摘要
There are generally two ways to ignite wildfires, including natural fire sources represented by lightning strikes and artificial fire sources generated by human production and daily use, both of which have regional and seasonal characteristics. For three-dimensional forest fire research, it is not easy to achieve complex global spread behavior simulation while considering the internal physical reactions of vegetation combustion. The study constructed different natural scenes based on different vegetation cells, described the principle of lightning ignition of combustibles, analyzed the spread results of wildfires under the influence of multiple weather factors in different scenes, and achieved repeatable wildfire research. At the same time, the virtual scene intuitively expresses the real fire extinguishing methods, providing relevant references for the design of fire extinguishing schemes. Compared to directly using physical models, this article uses a single wood pyrolysis model to couple vegetation's morphological structure and physical reactions. By considering the spread of different vegetation types and the influence of multiple factors on forest fire spread, it expresses the complete forest fire behavior from ignition to extinction, significantly improving the realism and immersion of forest fires.
