생활권 주변에 넓게 분포하던 묵논습지와 소규모 저수지 등 마을습지들이 제대로 관리되지 못하고 훼손되거나 소멸되고 있음에도 보전 노력이 제대로 이루어지지 못하고 있는 실정이다. 본 연구는 세종시의 토지피복 변화에 따른 탄소흡수량을 산출하고, 세종시 생활권을 나누어 각 생활권에 분포하는 묵논습지 등 마을습지들의 기능을 평가하여 보전 관리를 위한 기초 자료를 제공하기 위해 수행되었다. 기능평가는 Park and Koo(2024)에 의해 개발된 소규모 생활권 습지기능 간편평가법(RAMS)을 적용하여 4개 평가 항목, 15개 세부 지표별로 각 5점 척도로 평가하고 기능수준을분석하였다. 토지피복별 탄소흡수량은 2009년 및 2023년 세종시 토지피복(Table 2)에 근거하여 활동자료가 제공되는농경지, 산림지, 초지 등 3개 토지피복유형 중분류를 기준으로 산출하였다. 농경지는 농경지 면적이 감소되어 2009년458,638tCO2에서 2023년 249,680tCO2로 감소하였다. 산림지역은 입목축적량이 크게 증가하여 636,189tCO2에서1,866,959tCO2로 증가하였다. 초지는 산림지역의 토지이용 전환에 따라 인공초지 면적이 증가하여 38,298tCO2에서277,036tCO2로 증가하였다. 습지 기능은 탄소흡수(F4) 기능(3.65)이 가장 ‘우수’하게 나타나 묵논습지 등 마을습지의탄소 축적 및 탄소흡수 기능이 다른 기능에 비해 뛰어난 기능임을 알 수 있었다. 그외 생물다양성 및 건강성(F1) 기능(3.10)과 친수문화 및 생태성(F3) 기능(3.10), 물순환(F3) 기능(3.00)은 ‘보통’ 수준으로 나타났다. 15개 세부지표 중에서는 F21(접근성 및 시각적 개방성), F34(수문침수), F41(토양유기탄소 집적), F42(탄소흡수․저장 식생형), F43(주변토지피복 탄소흡수) 등으로서 F2 1개 지표, F3 1개 지표, F4는 3개 지표에서 모두 높게 나타났다.
Abstract
Although village wetlands, such as abandoned paddy wetlands (APWs) and small reservoirs, are widely distributed around residential areas, they are often poorly managed, leading to damage or disappearance. Conservation efforts have not been adequately implemented. This study calculates carbon absorption associated with land cover changes in Sejong City and evaluates the functions of village wetlands, including APWs, across different residential areas. The analysis uses the RAMS method in small-scale residential areas, assessing four evaluation criteria and 15 detailed indicators on a 5-point scale. Carbon absorption by land cover type was calculated based on three categories— agricultural land, forest land, and grassland—using land cover data from Sejong City for 2009 and 2023. Agricultural land decreased from 458,638 tCO2 in 2009 to 249,680 tCO2 in 2023 due to a reduction in agricultural land area. In contrast, forest areas significantly increased from 636,189 tCO2 to 1,866,959 tCO2, reflecting a substantial rise in standing timber stock. Grassland also saw an increase from 38,298 tCO2 to 277,036 tCO2 due to the expansion of artificial grasslands resulting from land-use changes in forest areas. The carbon absorption function (F4) was rated the highest at 3.65, indicating that the carbon accumulation and absorption capabilities of village wetlands, such as APWs, surpass other functions. Additionally, the ‘biodiversity and health’ function (F1) received a score of 3.10, while both the ‘water-friendly culture and ecology’ (F3) and ‘water cycle’ functions (F3) scored 3.00, reflecting average performance. Among the 15 detailed indicators, F21 (accessibility and visual openness), F34 (hydrological inundation), F41 (soil organic carbon accumulation), F42 (carbon absorption and storage vegetation type), and F43 (surrounding land cover carbon absorption) were rated high in one F2 indicator, one F3 indicator, and three F4 indicators.
