Akdeniz Bölgesi’nin geçiş zonunda yetişme ortamı sınıflandırması için bağımlı değişkenin analitik olarak belirlenmesi

Orman yetişme ortamı sınıflandırması ve haritalamasında, bitki türlerinin yayılışı ile çevre faktörleri arasındaki ilişkilerin belirlenmesi önemlidir. Bu sebepten, bitki türleri itibariyle örnek alan grupları ve bu grupların gösterge bitkileri orman yetişme ortamı sınıflandırması için bağımlı değişken anlamı taşımaktadır. Bitki türlerinin yayılışı itibariyle örnek alanların gruplandırmasında kullanılan birçok analitik yöntem vardır. Bunlardan biride normal birliktelik analizidir. Normal birliktelik analizi bitki türlerine göre örnek alanların hiyerarşik olarak gruplandırılmasını sağlayan nonparametrik bir yöntemdir. Bu araştırma, Akdeniz bölgesi’nin geçiş zonunda bulunan Gencek Yetişme ortamı Yöreler Grubunda, 55 örnek alandan toplanan verilerle gerçekleştirilmiştir. Uygulanan normal birliktelik analizi sonucu 6 grup elde edilmiştir. Grupları, Pyrus elaegnifolia, Quercus trojana, Euphorbia ssp., Acer platonoides ve Juniperus oxycedrus türleri ayırmıştır. Böylece, Gencek Yetişme Ortamı Yöreler Grubunda, bitki türlerini dağılımında rol oynayan faktörlerin belirlenmesini sağlayacak bağımlı değişken elde edilmiştir. Nihayet, bu bağımlı değişkenin çevresel faktörler ile ilişkilendirilmesi ile yetişme ortamı sınıflandırmasında önem arz eden yetişme ortamı faktörleri belirlenebilecektir.

Determination of dependent variable by quantitative analysis for the classification on forest sites in the translation zone of Mediterrenian Region

Determination of the relation between the distribution of plant species and environmental factors is important in terms of classification and mapping on forest sites. Hence, the groups belonging to sample plots according to plant species and indicator species of this groups mean independence variable for forest site classification. There are many statistical methots in order to classify the sample plots according to plant species. One of them is normal association analysis. Normal association analysis is a nonparametric methot which supply to divide hierarchical to the quatrats according to plant species. In this study, it has been obtained 6 groups in accordance with normal association analysis for 55 quatrats in Gencek Site Section Group belonging to translatin zone of Mediterrean region. Pyrus elaegnifolia, Quercus trojana, Euphorbia ssp., Acer platonoides and Juniperus oxycedrus has been divided to the quatrats into groups. Thus, it has been obtained dependent classification variable to supply to determinate to the factors effecting on distribution of plant species. Finally, significant environmental factors can be determineted for classification on forest sites in determining the relationships between independent variable and environmental factors
