森林火灾逃生路径网络决策研究

A decision-making study about multi-escaperoute network generating in forest fire

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.
