초안산근린공원 숲길 훼손 실태 및 복원방안 연구 (Status of Damage and Restoration Planning of Forest Trail in Choansan(Mt.) Neighborhood Park, Seoul, South Korea)

본 연구는 최근 이용압력이 높은 서울시 초안산근린공원을 대상으로 숲길의 분포왿� 훼손 실태를 파악하여 향후 도심 내 숲길 정비 방향을 설정하기 위한 목적으로 수행하였다. 초안산근린공원 숲길(25,964m)의 훼손 현황 중 노폭 2m 이상 20.3%, 침식 깊이 30㎝ 이상 36.3%, 훼손이 심한 형태인 나지침식이나 근계노출, 암석노출 구간 47.0%이었고, 환경피해도 등급 Ⅳ 이상이 70.6%로 숲길 훼손이 심각한 상태이었다. 훼손이 심한 숲길 노선은 대부분 주능선을 따라 형성된 주요 숲길과 저지대 급경사 숲길, 주요 숲길과 연결된 샛길이었다. 연구결과에 기초하여 초안산근린공원 숲길의 복원유형을 숲길 확산방지, 숲길 지반안정, 숲길 노면정비, 숲길 폐쇄 후 식생복원, 유지 등 5가지로 구분하였고, 유형별 복원방안을 제안하였다. 숲길 확산방지는 나지가 노출되어 있는 숲길 폭원 확대를 방지하고, 숲길 지반안정은 숲길 내 침식 및 뿌리노출을 방지하며, 숲길 노면정비는 훼손이 심각한 숲길의 노면을 목재데크, 목재계단, 노면 포장 실시 등을 통하여 보호하기 위한 계획을 수립하였다.

The purpose of this study targeting Choansan(Mt.) Neighborhood Park in Seoul of South Korea, whose level of visitation and use pressure has been recently increasingly high, was to understand distribution and damage status of forest trail and accordingly, set up direction of how to improve forest trail in urban area. With regards to current damage on forest trail in Choansan(Mt.) Neighborhood Park, the damaged trail with road width of over 2m and with erosion depth of over 30㎝ amounted to 20.3% and 36.3% respectively. And the trail section with bare land erosion, root exposure or rock exposure and the section whose impact rating class exceeded Ⅳ occupied 47.0% and 70.6%, indicating the forest trail was severely damaged. The severely injured trail route mainly included the main forest trail formed along the main ridge, the byroad connected to the main forest trail and the steep forest trail in low-lying area. Based on the study results, five types of restoration of forest trail in Choansan(Mt.) Neighborhood Park were offered, including prevention of forest trail extension, stabilization of forest trail base, maintenance of forest trail surface, vegetation restoration after closing forest trail and maintenance. Ecological restoration was additionally offered. The prevention of forest trail extension was planned to prevent expanded width of forest trail where bare land was exposed. The stabilization of forest trail base was planned to prevent erosion in the forest trail and exposure of roots. The maintenance of forest trail surface was planned in a way to protect the severely damaged forest trail surface by using wood deck and wood stairs and surfacing the road.
