초록

본 연구는 2013년 7월 부터 2015년 7월 까지 서울시 노원구 불암산 도시자연공원의 잔존림으로 남아있는 식생보전지와 교란 후 복원된 생태복원지에서 수목의 흉고직경을 측정하여 탄소 저장량 및 흡수량을 산정하여 비교, 분석하였다. 상수리나무군락을 중심으로 한 생태보전지의 수목의 밀도는 약 30 개체/225 ㎡로 쪽동백나무, 갈참나무, 노린재나무, 물푸레나무, 진달래 등 약 20여종의 수종이 분포하고 있는 것으로 나타났다. 그 외 생태복원지는 대표적으로 신갈나무군락, 졸참나무군락, 물푸레나무군락 등으로 조성되었고, 식재밀도는 각각 8.3, 7.7, 14.3 개체/25 ㎡로, 신나무, 팥배나무, 생강나무, 진달래 등 약 10여 종의 식생이 분포하는 것으로 조사되었다. 식생보전지와 생태복원지에서 식생에 의해 저장되는 전체 탄소량은 각각 250.77, 19.3 ton C ha-1로, 연간 전체 탄소흡수량은 각각 10.28, 2.33 ton C ha-1 yr-1로 분석되었다. 이는 도시내 녹지의 탄소흡수능 및 탄소수지 모니터링의 중요한 기초 자료를 제공할 것으로 판단된다.

We present a quantitative survey of the carbon storage and absorption capacity of tree species in the vegetation conservation and ecological restoration areas of Bulamsan urban nature park in Nowon-gu, Seoul. The density of the sawtooth oak (Quercus acutissima) community in the ecological conservation area is approximately 30 individuals/225 ㎡, while a further 20 species, such as Japanese snowbell (Styrax obassia), galcham oak (Quercus aliena), Asian Sweetleaf (Symplocos chinensis f. pilosa), East Asian ash (Fraxinus rhynchophylla), and Korean rhododendron (Rhododendron mucronulatum) are sparsely distributed. In contrast, the ecological restoration sites typically comprised Mongolian oak (Quercus mongolica), jolcham oak (Quercus serrata), and East Asian ash (Fraxinus rhynchophylla) plantations, with planting densities of 8.3, 7.7, and 14.3 individuals/25 ㎡ , respectively. Approximately 10 species, including Amur maple (Acer tataricum subsp. ginnala), Korean mountain ash (Sorbus alnifolia), Japanese spice bush (Lindera obtusiloba), and Korean rhododendron (Rhododendron mucronulatum) were identified in the ecologically restored area. The total amounts of carbon stored by the trees in the vegetation conservation and ecological restoration sites are 250.77 and 19.3 t C ha-1, respectively, and the total annual carbon uptakes are 10.28 and 2.33 t C ha-1 yr-1, respectively. The survey results are expected to provide important basic data for monitoring the carbon absorption capacity and carbon balance of green areas in the city.
