摘  要：
基于BehavePlus火模型系统,对昆明西山国家森林公园6个主要林型进行火行为研究。结果表明:在坡度为25、35°的情形下,单位面积热量、火线强度和火焰长度最大都是地盘松林,而最小的始终是尼泊尔桤木(旱冬瓜)林,原因是地盘松林为灌木状态,可燃物载量大,达到了4.60 kg/m2,且水平、垂直连续性好,可燃物床厚度为0.72 m,熄灭含水率高达28.51%,而尼泊尔桤木林载量最小,只有2.15 kg/m2,不连续,可燃物床厚度为0.55 m,熄灭含水率只有9.04%;麻栎林的蔓延速率最大,为23.1和26.7 m/min,滇青冈林最小,为5.4和6.3 m/min,分别约为4.3和4.2倍。

摘  要：
From 2009 to 2012,studies by BehavePlus Fire Modeling System(BehavePlus Model) were conducted on fire behaviors by plots surveying of 6 major forest types in Xishan National Forest Park of Kunming and lab experiment.Fuel loads,fuel length,heat value of coarse woody debris of six forest types were determined.Putting these indexes into BehavuPlus fire model,fire behaviors including heat per unit area,the max rate of spread,fireline intensity and flame height were calculated.The results showed the highest values of heat per unit area,fireline intensity and flame height were Piuus yunnanensis var.pygmaea,while the lowest values were Alnus nepalensis.The reasons were as following: P.yunnanensis var.pygmaea forests were shrub,their fuel load reached 4.60 kg/m2,with well horizontal and vertical spatial distribution,and fuel thickness topped 0.72 m and its moisture content of extinction(MOE) was 28.51%,while,A.nepalensis forests were arbors,their fuel load was 2.15kg/m2,of discontinuity,and fuel thickness of 0.55m and MOE was 9.04%.The highest spread rate was Quercus acutissima forest,topped to 23.1 and 26.7m/min respectively,while the lowest was Cyclobalanopsis glaucoides forest,of 5.4 and 6.3 m/min,respectively.
