摘要:

本文应用多元统计分析中的因子分析和聚类分析方法,使用spss 10.0forwindows统计软件系统对55种树叶的6种性状进行统计分析。通过计算和分析,得出了反映树叶抗火性的顺序和类别,对于防火树种的选择有参考作用。从抗火性的结论中,可以看出因子分析和聚类分析适合抗火性的排序与分类分析。

Abstract:

Six kinds of characteristic about 55 species of leaves were analysed by applying factor analysis and cluster analysis.Through computing and analyzing,the ordering and sorting of fire resistance of leaves were obtained. So the result makes a reference function about selecting fire resistant tree species. From the conclusion of fire resistance, it may be concluded that factor analysis and cluster analysis adapt to ordering and sorting of fire resistance..
