A Comparative Study of Vegetation Classification Based on Two Different Measuring Parameters at Jhuokou River Basin in Southern TaiwanYang, Huei-Ru 10 August 2006 (has links)
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.

A vegetation classification and description of five wetland sysems and their respective zones on the Maputuland Coastal PlainPretorius, Mathilde Luïse 14 May 2013 (has links)
The Maputaland Coastal Plain in Kwa Zulu-Natal is covered by aeolian sands . According to the
national wetland delineation manual delineating wetlands in this area is complex due to
problematic wetland soils. The aim of this study was to classify and describe the vegetation of
the different zones of the wetland systems to determine the main drivers of the plant
communities. The understanding of these complex ecosystems could assist in wetland
delineation. Twenty wetlands from five wetland systems were surveyed. The vegetation zones
of each wetland were sampled and basic environmental data were collected.
The results from this study indicate that different plant species assemblages are characteristic
for the wetland zones. However, zone delineation using vegetation composition varies between
the different wetland systems, and should be evaluated according to the system in question.
The major determinants of the vegetation communities in wetlands on the MCP are the
substrate type and hydrological regime / Environmental Sciences / M.Sc. (Environmental Management)
