My-Tree Modeli ile Kentsel Ağaçların 20 Yıllık Karbon Sekestrasyon Dinamikleri ve Ekosistem Hizmeti Değerlerinin Nicel Modellemesi: Bingöl Kültür Parkı

Öz

Bitki türleri, kullanıldığı peyzaj uygulamalarına, yalnızca estetik ve rekreasyonel değer sunmakla kalmayıp aynı zamanda iklim değişikliğiyle mücadele, karbon depolama ve hava kalitesinin iyileştirilmesi gibi sürdürülebilir çevre yönetimi hedeflerine de katkı sağlamaktadır. Bu nedenle ağaçlandırma ve doğal tür kullanımının artırılması, uzun vadeli çevresel planlamalarda stratejik bir öneme sahiptir. Bu çalışma, Bingöl ili merkezinde bulunan Kültür Park’ta bulunan toplam 353 ağacın sağladığı ekosistem hizmetleri i-Tree (My- tree) analiz yöntemi kullanılarak nicel olarak değerlendirilmiştir. Analiz sonuçlarına göre ağaçların yıllık toplam ekosistem hizmeti değeri 388,08 $ olarak hesaplanmış, 20 yıllık süreçte ise bu değerin 8.576,96 $’a ulaşacağı öngörülmüştür. Ağaçların yıllık yaklaşık 98.749 libre CO₂ eşdeğerini atmosferden uzaklaştırdığı ve 20 yıllık dönemde yaklaşık 2.181.435 libre CO₂ eşdeğeri karbon depoladığı belirlenmiştir. Toplam birikimli değerlere göre ise 5.738.958 libre CO₂ eşdeğeri karbonun depolandığı tespit edilmiştir. Ayrıca ağaçların hava kirliliğinin azaltılmasına katkı sağladığı ve özellikle ozon ile azot dioksit gibi kirleticilerin giderilmesinde etkili olduğu ortaya konulmuştur. Eşdeğer analiz sonuçları, ağaçların karbon tutumunun ulaşım kaynaklı emisyonların dengelenmesinde önemli bir potansiyele sahip olduğunu göstermektedir.

My-Tree-Based Quantitative Assessment of Long-Term (20-Year) Carbon Sequestration and Ecosystem Services of Urban Trees: Evidence from Kültür Park, Bingöl

Öz

Plant species used in landscape applications not only provide aesthetic and recreational value but also contribute to sustainable environmental management goals such as combating climate change, carbon sequestration, and improving air quality. Therefore, increasing afforestation efforts and the use of native species holds strategic importance in long-term environmental planning. This study quantitatively evaluated the ecosystem services provided by a total of 353 trees located in Kültür Park in the city center of Bingöl Province using the i-Tree (MyTree) analysis method. According to the analysis results, the total annual ecosystem service value of the trees was calculated as $388.08, and it is projected to reach $8,576.96 over a 20-year period. The trees were found to remove approximately 98,749 pounds of CO₂ equivalent from the atmosphere annually and to sequester approximately 2,181,435 pounds of CO₂ equivalent over a 20-year period. Based on cumulative values, a total of 5,738,958 pounds of CO₂ equivalent carbon has been stored. Additionally, the trees contribute to air pollution mitigation, particularly through the removal of pollutants such as ozone and nitrogen dioxide. The equivalent analysis results indicate that the carbon sequestration capacity of the trees has significant potential to offset transportation-related emissions.
