Abstract： 将FARSITE火行为模型应用于丰林自然保护区林火行为预测,并根据Rothermel和Rinehart制定的林火行为等级标准,编制潜在林火行为空间区划图,以探讨林火行为的空间分布特征.研究结果表明:在有可能、易发生和极易发生3个森林火险等级下,丰林自然保护区林火行为主要分布在ClassⅠ和ClassⅡ等级上,使用手工工具可能从火头控制火势蔓延；林火行为等级空间分布特征较为明显,ClassⅢ等级的火行为主要分布在区域中东部,ClassⅡ主要分布在区域中部,而ClassⅠ则主要分布在区域四周；高强度林火行为主要分布在可燃物模型为FL-Ⅰ和FL-Ⅱ,海拔为300-400m、坡度为平坡和缓坡、坡向为阳坡上.高强度林火发生在接近道路与居民点500m的区域内分布面积明显高于分布在距离道路居民点500-1000m和1000-1500m区域.
