Abstract: Two methods for carrying out tabular sorting classification, X² block classification and Information entropy classification, are introduced and applied to the analysis of grasslands in Northwest Germany in this paper. The resulats suggests that both techniques are effective and suitable for tabular sorting classification. The community tables arranged by these two techniques show the relationship between vegetation and species clearly and have identical characteristics to Braun-Blanquet methodology.
