초록

탄소축적량 증진을 위한 도시공원 설계 및 계획에 적합한 식재구조와 토양 관리방법에 대한 분석이 필요하다. 본 연구에서는 탄소저감에 기여하는 도시공원 설계와 관리를 위하여, 서서울호수공원과 양재시민의 숲을 대상으로 바이오매스량과 공원조성 시기 및 식재구조가 다른 조사구에서의 토양 탄소함유량을 지상부 지하부 탄소저장량의 측정을 통해 분석하였다. 대상 도시공원으로 조성시기가 다른 서서울호수공원(2009년)과 양재 시민의 숲(1986년)을 선정하였다. 식생과 토양 특성에 따른 토양 탄소함유량의 차이를 분석하기 위하여, 바이오매스량과 토양의 물리적 화학적 특성 측정을 통해 지상부 지하부 탄소저장량을 분석하였다. 바이오매스량 측정에는 상대생장식을 적용하였으며, 토양에 관해서는 토양 탄소함유량(TOC)과 pH, 양이온치환용량(CEC), 전질소량(TN), 토양 총 균수와 같은 화학적 특성을 측정하였다. 이 결과, 바이오매스량은 양재 시민의 숲이 서서울호수공원보다 높아, 조성된 지 오래된 공원의 바이오매스량이 높은 것으로 나타났다. 한편, 토양 탄소함유량은 양재시민의 숲이 서서울호수공원 보다 낮았으며, 이는 양재시민의 숲에서의 대기오염과 산성비 노출에 의한 토양의 산성화 진행에 따른 영향 때문인 것으로 분석되었다. 또한, 토양 탄소함유량은 단층식재지가 다층식재지 보다 높은 것으로 나타났다. 장기적 시점에서 볼 때, 토양 개선은 식생 생장을 도모한다. 따라서 도시공원의 토양 특성 개선을 위하여, 석회성 비료 시비에 의한 pH 조절과 답압 제어 및 낙엽층 방치에 의한 토양 양분 증진을 통한 공원관리가 필요하다.

Identification of methods to optimize the growth of a plant community, including the capacity of the soil to further sequester carbon, is important in urban design and planning. In this study, to construct and manage an urban park to mitigate carbon emissions, soil organic carbon of varying biomass, different park construction times, and a range of vegetation types were analyzed by measuring aboveground and belowground carbon in Seoseoul Lake Park and Yangjae Citizen's Forest. The urban parks were constructed during different periods; Seoseoul Lake Park was constructed in 2009, whereas Yangjae Citizen's Forest was constructed in 1986. To identify the differences in soil organic carbon in various plant communities and soil types, above and belowground carbon were measured based on biomass, as well as the physical and chemical features of the soil. Allometric equations were used to measure biomass. Soil total organic carbon (TOC) and chemical properties such as pH, cation exchange capacity (CEC), total nitrogen (TN), and soil microbes were analyzed. The analysis results show that the biomass of the Yangjae Citizen's Forest was higher than that of the Seoseoul Lake Park, indicating that older park has higher biomass. On the other hand, TOC was lower in the Yangjae Citizen's Forest than in the Seoseoul Lake Park; air pollution and acid rain probably changed the acidity of the soil in the Yangjae Citizen's Forest. Furthermore, TOC was higher in mono-layered plantation area compared to that in multi-layered plantation area. Improving the soil texture would, in the long term, result in better vegetation growth. To improve the soil texture of an urban park, park management, including pH control by using lime fertilization, soil compaction control, and leaving litter for soil nutrition is necessary.
