In this study, the urban green space distribution was determined, and the city's compliance with the European Green Deal was evaluated. Firstly, Landsat 8 satellite images were radiometrically corrected with the Quantum GIS software. Then, NDVI was produced using the Red-Green-Blue and Near-Infrared bands of the processed data obtained. Finally, the NDVI image with a value between -1 and +1 was reclassified to define urban open green spaces. The classification data showed that open green areas have a nonhomogeneous distribution throughout the city, and the amount of green space per capita is approximately 200 m². According to the classification results of Northern Nicosia, a surface area of 475 km², the amount of green space is calculated as 16m², constituting 2.97%. Thus, it has been concluded that open green regions are denser in certain parts of the city than others and do not have a homogeneous distribution that can serve the whole town.

Avrupa Yeşil Mutabakatı Kapsamında Lefkoşa’nın Kentsel Yeşil Alan Dağılımının NDVI ile Değerlendirilmesi

Öz

Bu çalışmada, şehrin kentsel yeşil alan dağılımı belirlenmiş ve mevcut yeşil alan varlığı Avrupa Yeşil Mutabakatı kapsamında değerlendirilmiştir. Çalışmada, Landsat 8 OLI görüntüleri kullanılmış olup, görüntülere öncelikle Quantum GIS yazılımı ile radyometrik düzeltme işlemi yapılmıştır. Ardından elde edilen işlenmiş verilerin Kırmızı-Yeşil-Mavi ve Yakın Kızılötesi bantları kullanılarak Normalleştirilmiş Fark Bitki Örtüsü İndeksi üretilmiştir. Son olarak, -1 ile +1 arasında değer olan NDVI görüntüsü, kentsel açık yeşil alanları belirlemek üzere yeniden sınıflandırılmıştır. Sınıflandırma verileri, açık yeşil alanların şehir genelinde homojen olmayan bir dağılıma sahip olduğunu ve kişi başına düşen yeşil alan miktarının yaklaşık 200 m² olduğunu göstermiştir. 475 km² yüzölçümüne sahip Kuzey Lefkoşa'nın sınıflandırma sonuçlarına göre yeşil alan miktarı %2,97 olmak üzere 16m² olarak hesaplanmıştır. Böylece açık yeşil bölgelerin kentin belirli bölgelerinde diğerlerine göre daha yoğun olduğu ve tüm kente hizmet edebilecek homojen bir dağılıma sahip olmadığı sonucuna varılmıştır.
