국문 초록 (Abstract)

전라북도지역을 산사태 발생지 182개소를 대상지로 선정하여 강우의 특성 및 다양한 환경인자 별로 조사하여 산사태발생 특성을 분석하였다. 전라북도 지역을 산사태 발생 수는 총 182개소였으며, 산사태 발생 평균면적은 1,859㎡, 평균 발생토사량은 4,418㎥, 평균 길이와 폭은 각각 139m와 13m로 나타났다. 산림환경인자별 산사태 발생 빈도가 높은 인자는 사면경사도 21~30°, 북쪽사면, 해발 401m~500m 이상, 종단사면 (오목), 횡단사면 (오목), 침엽수, 화성암, 토심은 15cm이하, 하천차수는 1차, 사면위치 (산복), 산사태 유형 (선상), 임종 (인공림), 수고 11m~15m, 흉고직경 중경목(17cm이상)에서 산사태 발생이 높은 것으로 조사되었다. 전라북도 지역의 산사태 발생면적과 산림환경인자와의 상관을 분석한 결과는 횡단사면 (볼록), 사면위치 (산정), 표고 (501이상), 임상 (침엽수), 모암 (퇴적암), 흉고직경 (17cm이상)과는 1% 수준 내에서 정의상관관계를 보였고, 경사 (31~40°), 모암 (화성암), 흉고직경 (6~16)에서 1% 수준 내에서 부의 상관관계를 보였다.

This study was carried out to analyze the landslide characteristics and forest environment factors on the landslide area of Jeonlabuk-do province in korea. The results obtained from this study were summarized as follows; The total number of landslide occurrence was 182 areas. The average area of landslide scar was 1,859m 2, average length of the landslides was 139m, average width was 13m. The landslides were highly occurred in igneous rock and coniferous. And also, slope gradient was 21~30°, aspect was NE, altitude was 401~500m, vertical and cross slope was concave (凹), stream order was 1 order, soil depth was 15m below, landslide type was linear, forest type was artificial. The relationship between landslide area and environmental factors was a positive correlation with cross slope (convex), position (upper), altitude (501m), forest type (coniferous), parent rock (sedimentary rock), D.B.H. (over 17cm), but was negative correlation with slope gradient (31~40°), parent rock (igneous rock), D.B.H. (6~16cm).
