국립공원 탐방로 안전지수 및 등급분석에 관한 연구

Abstract

In this study, the safety indexing and grading analysis were conducted for 21 national parks,using the trail safety evaluation model. If any one of the risk factors around the trail was identified through a field survey, the safety index was calculated by judging it as a vulnerability zone. The vulnerability zone was 180.4km in total, and it was found to be about 9.0% compared to the total length of 1,995.5km. The safety index was distributed from the minimum of 42.3 to the maximum of 167.0, and the average value was 101.5 of total 200 scores. As a result of analyzing the grade based on the safety index, 60.8km (34%) was in the ‘Concern’ grade, 57.8km (32%) was in the ‘Caution’ grade, 49.6km (27%) was in the ‘Dangerous’ grade, and 12.2km (7%) was in the ‘Very dangerous’ grade. ‘Very dangerous’ sections were found to be a total of 12.2 km. including 6 national park trails: Bukhansan National Park (6.0km), Jirisan National Park (3.3km), Odaesan National Park (1.6km), Seoraksan National Park (0.9km), Woraksan National Park (0.4km), Songnisan National Park (0.01km). In terms of ‘Very dangerous’ section, Bukhansan National Park included Y Valley and Uisang Ridge, and Jirisan National Park included Chilseon Valley and Guryong Valley. The area of Noinbong in Odaesan National Park, and Gongnyong Ridge and Heulimgol in Seoraksan National Park were included. And the Geumsusan area in Wolaksan National Park and Makjangbong in Songnisan National Park were found to be ‘Very dangerous’. This study could be used as basic data to establish national park safety management policies, such as selecting priority of trail maintenance and establishing countermeasures to reduce disaster risk.
