摘　　要：森林火灾中的烟气蔓延是一种极其复杂多变的过程,受多种环境因素影响,具有突发性和多变性等特点,会加剧林火发展的不确定性,降低逃生机率、造成人员伤亡,加大林火扑救工作的困难程度。选取风速、地形、温度等影响指标,分析森林火灾烟气蔓延及各指标对森林火灾烟气蔓延的影响,综合各评价各指标的影响。结合目前火灾烟气监测的科学技术装备,提出加强烟气监测、被困人员逃生等应对策略。The smoking spread in forest fires is an extremely complex and variable process,influenced by a variety of environmental factors,and characterized by suddenness and variability,which can intensify the uncertainty of forest fire development,cause casualties,reduce the chance of escape,and increase the difficulty of forest fire suppression.Based on the research progress of forest fire smoke spread at home and abroad,the research properties of forest fire smoke spread were discussed,and wind speed,terrain,temperature,etc.were selected as the evaluation indicators of smoke spread,and the influence of each index on forest fire smoke spread was analyzed.The impact of each evaluation index is synthesized,and combined with the current scientific and technological equipment for fire smoke monitoring,the response strategies such as strengthening smoke monitoring and escape of trapped people are proposed.
