Abstract

This study quantitatively estimated the age-dependent carbon dioxide uptake of Salix nipponica by establishing a grid-based outdoor experimental plantation and conducting growth measurements and destructive biomass sampling of one- to three-year-old willows. Based on the estimated component biomass, age-based averaged annual production, increment-based production, and carbon dioxide uptake were calculated. The age-based averaged annual total carbon dioxide uptake was 0.3, 3.89, and 7.82 tCO₂ ha^-1yr^-1in one-, two-, and three-year-old willows, whereas the increment-based total carbon dioxide uptake was 0.3, 6.66, and 13.81 tCO₂ ha^-1yr^-1, respectively. For two- and three-year-old willows, the increment-based carbon dioxide uptake was higher than the age-based averaged annual carbon dioxide uptake, indicating that uptake estimates may differ depending on the calculation approach when biomass increment is not evenly distributed across ages. Using the individual-tree data, species-specific allometric equations relating basal diameter to organ and whole-plant biomass were derived; basal diameter alone explained 87.2% of the variation in ln-transformed total biomass and in ln-transformed below-ground biomass, providing a non-destructive basis for estimating stand-level early-stage carbon accumulation, although leave-one-out cross-validation showed that individual-level prediction error remains large (MAPE 87.5%), so the equations are intended for stand-level mean estimation. In addition, previous field-survey-based studies of Salix nipponica communities in Korean rivers and riparian zones were reorganized on a common above-ground carbon dioxide uptake basis and compared with the results of this study. The reviewed same-species data with age information showed that above-ground carbon dioxide uptake generally increased with individual growth as age increased, although the increase slowed or decreased in some older stands due to decreasing tree density. This study provides comparable destructive-harvesting-based and field-survey-based data, together with species-specific allometric equations, as baseline information for evaluating riparian carbon sinks.

본 연구에서는 선버들의 수령별 이산화탄소 흡수량을 정량적으로 추정하기 위하여, 격자형 야외 선버들 생육장을 구축하고 1–3년생 선버들을 대상으로 생장 특성 조사와 직접수확 기반 생물량 산정을 수행하였다. 산정된 부위별 생물량을 바탕으로 수령 기반 연평균 생산량, 증가량 기반 생산량 및 이산화탄소 흡수량을 산출하였다. 분석 결과, 수령 기반 연평균 총 이산화탄소 흡수량은 1년생 0.3, 2년생 3.89, 3년생 7.82 tCO₂ ha^-1 yr^-1로 산정되었으며, 증가량 기반 총 이산화탄소 흡수량은 각각 0.3, 6.66, 13.81 tCO₂ ha^-1 yr^-1로 나타났다. 1년생을 제외한 동일 수령에서 증가량 기반 이산화탄소 흡수량은 수령 기반 연평균 이산화탄소 흡수량보다 크게 산정되어, 생물량 증가가 수령별로 균등하게 이루어지지 않을 경우 이산화탄소 흡수량 평가 결과가 달라질 수 있음을 확인하였다. 아울러 개체별 자료를 이용하여 기저직경 기반 부위별 및 총 생물량 상대생장식을 도출하였으며, 기저직경 단일 변수로 로그 변환된 총 생물량 및 지하부 생물량 변동의 87.2%를 설명하여 초기 생장 단계 선버들의 탄소 축적량을 비파괴적으로 추정할 수 있는 근거를 제시하였다. 다만 leave-one-out 교차검증 결과 개체 단위 예측오차(MAPE)는 87.5%로 크게 나타나, 본 상대생장식은 개체별 정밀 예측이 아니라 군락 평균 추정에 적합하다. 또한 국내 하천 및 수변구역의 선버들 군락을 대상으로 수행된 현장조사 기반 선행연구 자료를 지상부 이산화탄소 흡수량 기준으로 재정리하고 본 연구 결과와 비교하였다. 재정리된 자료에서 수령 정보가 제시된 동일 수종 자료를 검토한 결과, 지상부 이산화탄소 흡수량은 수령 증가에 따른 개체 생장과 함께 대체로 증가하였으나 일부 고수령 자료에서는 수목밀도 감소의 영향으로 증가폭이 둔화되거나 감소하는 양상도 나타났다. 본 연구는 직접수확 기반 자료와 현장조사 기반 선행연구 자료, 그리고 종 고유 상대생장식을 비교 가능한 형태로 제시하여 수변구역 탄소 흡수원 평가를 위한 기초자료를 제공하고자 하였다.
