폭우에 대한 도시 기후탄력성 제고를 위한 그린인프라 평가체계 구축방안 연구 = A study on a green infrastructure evaluation system for enhancing urban climate resilience to heavy rainfall

다국어 초록 (Multilingual Abstract)

Urban climate resilience, which involves transforming cities to adapt to climate change, has gained significant attention in recent years. Although previous research has explored urban climate resilience, the inherent complexity and constant evolution of urban environments present challenges for quantitative approaches. This study focuses specifically on 'heavy rain' the most damaging climate event and 'green infrastructure,' a crucial component of urban climate resilience. It introduces a conceptual framework and a quantitative evaluation methodology based on supply and demand metrics. The study posits that urban climate resilience can be enhanced as the supply of green infrastructure increases relative to demand. Demand is evaluated through factors such as precipitation, topography, land cover, and population characteristics, enabling simulations of changes due to future climate and socioeconomic shifts. Supply, on the other hand, is evaluated based on the type and area of green infrastructure, allowing the methodology to account for efforts to expand or enhance green infrastructure. The pilot application of this methodology to Suwon City, Gyeonggi-do, revealed that 43.8% of the entire area had insufficient supply compared to demand (indicating low climate resilience), and this was particularly pronounced around the Gosaek and Mangpo stations in the southern region. The study demonstrated that the calculated climate resilience values accurately reflected the actual urban space and the historical or potential damage from heavy rain.
