昆明地区17种园林竹鲜叶的燃烧性

  目的  比较17种园林竹鲜叶的燃烧性差异，为竹林防火提供依据。  方法  以5种常见易燃园林绿化木本植物为对照，测定和计算昆明地区17种园林竹鲜叶的含水率、单位面积质量、绝对线速率、绝对面积损失速率、绝对质量损失速率、相对线速率、相对面积损失速率、相对质量损失速率等8个指标。利用因子分析法和系统聚类法，综合评价竹叶燃烧性。  结果  17种竹鲜叶均易燃，燃烧性从大到小的顺序依次为:慈竹Neosinocalamus affinis、小佛肚竹Bambusa ventricosa、秀叶箭竹Fargesia yuanjiangensis、沙罗单竹Schizostachyum funghomii、车筒竹B. sinospinosa、青皮竹B. textilis、孝顺竹B. multiplex、野龙竹Dendrocalamus semiscandens、灰香竹Chimonocalamus pallens、灰金竹Phyllostachys nigra var. henonis、料慈竹B. distegia、紫竹Ph. nigra、椅子竹D. bambusoides、云南甜龙竹D. hamiltonii、龙竹D. giganteus、绵竹B. intermedia、油竹B. surrecta。  结论  17种园林竹中易燃的有10种，较易燃的有7种。图1表6参25

Combustibility of fresh leaves of 17 species of garden bamboo in Kunming

  Objective  Comparing the combustibility of fresh bamboo leaves in gardens, in order to protect bamboo forest.  Method  Taking 5 common flammable woody plants as control, the moisture content, mass per unit area, absolute line rate, absolute area loss rate, absolute mass loss rate, relative line rate, relative area loss rate and relative mass loss rate of 17 species’ fresh bamboo leaves in Kunming were measured and calculated. The combustibility of bamboo leaves was evaluated by factor analysis and systematic clustering.  Result  All the fresh bamboo leaves of 17 species were inflammable, and the order of combustibility from large to small was as follows: Neosinocalamus affinis, Bambusa ventricosa, Fargesia yuanjiangensis, Schizostachyum funghomii, B. sinospinosa, B. textilis, B. multiplex, Dendrocalamus semiscandens, Chimonocalamus pallens, Phyllostachys nigra var. henonis, B. distegia, Ph. nigra, D. bambusoides, D. hamiltonii, D. giganteus, B. intermedia, B. surrecta.  Conclusion  10 of them were highly flammable and 7 were relatively flammable.
