摘要
对湖南莽山33种树种叶片的燃烧物理学特征值进行测定的基础上,分折了各种燃烧物理学特性对各树种燃烧的影响,确定了不同特征值的权重。用打分的方法,对供试树种的防火性能进行了综合评定。最后将供试树种划分为3个类型。为防火林带设计的树种选择提供了依据。
The physical burning characteristics values of leaves from 33 species of trees were determined in the laboratory for the purpose of choosing trees for fire protective forest belts. The influence of the values on the tree burning behavior was analysed with their weight values determined and the samples synthetically evaluated. The results show that in the aspect of burning behavior, the trees tested can be divided into 3 groups.
