摘　　要：为了比较不同园林绿化树种鲜叶的燃烧性差异,对昆明地区12种园林绿化树种鲜叶的含水率、热值、抽提物含量和灰分含量4个理化因子进行了实验测定。利用多元统计方法和系统聚类法,对鲜叶的燃烧性进行了综合评价。分析表明,12种木本植物鲜叶的燃烧性从大到小的顺序依次为桂花(Osmanthus fragrans)、桉(Eucalyptus robusta)、滇润楠(Machilus yunnanensis)、滇青冈(Cyclobalanopsis glaucoides)、云南樟(Cinnamomum glanduliferum)、竹柏(Podocarpus nagi)、蓝桉(E.globulus)、球花石楠(Photinia glomerata)、红叶石楠(P.fraseri)、阴香(C.burmanni)、枇杷(Eriobotrya japonica)、山玉兰(Magnolia delavayi),其中易燃类有5种,可燃类有6种,难燃类有1种。结论可为城市森林火灾预防提供参考。In order to compare the combustibility of fresh leaves of different landscaping tree species,the moisture content,calorific value,extract content and ash content of fresh leaves of 12 landscaping tree species in Kunming area were measured experimentally.The combusting properties of fresh leaves were evaluated by multivariate statistical method and systematic clustering method.The analysis showed that the combustibility of fresh leaves of 12 woody plants was in order from large to small:Osmanthus fragrans,Eucalyptus robusta,Machilus yunnanensis,Cyclobalanopsis glaucoides,Cinnamomum glanduliferum,Podocarpus nagi,Eucalyptus globulus,Photinia glomerata,Photinia fraseri,Cinnamomum burmanni,Eriobotrya japonica,Magnolia delavayi.There are 5 types of flammable,6 types of combustible and 1 type of difficult-flammable.This is conclusion that it can provide reference for urban forest fire prevention.
