| Summary: | 碩士 === 國立臺灣大學 === 園藝學系研究所 === 86 === It was due to the more demands of wetland restoration and aquatic ecosyst
em design project was emerging, the more lack of information of native aquatic
species was perceived. In addition, many endemic aquatic plants species at lo
wland plain are threatened to extinction, because of the lose of habitats
to the development. Based on these needs, the purpose of this dissertation
is to study the character of native and naturalized aquatic plants and find ou
t the patterns for waterfront planting design. It is hoped that these ideas ca
n be put into practice when landscape architects working on the waterfront res
toration and watershed planting design project. The aims of the first s
tage of the research was to review the definition, habitat, and characters of
aquatic plants. By compiling an aquatic plant list in Taiwan, and by literatur
e review, the researcher established the major structure and process for this
study. Then the researcher conducted flora survey at I-Lan,Tao-Yuan, and Taipe
i counties. What follows was the field survey at the marshes, riverines , stre
ams ,and abandoned rice fields of I-lan county to examine the vegetation
structure by transect method. All the aquatic species was analyzed according
to their basic characters, landscape characters, and ecological characters. Th
en, the design patterns of using native and naturalized aquatic plants for wat
erfront restoration are suggested. The results of this research found th
at Salix warburgii O.Seem., Lagerstroremia subcostata Koehne are suitable for
planting at riverine and pond environment. Barringtonia racemosa (L.) Blume ex
DC.,Typha spp., Polygonum orientale L.are suitable at the man-made riverine
and stream, others are appropriate either by relocating soils of seedbank or
by seeding and transplanting. The results also found that Eichhornia crassipes
Solms-Laub., Myriophyllum aquaticum (Vell.) Verdc., Gymnocoronis spilanthoide
s are suitable for botany garden and water garden, wherever display effect and
scenic management was highly demanded. The final part of this dissertation ex
plains the planting and maintenance methods for waterfront planting project.
