摘　　要：在防火戒严期对昆明地区11种园林木本植物的新叶片和两种对比植物老活叶片进行了垂直燃烧实验,测定了含水率、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、质量损毁程度等因子。结果表明:桂花(Osmanthus fragrans)、腊梅(Chimonanthus praecox)、青榨槭(Acer davidii)、鹅掌楸(Liriodendron chinensis)的燃烧速率和损毁程度较其余几种更强,其余7种植物活叶片差异不大。燃烧速率和损毁程度最弱的为马蹄荷(Exbucklandia populnea)和喜树(Camptotheca acuminata),其中,桂花老叶和腊梅老叶燃烧速率和损毁程度高于新叶。To understand the new leaves combustibility of different garden woody species,combustion experiments of 11 woody species new leaves and 2 comparison trees old leaves were conducted during the peak fire season. The combustion experiments measured such factors as moisture content,mass area ratio, burning linear rates,burning area rates,burning mass loss rates,vein damage degree,area damage degree, mass damage degree,etc. The results showed that the burning rates and damage degree of Osmanthus fragrans,Chimonanthus praecox,Acer davidii,Liriodendron chinensis were stronger than the others,the difference of the remaining 7 kinds of plants burning rates and damage degree were not significant. The burning rates and damage degree of Exbucklandia populnea and Camptotheca acuminate were the lowest, the burning rates and damage degree of Osmanthus fragrans old leaves and Chimonanthus praecox old leaves were stronger than their new leaves.
