滇中地区11种森林木本植物活叶片抗火性能
Fire resistance of live leaves of 11 woody species in Central Yunnan Province

为比较不同森林植物活叶片的抗火性能，在防火戒严期内对滇中地区11种主要森林木本植物的活叶片进行了高氧条件下的燃烧试验，测定和计算了各种植物活叶片的含水率、单位面积质量、燃烧线速率、燃烧面积速率、燃烧质量损失速率、叶脉损毁程度、面积损毁程度、质量损毁程度等共14个因子，运用因子分析方法对11种植物的抗火性能进行排序，结果表明：11种活叶片的抗火性能可分为4类，其中抗火性极差的1种，抗火性差的4种，抗火性中等的3种，抗火性强的3种。
To compare fire resistance difference of plant species,combustion experimentations of live leaves from 11 common native woody plant species in Central Yunnan Province were conducted with an oxygen index measuring instrument under high oxygen concentration during the peak forest fire season.Moistrure content,mass per unit area,burning rate,damage extent of the live leaves were measured and calculated.The combustibility orders and classification were put forward based on factor analysis.The results showed that the live leaves of 11 species were divided into four categories including very inflammable species (one kind),inflammable species (four kinds),combustible species (three kinds) and hardly inflammable species (three kinds).
