Abstract

This study aims to analyze the properties of cold air production and its flow of Nakdong-Jeongmaek(mountain ranges), and to suggest management strategies for Nakdong-Jeongmaek in order to enhance the green air conditioning functions of Jeongmaek. For this purpose, three study sites including Gudeoksan Mountain and the vicinity in Busan, Goheonsan Mountain and the vicinity in Ulsan, and Unjusan Mountain and the vicinity in Pohang were selected. The results found that cold air flow and its height of the three study sites were analyzed based on topographic properties and land use. Management strategies for preserving and enhancing their temperature reduction functions were suggested. The cold air produced in the vicinity of Gudeoksan was not fully developed and spread because of the high-density development at the border of Jeongmaek. Since high pressures of development are expected at the border, high conservation policies are required. In the vicinity of Goheonsan, where the agricultural complex and industrial park are located, cold air flows well throughout the entire study site thanks to fully developed cold air in the wide, flat valley. Hence, plans to maintain the current cold air flow are required, and conservation plans to mitigate future developments are also needed in the flat valley. The cold air in Unjusan and the vicinity with its complex and narrow mountain valleys gradually develops into valley bottoms. In order to take advantage of the terrain, the valley near the cold air production areas are preserved. In particular, special plans are required to prevent damage to the cold air layer near Youngcheonho Lake, where the highest height of cold air was recorded due to the closed and lower terrain feature. This study could support the establishment of systematic management plans of Nakdong-Jeongmaek to preserve and enhance its green air conditioning functions.

본 연구는 낙동정맥의 녹색에어컨 기능을 활용 확대하기 위해 낙동정맥의 찬공기 생성과 흐름에 대한 특징을 분석하고, 낙동정맥의 중요한 찬공기 생성지역 보호 및 인근 도시로의 찬공기 활용 극대화를 위한 관리방안을 제안하였다. 이를 위해, 낙동정맥 인근에 위치한 부산 구덕산 일대, 울산 고헌산 일대, 포항 운주산 일대를 대상지로 선정하여 정맥의 지형적 특징 및 토지이용에 따른 찬공기 흐름의 특징을 분석하였고, 이를 바탕으로 녹색 에어컨 기능 관리체계 구축을 위한 전략을 제시하였다. 부산 구덕산 일대는 정맥 경계에 인접한 지역에서의 고밀도 개발로 인해 생성된 찬공기가 충분히 발달하지 못하며, 시가지로 확산되지 못하고 있다. 향후 정맥 접경지역에 대한 개발 압력이 매우 커질 것으로 예상되므로, 정맥의 녹색서비스 기능 강화를 위해 높은 보전정책이 요구된다. 울산 고헌산 일대는 넓은 계곡에 위치한 농공단지와 산업단지에는 충분히 발달된 찬공기가 원활하게 유입되고 있어 현재의 찬공기 유입을 유지할 수 있는 관리방안이 필요하며, 넓고 평평한 지형으로 인해 향후 개발이 확대될 가능성이 있기 때문에 보전이 반드시 필요하다. 마지막으로 포항 운주산 일대는 복잡한 산악 및 계곡지형으로써 생성된 찬공기가 좁은 계곡을 통해 이동하면서 계곡 하단부로 갈수록 점차 발달하고 있으므로, 찬공기 생성지역 가까이에 위치한 계곡 지형을 활용해야 한다. 특히, 영천호 주변은 찬공기층이 가장 높으면서도 흐름이 가장 낮으므로 찬공기로 인한 피해를 예방하는 계획이 필요하다. 본 연구의 결과는 기후변화에 대응하기 위한 낙동정맥의 체계적인 관리계획을 수립하는데 기초자료로 활용될 수 있으며, 향후 녹색에어컨 기능산지의 양적 확대 및 보전을 위한 정맥관리 강화 등 산지의 녹색에어컨 기능을 확대하는 정책 마련에 활용될 수 있을 것으로 기대한다.
