Abstract

Since the implementation of the sunset law in 2020, concerns have been raised over the reckless development of long-term non-executed urban parks. In this study, the FSDAF method and CASA-NPP model were used to evaluate the annual average NPP of long-term non-executed urban parks in Seoul. Based on this, the carbon loss and economic value were assessed under five development scenarios. The total NPP value of long-term non-executed urban parks, except for the greenbelt area in Seoul, was 4,892.18 t C. In the first scenario, the NPP and cost were 4,892.18 t C of vegetation carbon and 1.18 billion won, 2,548.55 t C of vegetation carbon and 615 million won in the second scenario, 238.94 t C of vegetation carbon and 58 million won in the third scenario, 848.38 t C of vegetation carbon and 205 million won in the fourth scenario, and 1,596.00 t C of vegetation carbon and 385 million won in the fifth scenario. These results are meaningful for evaluating vegetation carbon and economic value loss according to five different development scenarios. The results of this study are expected to be useful for the preparation of measures to minimize the impact of the development of long-term non-executed urban parks.

2020년 일몰제가 시행되면서 장기미집행공원 개발에 대한 우려가 제기되고 있다. 본 연구의 목적은 장기미집행공원이 개발됨에 따라 소실되는 탄소량과 경제적 가치를 평가하여 장기미집행공원 개발에 따른 영향 최소화 방안 도출에 근거를 제공하고자 한다. 본 연구에서는 FSDAF 시공간 영상융합기법과 CASA-NPP 모형을 활용하여 서울시 내 장기미집행공원의 연평균 NPP를 산정하고, 이를 바탕으로 5개의 개발 시나리오에 따라 소실되는 탄소량과 경제적 손실을 평가하였다. 서울시 내 개발제한구역을 제외한 장기미집행공원의 총 NPP 값은 4,892.18 t C로 나타났으며, 개발 시나리오 1에서는 4,892.18 t C, 개발 시나리오 2에서는 2,548.55 t C, 개발 시나리오 3에서는 238.94 t C, 개발 시나리오 4에서는 848.38 t C, 개발되는 시나리오 5에서는 1,596.00 t C의 탄소가 소실될 것으로 나타났으며, 각각 5개의 개발 시나리오에 따른 탄소의 사회적 비용을 계산하면 약 11억 8천만원, 6억 1천만원, 5천 8백만원, 2억 5백만원, 3억 8천 5백만원이며 개발로 인해 해당금액의 경제적 손실이 발생할 것으로 나타났다. 본 연구의 결과는 5개의 개발 시나리오를 바탕으로 장기미집행공원의 탄소 손실량과 경제적 손실을 평가하였다는데 의의가 있으며, 일몰제 이후 개발가능성이 높은 장기미집행공원 내 산림생태기능에 대한 영향 최소화 방안 마련, 개발 대안의 기초자료로 활용되기를 기대한다.
