Abstract

The coastal vegetation of the southwestern coast of Korea was surveyed by the Braun-Blnquet's phytosociological sKDICe and its soil properties were also determined. Comparing with the coastal vegetation of Korea, Japan and Europe, the vegetation of this area could be classified into as follows; A. Thero-Salicornietea R. Tx. 1954(Salicor-nietum herbaceae assoc. nov.). B. Thero-Suaedetea Rivas Martwez 1979 (Suaedetum japonicae Miyawaki et Ohba 1966, Suaeda maritima commuity, Atriplici-Suaedetum maritimi Miyawaki et Ohba 1965, Suaeda asparagoided community) C. Asteretea tripolium Westhoff et Beeftink 1962 (Zoysietum sinice Ohba, Miyawaki et Tx. 1973, Limonietum tetragoni Miyawaki et Ohba 1969, Artemisietum scopariae assoc. nov., Aster tripolium community, Atriplex, gmelini community) D. Phragmitetea Tx. et Prsg. 1942 (Triglochietum maritimae assoc. nov., Carcetum scabrifoliae Miyawaki et Ohba 1969, phragmites communis community, Pyaceluretum latifolii Miyawaki et Okuda 1972, Scirpus fluviatilis community) E. Salsoletea komarovil Ohba, Miyawaki et Tx. 1973(Salsola komarovi community) F. Glehnietea littoralis ohba, Miyawaki et Tx. 1973(Caricetum pumilae assoc. nov., Meserschmidia sibirica community, Lysimachia mauri-tiana community Ishaemum anthephoroides community, Elymus mollis commuity, carex kobomugi community, Ixeris repens community) G. Viticetea rotundifoliae Ohba, Miyawaki et Tx. 1973 (Imperato cylindricae-Viticetum rotundifoliae ohba, Miyawaki ex Tx. 1973) and Opuntia ficus-indica var. saboten community. Among the soil properties, water potential seems to be one fo the most important factor on the distribution of the coastal plant community and it might be highly affected by water content in sand and salinity in low marsh.
