Bölgelerin
iklimsel özelliklerinin, ağaç türlerinin çeşitliliğini ve yapısal özelliklerini
etkilemesine karşın bitki örtüsü yapısı da mikro iklim üzerinde etkili
olmaktadır. Bu çalışmada, bu bilgiye dayanarak, Şile’nin Mercanköşk Orman
İşletme Şefliği sınırı içerisinde kalan ve homojen yapı sergileyen kayın ve
meşe meşcereleri ele alınarak yüzey sıcaklığı farklılıkları ortaya konulmaya
çalışılmıştır

2011 Landsat TM-5 ve 2013, 2014 ve 2015 yıllarına ait Landsat 8 - ETM
termal görüntüleri üzerinden elde edilen yüzey sıcaklığı bilgileri, meşcere verisi
ile ilişkilendirilerek istatistiksel olarak karşılaştırılmıştır.
Elde edilen sonuçlara göre, iki ağaç türüne ait homojen meşcere alanları
arasında 2.4°C’ye varan yüzey sıcaklığı farklarının oluştuğu tespit edilmiştir.
Bölgesel özelliklerin hemen hemen benzer olduğu
şeflik sınırları içerisinde oluşan bu sıcaklık farkı, iklimsel açıdan gözardı
edilemeyecek bir etki yaratmaktadır. Özellikle küresel ısınmayla mücadele
kapsamında yapılan hazırlık çalışmalarında, bu bilgilerin bölgesel envanter
olarak kullanılmasının, elde edilecek başarı üzerinde etkili olacağı
düşünülmektedir.

Investigation of Surface Temperature Differentiation of Fagus and Quercus Stands by Using Landsat Images

Öz

While
climatic features of regions affect the variety of tree species and their
structures, the vegetation structures of the regions are effective on micro
climate. In this study, thermal differentiations in the  Fagus and Quercus stands which are homogenous in structure and are found within the
boundaries of Mercanköşk Forest
Sub-District Directorate in Şile are presented.

The surface temperature data which is obtained by Landsat TM-5 and Landsat
8 - ETM thermal images during 2011, 2013, 2014 and 2015 is compared
statistically in relation to data obtained from the stand. According
to the results obtained, it has been found out that there is a difference of
surface temperature up to 2.4°C among tree types. This surface temperature difference which is within the boundaries of forest
sub-district directorate having similar regional features has an
undeniable effect in terms of climate. It has been thought that using this
information as a regional inventory in the preparatory studies within the scope
of tackling with global warming will be effective on the success to be
achieved.
