- W2043932241 abstract "산불 확산 패턴 분석은 산림 생태계 안정화를 이해하는데 중요한 요소이다. 하지만 규모의 문제로 인해 실제적인 실험이 불가능하여 많은 학자들이 시뮬레이션 모델을 이용하여 산불 확산의 행동기작을 이해하고 산림 피해를 예측하였다. 그러나 많은 모델들이 연료의 종류, 바람, 습도 같은 여러 환경 요소들의 복잡한 관계를 표현하는데 한계를 가지고 있다. 본 논문에서는 지형의 구조와 두 종의 나무들로 구성된 산림에서 미치는 영향을 분석하는 간단한 모델을 제안하였다. 두 종의 나무는 가연성이 높은 나무와 가연성이 낮은 나무가 있으며, 서로 다른 산불 전이 확률을 가지고 있다. 전체 나무는 시뮬레이션 공간에 0.5에서 1.0까지의 비율로 무작위로 배치된다. 가연성이 높은 나무는 가연성이 낮은 나무 보다 높은 산불 전이 확률을 가진다. 전소한 나무의 수를 기준으로 지형의 구조와 전체 나무의 밀도가 산불 확산에 얼마나 영향을 미치는지 민감도를 분석하였다. 우리는, 본 논문에서 제시한 모델이 앞으로 산불 확산 패턴을 연구하는데 유용할 것으로 기대한다. Understanding the forest fire patterns is necessary to comprehend the stability of the forest ecosystems. Thus, researchers have suggested the simulation models to mimic the forest fire spread dynamics, which enables us to predict the forest damage in the scenarios that are difficult to be experimentally tested in laboratory scale. However, many of the models have the limitation that many of them did not consider the complicated environmental factors, such as fuel types, wind, and moisture. In this study, we suggested a simple model with the factors, especially, the geomorphological structure of the forest and two types of fuel. The two fuels correspond to susceptible tree and resistant tree with different probabilities of transferring fire. The trees were randomly distributed in simulation space at densities ranging from 0.5 (low) to 1.0 (high). The susceptible tree had higher value of the probability than the resistant tree. Based on the number of burnt trees, we then carried out the sensitivity analysis to quantify how the forest fire patterns are affected by the structure and tree density. We believe that our model can be a useful tool to explore forest fire spreading patterns." @default.
