摘要: 森林火灾是全球范围内的重大自然灾害,对生态环境和人类生命财产造成了严重威胁。为更有效地应对森林火灾,引入数字孪生理念,运用火灾动态仿真模拟软件PyroSim,耦合火源点、坡度、风速、相对湿度和环境温度5个因素,以云南某地松林为研究对象,构建微观森林火灾场景进行精细化仿真,探究各因素对森林火灾蔓延的影响,并对火灾动态过程进行仿真分析。针对固定环境参数与初始火源条件下模拟仿真的滞后性,提出了一种切片化动态仿真方法。研究结果表明,数字孪生驱动的切片化动态仿真能够更加真实、高效地反映实际森林火灾的行为特征,为森林灭火策略研究提供了重要参考。

Abstract: Forest fires are major natural disasters worldwide, posing severe threats to the ecological environments, human lives and property. To address forest fires more effectively, this study introduces the concept of digital twins and employs the fire dynamic simulation software PyroSim, coupling five factors: ignition points, slope, wind speed, relative humidity and ambient temperature. A microscopic forest fire scenario in Pinus yunnanensis forests is constructed for refined simulations, aiming to investigate the influence of these factors on forest fire spread and to analyze the dynamics fire development process. A sliced dynamic simulation method is proposed to mitigate the lag issues in simulations under fixed environmental parameters and initial fire source conditions. The research results indicate that the digital twin-driven sliced dynamic simulation can reflect the actual behavioral characteristics of forest fires in a more realistic and efficient manner, thereby providing an important references for the study of forest fire suppression strategies.
