文章以20个汉语方言点古宕摄合口三等非组字今读的韵母材料为样品,通过若干实验讨论了聚类分析在汉语方言研究中的运用问题,指出:聚类分析只是一种倚重数量关系的分析,采用的方法不同,结果也往往有差异。聚类分析虽然可以给汉语方言研究中的分类工作提供重要的参考,但倘若奉之为圭臬则未免失于偏颇。恰当的分类常常需要在综合考虑各种因素之后在定性和定量之间取得平衡。
In this paper, we use the vowels materials of the third Chinese dialect of the ancient Chinese dialect as the third-class non-grammatical characters as samples, and discuss the application of cluster analysis in the study of Chinese dialects through several experiments. It points out that the clustering analysis is only a The quantitative relationship between the analysis, the use of different methods, the results are often different. Although cluster analysis can provide an important reference for the classification work in the study of Chinese dialects, it is not biased if it is regarded as a criterion. The proper classification often requires a balance between qualitative and quantitative considerations after considering various factors.
