森林火灾逃生路径网络决策研究

摘要

为了在紧急情况下给森林火灾扑救人员提供科学的逃生决策方案，根据动物迁移阻力因子的判断方法，选取地形起伏度、林分密度作为逃生阻力因子，并结合森林火灾中的火场分布、风场状况、安全地带分布等因素构建了森林火灾逃生路径网络决策模型。以新化县油溪乡林场历史森林火灾为案例，进行了森林火灾逃生路径网络决策应用分析，提出了多条逃生路径选择方案。研究结果能为森林火灾应急避险逃生提供有效的决策依据。%This paper has designed a forest fire survival plan which serves these people who devote themselves to forest fire fighting. Following the example of ecological corridors generating in forest, we established amulti-escaperoute network generating model which influenced by RDLS, stand density, fire distribution, wind field and safety zones. Then, for analyzing the feasibility of this multi-escaperoute network a historical forest fire generating model, we conducting an experiment in YouXi forest farm, and end up with multiple viable escape plans proposed. As conclusion:the study result can provide emergency escaping from forest fire with effective decision-making evidence.
