다국어 초록 (Multilingual Abstract)

Heavy rainfall is increasing landslide and flash flood risks in Korea’s national parks, requiring proactive disaster management. The Korea National Park Service has established a maintenance plan for disaster-vulnerable areas to enhance trail safety. In Jirisan National Park, the Chilseon Valley trail has seen increased visitation due to expanded reservation access. This study refined the maintenance plan through detailed field surveys and risk assessments. A total of 78 sites were investigated, and disaster risk was evaluated using field data. The Analytic Hierarchy Process (AHP) was applied to assess four factors: topography, geology, valley characteristics, and ecological value. Based on the results, priority management strategies were established for three flood-risk areas and five steep-slope zones. The upper Chilseon Valley maintains high ecological integrity, requiring careful balance between safety and conservation. Large-scale structural measures may negatively impact the landscape despite improving safety. Therefore, a tailored disaster management model reflecting national park characteristics is needed.
