Abstract

We conducted a study to identify the relationships between the investigated factors and provide a methodology and generate data by applying deterioration classes to the Seonjaryeong Forest Trail (4.3 km) in the Baekdudaegan Ridge. The average trail width (1.7 m) and bare width (1.4 m) were wider than those obtained in the previous studies. The frequency of trail deterioration was also high. Specific data on deterioration classes were obtained and evaluated using qualitative criteria. Specific data for heavy class stands at 20.1% in trail grade, 13.3 cm on average, and 16.1 cm in the center of erosion depth, 16.2 cm of CSA, 12.3 kg/cm (20.1 mm) on average and maximum 39.3 kg/cm (29.6 mm) of soil hardness. We observed a positive correlation between the deterioration class and trail grade, and the average and maximum soil erosion depths of the hill side were deeper than those of the ridge. The soil hardness data showed a statistically significant difference in terms of the transect site and calculation method (㎏/㎠, mm). Therefore, trail deterioration was observed at the sites having ≥20% trail grade; thus, continuous monitoring at fixed sites over time will be required for sustainability. Furthermore, the trail grade should be of the utmost priority in trail design and management.

본 연구는 백두대간 마루금 선자령순환등산로 4.3 km에서 정성적으로 평가되는 훼손등급을 적용하여 숲길훼손이 발생된 구역의 구체적인 데이터와 조사방법을 제시하고, 조사항목간의 관계를 구명하고자 수행되었다. 그 결과, 선자령순환등산로의 평균 노폭(1.7 m)과 나지폭(1.4 m)은 지금까지 보고된 연구에 비해 매우 넓은 것으로 나타났으며, 훼손비율 또한 높은 것으로 확인되었다. 정성적인 기준으로 평가된 훼손등급에 대해 다음과 같이 구체적인 데이터를 확보할 수 있었다. 훼손등급 강의 경사도는 20.1%, 침식깊이는 평균 13.3 cm, 중앙 16.1 cm, 침식량 16.2 ㎠로 나타났으며 토양경도는 평균 12.3 kg/㎠(20.1 mm), 최대 39.3 kg/㎠(29.6 mm)로 나타났다. 훼손등급과 경사도는 양의 상관관계를 보였고, 능선보다 산복에서 평균과 중앙의 토양침식깊이가 깊어지는 것으로 나타났다. 그리고 토양경도는 횡단 측정위치와 방법에서 유의적인 차이가 있는 것으로 나타났다. 따라서 선자령순환등산로는 경사도가 20% 이상인 구간에서 훼손이 발생함에 따라 지속 가능한 이용을 위해서는 고정조사점에서의 지속적인 모니터링이 필요하다. 또한, 숲길설계와 관리에는 경사도가 우선적으로 고려되어야 한다.
