가로수 탄소 흡수량 추정 및 증진 전략 연구 : 서울시를 중심으로 = Carbon Absorption Estimation by Street trees and Enhancement Strategies: A Case Study of Seoul

다국어 초록 (Multilingual Abstract)

Amid the escalating global climate crisis, urban forests are increasingly recognized as critical natural carbon sinks. This study quantitatively estimates the carbon storage and annual carbon sequestration of street trees in Seoul, South Korea, and proposes practical strategies to enhance urban carbon absorption capability.
Utilizing the 2023 street tree location data obtained from the Seoul Open Data Plaza, this research conducted a systematic data preprocessing procedure. Shrubs and statistical outliers were excluded, resulting in a final valid dataset of 159,853 trees for analysis. To ensure calculation accuracy, we applied species - specific allometric equations to the eight dominant species (e.g., Ginkgo biloba, Platanus occidentalis). Crucially, to account for the physiological stress that trees endure in high-density urban environments, an Urban Correction Factor was incorporated to adjust the biomass estimations.After excluding districts with unreliable or missing key attributes, 22 districts were retained for quantitative comparison, and four representative districts were selected for in-depth case analysis.
The results indicate that the Seoul’s street trees store approximately 13,965 tC of carbon, with an annual sequestration rate of 2,075.4tC/yr. Among the species analyzed, Ginkgo biloba and Zelkova serrata were identified as the dominant contributors, collectively accounting for approximately 68% of the total carbon storage. Spatial analysis further revealed that Songpa-gu and Gangnam-gu demonstrated significantly higher carbon offsetting capacities compared to other districts, largely due to higher planting densities and a more and mature age structure.
Based on these findings, this study proposes data-driven enhancement strategies, including the selective planting of high carbon-efficiency species, the development of multi-aged structures, and intensified management for mature trees. The results provide empirical evidence to support Seoul’s "2050 Carbon Neutrality" goals and offer a practical framework for transitioning urban tree management from passive maintenance to active carbon asset management.
