基于模糊综合评价法的兴安落叶松人工林采伐迹地火险等级评价∗

摘要

为评价兴安落叶松人工林采伐迹地火灾等级，经实地调研结合迹地自身特点，利用模糊综合评价法构建兴安落叶松人工林采伐迹地的火灾火险等级评价体系。通过不同层次分析，针对影响火灾发生的主要因素(可燃物状况、气象因素、地形因素及人为因素)，分析不同因素对火灾危险等级的影响，做出综合性评价，并应用模糊综合评价法建立兴安落叶松人工林采伐迹地火灾危险等级评定模型，制定其火灾危险等级评定表，为采伐迹地的火灾管理提供依据。%To evaluate the fire risk rating of Larix gmelinii logging slash, based on the field researching with com-bination of slash area’ s characteristics, the fire risk assessment system was established through fuzzy comprehen-sive evaluation method. Targeted to different influencing factors such as combustible situation, meteorology, site conditions and human factor, a comprehensive assessment could be made through influence analysis of those fac-tors. This study could provide relevant reference for improving efficiency on fire management.
