碩士 === 國立屏東科技大學 === 森林系 === 94 === The study area was located in compartments No. 35-37 of Tawu working circle, Forest Bureau, and 42 plots of 400 m2 were sampled at elevations of 200~1,600 m. Fourteen environmental variables were measured and estimated for each plot. The aims of this study were to classify the major vegetation types and to explore the major variables influencing vegetation distribution. Plant communities were classified using two-way indicator species analysis. Vegetation types related to environmental variables were evaluated by Duncan significant test. Furthermore, species- environment relationships were examined using detrended correspondence analysis and canonical correspondence analysis. The significance levels of the eigenvalues of the gradient axes and environment variables were tested using Monte Carlo permutation. Results of the floristic data showed that 823 vascular plants, including 45 rare species were found. The plant communities were classified into five vegetation types and two subtypes. The first two ordination axes were significant, and altitude and slope were the most important variables explaining the floristic variation and community types.
