산림토양과 갯벌의 탄소흡수량 분석을 위한 탄소 공간지도 제작

초록

This study aims to create a carbon spatial map to analyze the amount of carbon dioxide absorption on forest soils and tidal flats. First, the coefficient for forest soil in accordance with international standards was determined, and then the amount of carbon dioxide absorption of forest soil by region was estimated. The carbon absorption coefficient of tidal flats was estimated using the coefficients reported in previous studies. The areal data of forest soil and mudflats were obtained from the ‘Forest soil map’ and the ‘2018 mudflat area survey’, respectively. The result showed the total annual carbon sink of forest soil was 1,910,172.01 t C/yr, and when analyzed by province, the annual carbon sink decreased in Gyeongsangbuk-do and Gyeongsangnam-do. The decline of forest areas was the main reason for the decrease in both provinces. The total carbon sink of Korea’s mudflats was 224,723.6 t C/yr. The highest carbon sink was estimated in Incheon Metropolitan City, the second in Jeollanam-do, and the third in Chungcheongnam-do. Even though Jeollanam-do had a wider tidal flat than Incheon Metropolitan City, the carbon sink was higher in Incheon Metropolitan. As a result, this study showed the importance and potential role of tidal flats and forest soils in the realization of carbon neutrality in Korea. Also it is expected that important basic data will be used in the establishment of land management plans to achieve carbon neutrality in the future.
