本文对杉木次生林林冠下营造细柄阿丁枫（Ａｌｔｉｎｇｉａｇｒａｌｉｌｉｐｅｓ）后形成的混交林和杉木纯林的林分燃烧性进行了定量测定与分析，结果表明：细柄阿丁枫、杉木混交林的林内相对湿度，地被物含水率，林分贮水量等指标显著高于杉木纯林；易燃危险物数量减少，且呈间歇式分布，易燃危险物生物量与有效潜在能量占林分总负荷量和总潜在能量比率明显低于杉木纯林。混交林林分的燃烧低于杉木纯林，有利于阻隔或延缓林火蔓延，在营林防火上有推广应用价值
In this paper, the burns of mixed forest and Cunninghamia lanceolata plantation, which are formed after planting canopy Altingia gralilipes under the canopy of Chinese fir secondary forest, were quantitatively determined and analyzed. The results showed that: Relative humidity, ground water content and water storage capacity of stands were significantly higher than those of pure Chinese fir plantations. The number of flammable hazardous materials decreased, and intermittently distributed. The biomass of flammable hazardous materials and available potential energy accounted for the total stand load The amount and total potential energy ratio was significantly lower than the pure Chinese fir forest. Mixed forest stand burning lower than pure Chinese fir forest, is conducive to blocking or delaying the spread of forest fire, forest fire prevention and popularization and application of value
