摘　　要：采用Raunkiner生活型分类系统,对九顶山西坡26个样地的生活型进行统计,并编制出了生活型谱。然后尝试性地采用了SPSS软件的Hierarchical cluster方法对26个样地的生活型谱进行聚类分析,当聚类数n=5时,即将26个样地聚为5大类时,与该区原有的群落分类文献吻合性最好。从而本文在理论和实践上进一步丰富和完善了群落分类的方法。The life - form of plant communities in 26 plots on west slope in Jiuding Mountain was studied; the life-form spectra were established with the system of Raunkiner.Through the hierarchical cluster of the SPSS, that is, according to the comparability of the life - form spectra and between - groups linkage, if plant communities in 26 plots on west slope in Jiuding Mountain were classified 5 kinds, the effect is very, perfect. So the classified methods of community are enriched and perfected by clustering of life - form spectra in theory and practice.
