本文采用因子分析的方法，对中国营建低易燃性林带薪炭网的55种树种的可燃性进行了评价。测定了空气干燥含水率、绝对干燥含水率、着火点、灰分、热值和浸出物含量6个参数，并将其作为因子分析的变量。协方差分析表明，可以提取四个主因子来反映不同物理和化学意义下的可燃性。根据这四个因素对方差的贡献和相关参数的物理意义，这四个因素分别被称为燃烧因子、风干因子、灰分因子和绝对干燥因子。通过考虑不同样本数对因子分析方法的稳定性进行了检验，排序的变异程度表明，该方法对测定树种的总可燃性具有较高的可靠性。通过与国家技术标准推荐树种的对比，验证了可燃性评价的结果。版权所有©2008 John Wiley&Sons，Ltd.
In this paper, factor analysis is introduced to evaluate the flammability of 55 foliage species that may be used in China for construction of the fuel break network of forest strips with lower flammability. Six pyric parameters, i.e. air dry moisture content, absolute dry moisture content, ignition point, ash content, caloric value and extractive content, are measured and used as variables for factor analysis. The covariance analysis shows that four principal factors can be extracted to reflect the flammability in different physical and chemical senses. In terms of the contributions of the four factors to the variances and the physical significance of the relevant parameters, the four factors are, respectively, termed as ‘flaming factor,’ ‘air dry factor,’ ‘ash factor’ and ‘absolute dry factor.’ The stability of the factor analysis method is examined by a different number of samples considered, and the variation degrees of the orderings indicate that the method has high reliability to measure the total flammability of foliage species. The results of the flammability evaluation are verified by comparison with the recommended tree species in the Chinese technology standard. Copyright © 2008 John Wiley & Sons, Ltd.
