Abstract

It is necessary to examine relationship between spatial patterns of forest types and characteristics of forest fires for efficient management of fire and forest. By the ecoregions of South Korea, we computed landscape indices for whole types of forests(landscape level) and pine forests(class level), and analyzed characteristics of forest fires using statistics of forest fires from 1991 to 2006. We performed canonical correlation analysis to model the relationship between the landscape indices and the statistics of forest fires. At landscape level, forest patches were larger and more complex in the ecoregions which had higher percentage of forest area. At class level, pine forest patches were more complex and closer to neighbor patches in the coastal ecoregions. The ecoregions including metropolitan areas and cities had more frequent fire occurrences per 1,000ha, while mountainous coastal ecoregions had more burned areas and faster spread of fire growth rate. The canonical correlation between the landscape indices for pine forests and the statistics of forest fires was statistically significant at the 0.05 level and explained more than 70% of the variation in fire variables. The results showed that combustion time per fire was longer in the ecoregions which had larger and more aggregated pine forest patches.

산불을 고려하여 효율적으로 산림을 관리하기 위해서는 임상분포패턴과 산불특성과의 관계 규명이 요구된다. 본 연구에서는 기후형과 산불 빈도 및 규모를 표현하는데 유용한 생태지역을 단위로, 임상분포패턴 및 산불특성을 분석하고, 두 인자 간의 관계를 살펴 보았다. 이를 위해 수치임상도의 경관분석을 통해 생태지역별 전체 임상과 산불에 취약한 소나무 임분의 분포패턴을 분석하고, 산림청의 산불통계자료를 이용하여 생태지역별 산불특성을 추출한 다음 정준상관분석을 수행하였다. 임상패치는 산림면적비율이 높은 생태지역일수록 크고 복잡하였으며, 소나무 임분은 해안지역을 중심으로 형태가 복잡하고 패치 간의 근접성이 높았다. 1,000ha 당 산불발생건수는 도시화된 생태지역에서 많았으나, 건당 피해면적과 확산속도는 낮았다. 이와 반대로 "강원해안" 등 산림비율이 높은 생태지역에서는 적은 발생건수와 넓은 피해면적, 빠른 확산속도를 보였다. 정준상관분석 결과 산불특성은 소나무 임분의 경관지수와 유의한 상관관계가 있었는데, 소나무 임분 면적이 크면서 응집된 구조를 갖는 해안 생태지역일수록 장시간 연소되어 피해면적이 큰 특성을 보였다.
