Abstract

Arazi kullanımı değişimi, bölgesel, ekonomik ve sosyal gelişiminde hayati rol oynamaktadır.
Bu çalışmanın amacı, Peyzaj Ekolojisi ilkesine dayalı CBS teknikleri kullanarak Edremit
Körfezi’nin kuzey sahil bölgesinde peyzaj paterninin ve arazi örtüsünün zamansal ve
mekânsal değişimini nicel olarak ortaya koymak ve açıklamaktır. Bu çalışmada üç farklı
Landsat TM ve ETM+ (1987, 2000 ve 2010) uydu görüntüsü kullanılmıştır. Mekânsal desen
ve mekânsal heterojenite peyzaj metrikleri hesaplanarak analiz edilmiştir. Hesaplamalar
sırasında hem standart hem de hareketli pencere (moving window) analizleri kullanılmıştır.
Peyzaj değişimi ile ilgili olarak, peyzaj yapısından mekânsal dağılım ve ilişkinin
yönü tartışılmıştır. 1987-2010 döneminde, özellikle dağlarda ormanlarda artış ve sahil
bölgelerinde yapay alanlarda bir artış fakat zeytinlik ve meyvelerde bir azalış belirlenmiştir.
Yoğun ekili tarım alanlarında da belirgin bir azalma tespit edilmiştir. Zeytin ağaçlarının
(Olea europaea subsp. europaea) baskın olduğu zeytinlik-meyvelik arazileri inşaa
edilmiş arazilere dönüştüren kentleşme süreçleri, son yirmi yılda, bölgede peyzaj deseninin
zamansal ve mekânsal değişmesine yol açan en önemli etkendir. Sonuçlar peyzaj
kompozisyonu ve biçiminin arazi örtüsü değişiminin açıklanmasında önemli olduğunu ortaya
koymuştur. Bölgede artan koruma çabası sadece orman alanlarını korumak için değil
geleneksel tarım uygulamalarını içeren zeytinliklerin korunması için de yapılmalıdır

Spatiotemporal Change of Land Cover and Landscape Pattern in the North Coastal Region of Edremit Gulf

Abstract

Land use change plays vital roles in regional, economic and social development.
The objective of this study is to explore and explain quantitatively the spatiotemporal
changes of land cover and landscape pattern in the North Coastal Region of the
Gulf Edremit, in Egean Sea with GIS Based on the principle of landscape ecology.
In this study, three different Landsat TM and ETM+ images (1987, 2000 and 2010)
were used. The spatial pattern and spatial heterogeneity are analyzed by employing
and computing landscape metric variables. Both standard and moving window analyses
were carried out on the datasets. From landscape structure, spatial distribution
and relationship aspects discussed about the landscape changes. We measured an
increase in forests and especially in mountains, an increase in artificial areas, especially
in coastal zones, but a decrease in orchlands in coastal zones during 1987–
2010. Extensively cultivated areas showed a marked decrease. Urbanization processes
developed to transfer orchland dominanted with olive trees (Olea europaea
subsp. Europaea) into buildup land is the most important force leading to the spatiotemporal
change of landscape pattern in the area, in the last two decades. Results
indicate that landscape composition and configuration were important in explaining
land cover change. We suggest that an increasing conservation effort should be made
to protect not only for the forest areas but also the traditional Olive cultuvitation including
agricultural practices.
