초록

본 연구는 서울시에서 도로 방향과 가로수 식재형태가 여름철 도시 열환경에 미치는 영향을 분석하여 최적의 식재방식을 찾는 것을 목표로 하였다. 컴퓨터 시뮬레이션 프로그램 ENVI-met을 이용하여, 도로 4방향과 가로수 식재형태에 따라 68가지 시나리오를 수행하였다. 그 결과, 수목 식재 시 기온, 평균복사온도, 인간 열환경지수가 개선되는 것으로 나타났다. 평균복사온도의 감소는 도로와 접한 건물에 의한 태양 복사에너지 차단과 수목의 그늘효과에 기인하였으며, 도로방향은 풍속 감소에 영향을 주는 것으로 나타났다. 모든 시나리오에서 낮은 수고(6m), 넓은 수관폭(9m), 높은 엽면적 지수(3.0), 좁은 식재간격(8m)일 때 가장 큰 열환경 개선효과를 보였다. 도로 방향은 동-서 방향의 북측 보도에서 열환경이 가장 크게 개선되었다. 본 연구는 컴퓨터 시뮬레이션을 이용해 현실도시공간과의 차이를 감안해야 하고, 현장 실측과 더 많은 변수 고려를 통한 추가연구가 필요하다.

This study aimed to identify the optimal street tree planting method to improve the summer thermal environment in Seoul, Republic of Korea. The effects of road direction and street tree planting patterns on urban thermal environments using ENVI-met simulations were analyzed. The 68 scenarios were analyzed based on four road directions and 17 planting patterns. The results showed that tree planting had a reducing air temperature, mean radiant temperature, human thermal sensation (PET and UTCI). The most effective planting pattern among all scenarios was low tree height (6m), wide crown width (9m), high leaf area index (3.0), and narrow planting interval (8m). The largest improvement in the thermal environment was the northern sidewalk of the east-west road. Since this study used computer simulations, the difference from real urban spaces should be considered, and further research is needed through field measurement and consideration of more variables.
