Özet:

 As a result of the increasing demands of human beings from the past to the present, the interaction with the natural environment conditions and the anthropogenic pressure on these environments have reached different dimensions. These pressures of anthropogenic origin can also lead to changes in geomorphological conditions and elements. In this study, the changes originating from the marble quarries in Marmara Island were analyzed with the anthropogenic geomorphology approach. In the study, the temporal and spatial dimensions of the change in marble quarries were determined in five-year periods between 1975 and 2020 and from satellite images of 2022. Then, the extent of anthropogenic change was determined by analyzing the Normalized Vegetation Difference Index, Normalized Artificial Area Difference Index, and Normalized Impervious Surface Index on the satellite images between 1985 and 2022. The ground surface temperature of the island was determined from the 2022 satellite image. All the data obtained were correlated and reanalyzed, and the change data were converted into point cloud data. Then, these data were interpolated with the modified IDW method, and the anthropogenic-sourced relief change model of Marmara Island was created. In the area of marble quarries, which have expanded in the east-west direction with an increase of 2.5 in the last 47 years in the north of Marmara Island, the topography has changed by an average of 4.3 meters. It has been determined that the ground surface temperature in the marble quarries area, where the highest change size reaches 32 meters, increased by 1.2C compared to other sections.

 Geçmişten günümüze insanoğlunun artan talepleri neticesinde doğal ortam koşulları ile olan etkileşim ve bu ortamlar üzerindeki antropojenik baskı farklı boyutlara ulaşmıştır. Antropojenik kökenli meydana gelen bu baskılar jeomorfolojik süreç ve birimlerde değişimlere yol açabilmektedir. Belirtilen kapsamda bu çalışmada Marmara Adasındaki mermer ocaklarından kaynaklı değişimler antropojenik jeomorfoloji yaklaşımı ile analiz edilmiştir. Çalışmada 19752020 yılları arası beşer yıllık periyotlar halinde ve 2022 yılına ait uydu görüntülerinden mermer ocaklarındaki değişimin zamansal ve alansal boyutları tespit edilmiştir. Daha sonra 1985 ve 2022 yılları uydu görüntülerine Normalleştirilmiş Bitki Fark İndeksi, Normalleştirilmiş Yapay Alan Farkı İndeksi, Normalleştirilmiş Geçirimsiz Yüzey İndeksi analizleri yapılarak antropojenik değişimin boyutu saptanmıştır. 2022 yılı uydu görüntüsü üzerinden ise adanın yer yüzeyi sıcaklığı tespit edilmiştir. Elde edilen bütün bulgular korelasyona tabi tutulmuş ve tekrar analiz edilerek değişim verileri nokta bulutuna dönüştürülmüştür. Daha sonra bu veriler düzenlenmiş, IDW yöntemi ile enterpole edilerek Marmara Adasının antropojenik kaynaklı rölyef değişim modeli oluşturulmuştur. Marmara Adasının kuzeyinde son 47 yılda 2,5 artışla doğu-batı yönünde genişleyen mermer ocakları sahasında topoğrafya ortalama 4,3 metre değiştirilmiştir. En yüksek değişim boyutunun 32 metreye ulaştığı mermer ocakları sahasında yer yüzeyi sıcaklığının adadaki diğer arazi kullanım sahalarına göre 1,2C artış gösterdiği tespit edilmiştir.
