摘　　要：[目的]评价四川省常见的树种枝叶的燃烧性。[方法]选择70个四川省常见的生态/用材/经济树种为研究对象,分别测定其枝条及叶片的燃点、热值、灰分、粗脂肪含量和含水率,通过主成分分析,综合评估各树种枝叶的燃烧性。[结果]不同物种间,枝叶的燃烧性差异显著。燃烧性较强的物种有油松、湿地松等,燃烧性较低的物种有杧果、苹果等。[结论]该研究为四川省的森林防火提供了数据支撑,低燃烧性物种可作为潜在防火树种。[Objective]To evaluate the flammability of branches and leaves of common tree species in Sichuan Province.[Method]Seventy common ecological/timber/economic tree species were selected.Ignition point,heat value,ash content,crude fat content,and moisture content of branches and leaves were measured.Principal component analysis was used to evaluate the flammability of tree species comprehensively.[Result]Flammability varied significantly across different species.High flammable species include Pinus tabuliformis,Pinus bungeana,etc.,low flammable species include Mangifera indica and Malus spectabilis,etc.[Conclusion]This study provides data support for forest fire prevention in Sichuan Province,and tree species with low flammability can be used as potential fire-resistant species.
