碩士 === 國立屏東科技大學 === 森林系所 === 96 === The aim of this study is to research the communities of Rhododendron formosanum in Ailaonan upper river. 20 plots of 0.04 ha were laid and 7 environmental factors were observed. 363 species which belong to 92 families were found in study areas. Four vegetation types were identified using detrended correspondence analysis (DCA) and two-way indicator species analysis (TWINSPAN). The vegetation types were Carpinus kawakamii type, Rhododendron formosanum type, Eurya loquaiana-Machilus japonica type and Beilschmiedia erythrophloia-Machilus thunbergii type. The stone had significant correlation with the first axis of DCA, furthermore, the altitude and topographic position had significant correlation with the second axis. Beilschmiedia erythrophloia-Machilus thunbergii type had the highest amount of species. Beilschmiedia erythrophloia-Machilus thunbergii type and Eurya loquaiana-Machilus japonica type had the highest value of Evenness index and Shannon-Wiener index. Rhododendron formosanum type had the lowest value of Simpson index.
