Abstract

Background: Population growth, increasing vehicle numbers, unplanned urbanization and rural-urban migration are reducing green spaces and exacerbating environmental problems such as air, water and noise pollution. In this context, university campuses serve as important small-scale urban models that play a crucial role in maintaining environmental and social well-being within urban ecosystems. Objectives: To evaluate the regulating ecosystem services provided by the tree canopy at Amasya University Hâkimiyet Campus (AUHC), such as air quality, energy savings, and carbon storage. Method: In this study, the land cover and ecosystem services of the AUHC were assessed using the i-Tree Canopy model. Six land cover classes defined for the study area (tree/shrub, grass/herbaceous vegetation, soil/bare ground, impervious buildings, impervious roads, other impervious surfaces) were assessed using 4000 random points and ecosystem services such as air quality were calculated. Results: The tree and shrub canopy covering 31.30% of the AUHC removes 261.53 kg of gaseous and particulate pollutants from the air annually, sequesters 36.57 tons of carbon, and stores a total of 918.42 tons of carbon. The economic value of these ecosystem services was calculated as $758 for air pollution removal and $44420 for carbon storage. The land cover distribution of the campus shows that 57.35% consists of impervious surfaces (buildings, roads) and 42.05% is green space. Conclusion: The tree canopy at the AUHC makes a significant contribution to ecosystem services such as improved air quality, carbon sequestration and storage, and these contributions and economic benefits could be further enhanced by increasing tree cover.

Amasya Üniversitesi Hâkimiyet Kampüsü’nün Düzenleyici Ekosistem Hizmetlerinin Değerlendirilmesi

Abstract

Arka Plan: Nüfus artışı, artan araç sayısı, plansız kentleşme ve kırsaldan kente göç, yeşil alanları azaltmakta ve hava, su ve gürültü kirliliği gibi çevresel sorunları artırmaktadır. Bu bağlamda, üniversite kampüsleri, kentsel ekosistemlerin çevresel ve sosyal refahını sürdürmede önemli bir rol oynayan küçük ölçekli kentsel modeller olarak hizmet etmektedir. Amaç: Amasya Üniversitesi Hâkimiyet Kampüsü'ndeki (AÜHK) ağaç örtüsünün sağladığı düzenleyici ekosistem hizmetlerini (hava kalitesi, enerji tasarrufu ve karbon depolama gibi) değerlendirmektir. Yöntem: Bu çalışmada, AÜHK’ndeki arazi örtüsü ve ekosistem hizmetleri, i-Tree Canopy modeli kullanılarak değerlendirildi. Çalışma alanı için tanımlanan altı arazi örtüsü sınıfı (ağaç/çalı, çim/otsu bitki örtüsü, toprak/bitkisiz alan, geçirimsiz yapılar, geçirimsiz yollar, diğer geçirimsiz yüzeyler) 4000 rastgele nokta üzerinden değerlendirildi ve hava kalitesi gibi ekosistem hizmetleri hesaplandı. Bulgular: AÜHK'nün %31,30’unu kaplayan ağaç ve çalı örtüsü, yıllık olarak havadan 261,53 kg gaz ve partikül kirleticiyi temizlemekte, 36,57 ton karbonu tutmakta ve toplamda 918,42 ton karbon depolamaktadır. Bu ekosistem hizmetlerinin ekonomik değeri, hava kirliliğini temizleme için 758$ ve karbon depolama için 44420$ olarak hesaplanmıştır. Kampüsün arazi örtüsü dağılımı, %57,35'inin geçirimsiz yüzeyler (binalar, yollar) ve %42,05'inin yeşil alanlar olduğunu göstermektedir. Sonuç: AÜHK’ndeki ağaç örtüsünün hava kalitesini iyileştirme, karbon yakalama ve depolama gibi ekosistem hizmetleri açısından önemli katkılar sağladığını, ancak ağaç örtüsünün artırılmasıyla bu katkıların ve ekonomik faydaların daha da artabileceğini göstermektedir.
