摘 要 ：Though it is efficient using mathematical approch to the classification of plant communities, yet the general mathematical means does not satisfy the needs of community classification of subtropical evergreen broad-leaf forest. In this paper the author discussed the effectiveness and deficiency of the ’Importance Value’ in naming and classifying the evergreen broad-leaf forest and suggested to adopt the ’Index of Similarity of Spatz (1970)’ combining with the ’Importance Value’ as the basis for classifying the subtropical evergreen broad-leaf forest.
