森林火灾严重破坏森林资源,威胁生命财产安全,造成巨大损失。火环境是森林燃烧的重要条件,分析森林火灾发生的林火环境,对于研究林火行为,采取有效林火管理政策具有重要的理论和实践意义。在搜集凉山州气象数据、森林资源数据、地形数据的基础上,从可燃物、气象条件、地形条件3个方面分析凉山州森林火灾的火环境特征,并针对凉山州森林火环境特点,提出加大防火宣传力度、加强森林可燃物管理、加强森林经营管理、完善基础设施建设、提升应急处置水平等对策,以期提升凉山州森林火灾防控能力及林火管理水平。

Forest fire has seriously damaged forest resources,threatened the safety of life and property,and caused huge losses.Fire environment is an important condition for forest burning.Analyzing the forest fire environment is of great theoretical and practical significance for studying forest fire behavior and adopting effective forest fire management policies.On the basis of collecting meteorological data,forest resource data and topographic data of Liangshan Prefecture,this paper analyzes the fire environment characteristics of forest fire in Liangshan Prefecture from three aspects:fuel,meteorological conditions and topographic conditions.In addition,the countermeasures of forest fire management,such as strengthening fire prevention media campaign,strengthening forest fuel management,strengthening forest management,improving infrastructure construction,and improving emergency response level,were put forward.The research results can provide basis for fire behavior analysis and forest fire management in Liangshan Prefecture.
