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..

Key words: Fire resistance, Factor analysis, Cluster analysis
