Abstract

|
Vegetation types and their standing crop in the sand dune on the south coast of Korea was investigated by the method of Curtis, J.T. and McIntosh, R.P.(1951). The relationship between vegetation types and environmental factors was also analyzed.
The dominant species in the vegetations of the south coast sand dune were Carex pumila, Calystegia soldamella, Imperata cylindrica var. koenigli, Vitex rotundifolia, Ixeris repens, Carex kobomugi, Zoysia macrostachya.
The species density in the sand dune vegetation increased with the distnace from the coast, psammophyte and rhizome psammophyte decreased with the distance from the coast but other plants increased.
The standing crop of the sand dune vegetation was average 53.79g/㎡. An individual standing crop of Vitex rotundifolia and Carex kobomugl varied with the curve of secondary degree.
The salt content of the sand dune soil ranged from 2.95 to 11.78㎎%, and it was not significant differences among stands, but it was varied with the distance form the coast.
Negative relationship between warmth index and aboveground standing crop was found and the formula y￣=283.8886-2.4910X could be estimated.
