynı meşcere yapısında olsa dahi farklı şiddette uygulamaların yapılması gerektiği önerilmiştir.
