InVEST Carbon 모형을 활용한 수도권정비계획법 상 권역 별 토지이용변화와 탄소저장량 변화 분석

Abstract

Carbon storage is a critical ecosystem service function and has recently been affected by land use change and urbanization. In this study, the change in carbon storage was estimated by analyzing changes in land use by region under the Seoul Metropolitan Area Readjustment Planning Act and utilizing the InVEST Carbon model. Based on this analysis of land use change, the Overconcentration Control Region (OCR) showed low urban growth rates and low deforestation rates; the Growth Management Region (GMR) showed high urban growth rates and high deforestation rates; and the Nature Preservation Region (NPR) showed high urban growth rates and low deforestation rates. The smallest loss in carbon storage occurred in the NPR, while significant losses were observed in OCR and GMR. According to our analysis considering carbon sink, the amounts of above and below biomass increased slightly, but the amounts of soil carbon and dead organic matter significantly decreased. This study highlighted land use and carbon management in two ways. First, the region
