碩士 / 國立中興大學 / 植物學系 / 83 / Vegetation at coastal wetlands has changed with environment,
especially land subsidence. Floral composition, salinity, water
level, vegetation seasonal aspect and succession tendency at
some coastal wetlands in southwestern Taiwan were studied. Salt
marshes and mangroves exist at subsided areas, estuarine,
abandoned fishing pond and abandoned salt field. Vegetation
zonations at coastal wetlands are mainly dominated by salinity
and water level. Coastal vegetation shows seasonal aspects.
Vegatation cover is also fluctuated due to periodic fire,
grazing and plowing. Nevertheless, xerosere, hydrosere and
halosere all could be found according to salinity and water
level in coastal wetlands. Succession tendency has been
interrupted by subsidence, typhoon, fire, inundation, etc.
Coastal wetlands provide adequate habitats for waterfowls.
There are some rare bird species at Auku marsh. Abandoned salt
field at Suchau provides nesting site for Himantopus
himantopus; abandoned wax-apple field at Chunan serves as the
egretry of Ixobrychus cinnamomeus. For the greenery of coastal
wetlands, plant species should to highly tolerant to salt,
inundation and strong wind. Adequate woody species are
Lumnitzera racemosa, Rhizophora mucronata, Excoecaria
agallocha, Myoporum bontioides, Pittosporum pentandum, Scaevola
sericea, Hibiscus tiliaceus and Clerodendrum inerme; adaptable
herbaceous species are Sesuvium portulacastrum, Sporobolus
virginicus, Suaeda nudiflora and Atriplex nummularia.
