| 摘 要： | 本文描述两种执行群落排表分类的数学方法:X2分类法和信息熵分类法,并以德国西北部草地数据为例进行了应用和分析。结果表明这两个方法都是有效的群落排表分类方法,它们所排的群落表可直接地反映群落类型和种类组成之间的关系,体现了Braun-Blanquet传统排表法的特点。

| Abstract: | wo methods for carrying out tabular sorting classification, X2block 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. |
