Abstract

본 연구는 도심녹지의 대기질 영향을 정량적으로 해석하기 위해 수행되었다. 도심의「근린공원 녹지」가 가스상 오염물질인「질소산화물」과「황산화물」에 미치는 영향을 분석하였으며, 이를 위해 녹지의 대기환경영향평가 모델링시스템이 개발되었다. 모델링은 서울 도심의 대표적 근린공원이라 할 수 있는 종로구의 파고다 공원 인근지역을 대상으로 수행되었다. 모델링 결과, 도시 근린공원의 수목은 자체적으로 오염물질을 흡수 제거하여 대기질을 개선시키는 기능이 크다고는 볼 수 없지만, 상대적으로 친환경적인 토지이용형태(배출원이 거의 없고, 해당지역 및 주변지역에서 원활한 기류소통 촉진)를 유지함으로서 대기환경 악화를 억제하는 효과는 탁월한 것으로 나타났다. 대기오염이 심한 도시지역에서의 대기정책은 오염원 추가건설 제어를 위한 녹지보호정책을 우선적으로 고려해야 할 것으로 판단된다.

This study was to find out the quantitative relation between urban treed area(neighborhood parks) and the atmosphere environment in real condition, focusing the gas-phase non-reacting air pollutants(SOx and NOx) decreasing function of trees in urban area. It also developed a quantitative analysis method for evaluation of the atmosphere influence in the type of treed areas. We set up the Pagoda Park in Seoul and its neighbourhood as a modelling area to analyse air quality impacts by urban neighbourhood park trees. From the modelling result of the Pagoda Park case study, it is concluded that urban neighbourhood park has an important meaning to suppress construction of emission sources which drive the urban polluted air quality worse, even though park’s trees have relatively small air purifying function. Especially in the urban area severely contaminated by air pollutants, the first considered air quality management policy is conservation of green spaces in neighborhood park.
