Abstract

This study aims to analyze the characteristics of ventilation corridor and propose its utilization strategies in Jeonju city in order to discuss how to utilize urban ventilation corridors as a planning factor for reducing heat wave impact and fine particle pollution. For these purposes, cold air characteristics such as cold air flow and height of cold air in Jeonju area located in the Honam Jeongmaek were analyzed and major ventilation corridors were specified. Based on them, we proposed mountain management strategies for securing and utilizing ventilation corridors. We used KALM (Kaltluftabflussmodell), a cold air simulation model developed in Germany and identified both the cold air flow and the height of cold air layer generated during 6 hours at night. As a result, the cold air flow generated in the forests located in the northeast and east sides of the Jeonju city became clear and the height of cold air layer increased in the valley terrain and farmland areas with time. In particular, Jeonju City has an ideal structure of urban ventilation corridor. Based on the results, the area where the cold air generation is active was designated as the 'cold air conservation area', and the area requiring the management for the good cold air flow was as the 'cold air management area'. This study is expected to be used as basic data of policy making and research for reducing heat wave impact and fine particle pollution such as climate change adaptation policy and urban forest plans for ventilation corridor composition.

본 연구는 폭염 및 미세먼지 저감을 위한 계획요소인 바람길의 활용 가능성을 논의해보고자, 전주시를 대상으로 바람길의 특성을 분석하고, 바람길 활용을 위한 방안을 제안하는 것을 목적으로 한다. 이를 위해, 호남정맥에 위치하는 전주지역 일대의 찬공기 흐름 및 찬공기 층 높이 등 찬공기 특성을 분석하였고, 전주시의 주요한 바람길을 특정하였다. 또한, 이를 바탕으로 전주시 일대의 산림관리 및 도시계획 활용방안을 제안하였다. 찬공기 특성 분석을 위해 독일에서 개발된 모형인 KALM(Kaltluftabflussmodell)을 이용하여 야간 6시간 동안 생성되는 찬공기 흐름 및 찬공기층 높이를 파악하였다. 분석 결과, 시간이 경과함에 따라 전주시 외곽 북동쪽 및 동쪽에 위치한 산림에서 생성된 찬공기의 흐름이 뚜렷해지고, 계곡지역과 농경지 일대에서 찬공기층의 높이가 증가하였다. 특히, 전주시의 찬공기 흐름은 북동쪽과 동쪽에서 생성된 찬공기가 전주시 중심 시가지로 유입되어 남쪽으로 흘러나가는 형태를 가지고 있어, 이상적인 바람길의 구조를 보여주는 사례였다. 찬공기 분석 결과를 바탕으로, 찬공기 생성이 활발한 산림지역 일대를 '찬공기 보전지역'으로 지정하고, 원활한 찬공기 흐름을 위해 관리가 필요한 지역을 '찬공기 관리지역'으로 지정하여, 찬공기 흐름을 유지 및 확대할 수 있는 방안을 제안하였다. 본 연구의 결과는 전주시의 기후변화 적응 정책, 바람길숲 조성 사업 등 폭염과 미세먼지 해결을 위한 정책 수립과 연구의 기초자료로 활용될 수 있을 것으로 기대한다.
