摘要
从理论上分析了飞火的形成过程,建立了飞火形成及传播过程的理论模型,探讨了各种因素对飞火过程的影响,给出了用诺谟图估算飞火距离的方法。这些工作对森林火灾中飞火距离的估算具有重要的理论意义和实际意义。由于飞火形成过程的复杂性,以及模型建立过程中所进行的假定等因素,本文所提出的飞火估算模型仍有待于大量的林火实践进行修正。
This paper analyzes the process of spotting fire. The theoretical model about spotting fire in a large forest fire is constructed. The effects of several factors upon the spotting distance are discussed. The nomographic, which describes the relationship between various factors and the distance of spotting fire, are drawn. Because of the complexity of the spotting fire process, the theoretical model of spotting fire should further be modified based on the practice of real forest fires.
