초록

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's need for land use and carbon management policies was emphasized by analyzing changes in land use and carbon storage by region. Especially, cities in the GMR with the most significant development pressure currently have fewer means of suppressing development, including establishing protected areas. There is a need to establish regional policies that can manage these issues and minimize the reduction of carbon storage. The second is the importance of soil carbon. Soil carbon accounts for the most significant portions of carbon sink. Thus, it is confirmed that the reduction of soil carbon due to urbanization of land other than forest areas has a significant impact on the total carbon volume, which is necessary for the integrated management of soil carbon.
