Abstract

The purpose of this study is to provide basic data for forest roads management by using AHP methodology to group the grade of disaster risk. In addition to this, a field study was performed at 114 targeted points on forest roads where there are high risks of disaster occurrence. The results of the field survey and the analysis of AHP were compared to provide the degree of disaster risks. It shows that the drainage facilities occupied the highest weighted value. Meanwhile, based on AHP analysis data, evaluation chart was created by providing evaluation criteria and evaluation score to each evaluation items. As a result of applying the evaluation chart to the field survey data, the highest score was 78.8 and the lowest score was 42.7 with the mean score of 61.8. Finally, through the experts' consultation based on calculated scores, this study proposed four different groups of disaster risk on forest roads.

본 연구는 임도의 재해위험 등급을 구분하기 위한 평가표를 제시하고자 수행되었으며, 이를 위해 임도의 재해에 영향을 미치는 인자들을 선정하고 산림공학 전문가들을 대상으로 AHP 설문조사를 실시하였다. 평가항목은 전문가집단의 자문을 통해 크게 자연환경, 인문 사회환경, 임도의 구성요소로 구분하였으며, 총 21개의 평가인자로 구성하였다. 설문조사결과를 바탕으로 각 평가항목에 대한 가중치 분석을 실시하였으며, 분석결과 임도의 구성요소 항목 중 배수시설이 가장 높은 가중치를 점하고 있는 것으로 나타났다. 한편, AHP 분석결과를 바탕으로 각각의 평가항목에 대한 평가기준과 평가점수를 부여하여 평가표를 작성하였다. 도출된 평가표를 현장조사에 적용시킨 결과 최고점은 78.8점, 최저점은 42.7점, 평균점수는 61.8점으로 나타났다. 산정된 점수를 바탕으로 전문가 집단의 회의를 통해 임도의 재해위험 등급을 4등급으로 구분하여 제시하였다.
