碩士 === 國立中山大學 === 生物科學系研究所 === 93 === Tai-Ma-Li Experimental Forest is located at Chinfeng Hsiang in Taitung Country, with the altitudes range from 350 m to 1450 m, and with the topical and subtopical climate. The author had set up 54 plots to investigate the composition of natural broadleaved forest. The vegetation data analyzed by detrended correspondence analysis(DCA) and two-way indicator species analysis(TWINSPAN) classified the sampling plots into four forest types: I. Machilus thunbergii－Castanopsis carlesii forest type. It was found 1040 m to 1430 m alt., and mainly at ridge or gentle slope. II. Machilus konishii－Dysoxylum hongkongense forest type. It was found from 916 m to 1255 m alt., and mainly at steep slope or valley. III. Lagerstroemia subcostata－Machilus kusanoi forest type. It was found from 456 m to 860 m alt., and mainly at steep slope or valley. IV. Dendrocnide meyeniana－Ardisia sieboldii forest type. It was found from 442 m to 803 m, and mainly at ridge or slope. The study results of correlations among environmental gradients and ordination axes indicated that the elevation, aspect and slope are the most important environmental factors affected the vegetation composition and distribution. Topographic position also has significant correlation with vegetation types.
