초록
도시열섬(Urban Heat Island; UHI)은 도시가 인근 지역에 비해 뜨거운 현상을 의미하며 도시 내부의 건물의 구성, 토지피복의 종류 등이 변화하기 때문에 발생한다. 도시열섬을 완화하기 위한 방법으로녹지공간의 조성인데, 녹지가 제공하는 냉각효과의 경우 녹지의 내부 구성 요소 및 녹지의 크기에 따라 변화한다. 본 연구는 다양한 토지피복으로 구성된 수원시를 대상으로 녹지의 크기와 녹지를 구성하는 요소들에 따른 냉각효과의 차이를 확인하고, 녹지의 인근 토지피복에 따라 녹지로부터 제공되는 냉각효과의 차이를 고찰하고자 한다. 연구 결과, 녹지의 초기 온도는 산림의 비율이 높을수록, 그리고 호수가 존재할수록낮아졌다. 냉각효과 중 하나인 냉각강도는 숲의 비율이 높을수록 강해졌지만, 초기 온도가 더 큰 영향을 미쳤다. 다만 냉각 거리는 녹지의 크기나 구성에 따라 달라지지 않음을 확인했다. 본 연구의 결과는 도시의계획 시 열섬을 완화하기 위한 녹지 설계 방안을 제시한 다는 점에 의의를 가진다.
Abstract
Urban Heat Island (UHI) is caused by an energy imbalance in urban areas, where building design and land cover contribute to its amplification. To mitigate UHI, increasing green space is one of the well known and the most effective approach. This study aims aimed to identify specific components of green spaces that lower temperatures and demonstrate the cooling effects based on their size and composition. Forests within green spaces have had a greater impact on temperature reduction due to shading and blocking solar radiation. Although lakes also contributed to temperature reduction, the effect to cooling intensity was not significant. The cooling distance does not depended on green space size or composition. The study emphasizes that initial temperature has a strongerinfluence on cooling intensity than green space size, highlighting the importance of vegetation type within green spaces to achieve a cooling effect. These findings provide valuable insights for urban planning and the design of green spaces to mitigate the effects of the urban heat island.
