树种防火性能的灰色关联分析及综合评价

The Grey Relational Analysis on Fireproof Performance of Trees and its Comprehensive Evaluation

应用灰色关联分析法,选择与抗火性能有关的含水率、灰分、树高、疏密程度和适应性为评价因素,对山杨、接骨木和日本落叶松等13个树种的抗火性能进行了定量综合评价。结果表明:接骨木防火性能最好,杉木次之,山茱萸最差。

Using grey relational analysis method and selecting moisture content, crude ash, tree height, sparse dense degree and adaptability as evaluation factors, the fireproof performance of thirteen trees including Populus davidiana, Sambucus williamsii, Larix kaempferi were quantitatively evaluated. The result showed that the strongest species with fireresistance was S. williamsii, the second was Cunninghamia laceolata and the poorest was Comus stolonifera.
