| Summary: | 碩士 === 國立中山大學 === 生物科學系研究所 === 94 === Vegetation classification of Braun-Blanquet approach of vegetation ecology is widely accepted as a method to establish formal classification system. However, the measuring parameter commomly used by Taiwan ecologists is important value index (IVI) of Wisconsin school. The purpose of this paper is to study whether the different measuring parameters (IVI vs. cover-abundance scales) result in different vegetation classifications or not. Jhuokou River Basin was used as the studied area. Vegetation sampling data based on different parameters were analyzed by nonmetric multdimesional scaling（NMDS）and two-way indicator species analysis（TWINSAPN）and the resulted associations and alliances compared with their member plots, character species and dominant species. The results indicated that these attributes of alliances from both methods were higher regularity than associations, but further research is still needed to clarify these regularity patterns.
