20种园林绿化树种活枝叶的燃烧性研究

为比较植物的燃烧性,用自行设计的燃烧试验装置对20种园林绿化植物的鲜枝叶进行燃烧试验,在测定和分析样品引燃时间、有焰燃烧阶段烟气温度变化和质量损失过程等的基础上,提出了植物的燃烧性参数P.根据P值大小得出这20种园林绿化植物枝叶燃烧性由小到大的排序为:垂丝海棠、云南含笑、亮毛杜鹃、垂柳、马蹄荷、球花石楠、华东茶、翠柏、墨西哥柏、岷江柏木、云南樟、滇青冈、女贞、夹竹桃、柳杉、滇润楠、桂花、园柏、雪松和樟树.

Combustibility of living branches and leaves for 20 gardens tree species

To compare combustibility of plant species and provide theory basis for developing biological fire-prevention,combustion experimentations of living branches and leaves of 20 gardens tree species were tested with an experimental equipment designed by the authors.The combustion characteristic parameters were put forward based on lighting time,smoke temperature and weight losing in flaming stage.The order of combustibility of living branches and leaves for 20 species from strong to weak are:Malus halliana,Michelia yunnanensis,Rododerdron microphyton,Salix babylonica,Exbucklandia populnea,Photinia glomerata,Camellia japonica,Calocedrus macrolepis,Cupressus lusitanica,Cupressus chengiana,Cinnamomum glanduliferum,Cyclobalanopsis glaucoides,Ligustrum lucidum,Nerium oleander,Cryptomeria fortunei,Machilus yunnanensis,Osmanthus fragrans,Sabina chinensist,Cedrus deodara and Cinnamomum comphora.
