Conclusion: As a result of this research, depending on urban development, the transformation of agricultural areas, open areas, semi-natural areas, salty marshes into impermeable areas such as settlement, industry, transportation, fragmentation, isolation of habitat patches and loss of open area and natural vegetation have changed the structure and function of the landscape. .

Abstract

Objective: The aim of this study is to evaluate and determine landscape structure depending on land use/land cover (LULC) changes between 1990 and 2009 in the central districts of Izmir province between 1990 and 2009 using landscape metrics. Material and Methods: In this study, land use/land cover maps for study area were derived from two different time periods Landsat 5 TM (Thematic Mapper) acquared in August 07, 1990 and in July 26, 2009 using pixel based supervised classification method. Nine landscape metrics were calculated to evaluate change in landscape structure according to land use/land cover classes. Results: In the study area, when the urban landscape structure change is examined between 1990 and 2009, it was observed that the average patch size and weighted average patch size of artificial surfaces are increased. When these values evaluated together with PROX_AM, ENN_AM, MESH and IJI values, shows that artificial surfaces expand and grow in the landscape and patches are located closer to each other. Depending on this expansion, there has been a significant decrease in agricultural areas, semi-natural areas and open areas. Conclusion: As a result of this research, depending on urban development, the transformation of agricultural areas, open areas, semi-natural areas, salty marshes into impermeable areas such as settlement, industry, transportation, fragmentation, isolation of habitat patches and loss of open area and natural vegetation have changed the structure and function of the landscape. .

Özet

Amaç: İzmir ilinde hızlı nüfus artışı ve yoğun kentleşme hareketinin görüldüğü merkez ilçelerinde, 1990 ve 2009 yılları arasındaki alan kullanım/arazi örtüsü (AKAÖ) değişimlerinin peyzaj yapısına etkilerinin peyzaj metrikleri ile analiz edilerek değerlendirilmesidir. Materyal ve Metot: Çalışmada, araştırma alanındaki alan kullanım/arazi örtüsü haritaları 07.08.1990 ve 26.07.2009 yıllarına ait Landsat 5 TM uydu görüntülerine piksel tabanlı kontrollü sınıflandırma yöntemi uygulanarak elde edilmiştir. Peyzaj yapısındaki değişimin alan kullanım/arazi örtüsü sınıflarına göre değerlendirilmesinde 9 peyzaj metriği hesaplanmıştır. Bulgular: Çalışma alanında, 1990 ve 2009 yılları arasında, kentsel peyzaj yapısındaki değişim incelendiğinde, yapay yüzeylerin ortalama yama büyüklüğü ve ağırlıklı ortalama yama büyüklüğü değeri artış göstermiştir. Bu artış PROX_AM, ENN_AM, MESH ve IJI değerleri ile birlikte değerlendirildiğinde, yapay yüzeylerin peyzaj içinde genişleyerek büyüdüğü ve yamaların birbirine daha yakın konumlandığını göstermektedir. Bu genişlemeye bağlı olarak tarım alanları, yarı doğal alanlar ve açık alanlarda belirgin azalmalar olmuştur. Sonuç: Araştırma sonucunda, kentsel gelişmeye bağlı olarak tarımsal alanların, açık alanların, yarı doğal alanların ve tuzlu bataklıkların yerleşim, sanayi, ulaşım gibi geçirimsiz alanlara dönüştürülmesinin, parçalanma, habitat yamalarının izolasyonu, açık alan ve doğal bitki örtüsü kaybı gibi çeşitli süreçlerle peyzajın yapısını değiştirdiği saptanmıştır.
