Ordination axes partitioning,a new method for classification of plant communities, is described in this pa-per.It is based on the first m ordination axes of Detrended correspondence analysis and is a polythetic tech-nique. The outcome of its application to the classification of Vitex negundo var. heterophylla is identical tothat of fuzzy equivalence clustering and group-average clustering. It is concluded that ordination axes parti-tioning is a simple,effective methedology in vegetation study.
