Through the use of the tabular comparison method, a hierarchical vegetation classification was established. Detrended Correspondence Analysis (DCA) was applied to the data to clarify the variation of the 70 plots and search for a relationship with 5 environmental variables. The results show that the distribution of vegetation types is responding to the elevation and Whole Light Sky space (WLS). Three alliances and 9 associations were distinguished and described: (I) Cyclobalanopsis stenophylloides alliance, including Neolitsea acuminatissima - Cyclobalanopsis morii, Vaccinium randaiense - Castanopsis cuspidata and Pasania kawakamii - Cyclobalanopsis stenophylloides associations, (II) Beilschmiedia erythrophloia alliance, including Camellia salicifolia - Beilschmiedia erythrophloia, Engelhardtia roxburghiana - Cyclobalanopsis longinux and Helicia formosana - Castanopsis kusanoi associations, and (III) Machilus kusanoi alliance, including Castanopsis formosana - Machilus philippinense, Machilus zuihoensis - Schefflera octophylla and Ficus irisana - Machilus kusanoi associations.
