Abstract

Blue green infrastructure (BGI) reduces the high temperatures associated with climate change and the urban heat island effects. This study aimed to determine the effect of BGI on land surface temperature (LST) in Karsiyaka district, İzmir. The surface temperatures of the study area for the summer months of 2022 (June, July, and August) were calculated with the LST index using Landsat 8 satellite images. The associated heat island effect was obtained with the heat field intensity index (HFI). The cooling effects of the 100, 200 and 300 meters buffer zones of sample BGI areas that have different characteristics were calculated using the park cooling intensity. Results determined that high-temperature areas are predominant throughout the city. The maximum average surface temperature is calculated at 46.66 °C, and minimum average surface temperature is calculated at 29.59 °C in Karsiyaka for summer months in Karsiyaka . The highest cooling effect was calculated as 1.16 °C, 1.42 °C, 2.17 °C in the 100 m, 200 m, and 300 m buffer zones, respectively, with the lowest values 0.23 °C, 0.14 °C and 0.17 °C. Blue green infrastructure units with dense canopy cover created high cooling effects. It was determined that among the sample units open spaces with little or no vegetation (sample 2 and 7) did not have cooling.

Kentsel Yüzey Sıcaklığı ve Mavi-Yeşil Altyapı İlişkisi: Karşıyaka Örneği

Abstract

Mavi-yeşil altyapı (MYA) iklim değişikliğine bağlı yüksek sıcaklıkları ve bu sıcaklıkların neden olduğu kentsel ısı adası etkilerini azaltmaktadır. Bu araştırmada İzmir kenti Karşıyaka ilçesindeki MYA’ nın arazi yüzey sıcaklığı (AYS) üzerindeki etkisinin belirlenmesi amaçlanmıştır. Bu kapsamda Landsat 8 uydu görüntüleri kullanılarak çalışma alanının 2022 yaz aylarına ait (Haziran, Temmuz, Ağustos) yüzey sıcaklıkları AYS indeksi ve buna bağlı ısı adası etkisi ise ısı alanı yoğunluk indeksi (HFI) kullanılarak hesaplanmıştır. Karşıyaka MYA birimleri arasından belirlenen farklı özelliklere sahip örnek alanların 100, 200 ve 300 metre uzaklıktaki tampon bölgelerindeki soğutma etkileri park cooling intensity (PCI) indeksi kullanılarak hesaplanmıştır. Bulgular Karşıyaka’daki yaz aylarına ait ortalama yüzey sıcaklıklarının maksimum 46,66 °C, minimum 29,59 °C ve kent genelinde yüksek ısı alanı yoğunluk indeksinin fazla olduğunu göstermektedir. Örnek MYA birimleri arasında en yüksek soğutma etkisi 100, 200 ve 300 metre tampon bölgelerde sırayla 1,16 °C, 1,42 °C, 2,17 °C en düşük değerler 0,23 °C, 0,14 °C ve 0,17 °C olarak hesaplanmıştır. Yüksek soğutma etkilerini yoğun taç örtüsüne sahip MYA birimleri oluşturmuştur. Örnek birimler arasında bitki örtüsü zayıf olan 2 ve 7 nolu açık alanların soğutma etkisi olmadığı belirlenmiştir.
