Abstract

|
|
Distributional pattern of vascular plant species in terms of species-area relationship and distances from their species pool on the 53 islands selected in the South Korea were studied.
From the relationship between vascular plant species and area the equation of species-area was established as the floow;
S=cA´
c=135.52
z=0.226
S; number of species
A; area of island
In the equation the Z value 0.226 is lower than those of any other localities reported in the world. Z value increased with the increasing distance from the species pool while C value decreased.
The relationships of Z and/or C and distance from species pool, D, were established;
Z=0.002D+0.176
C=-39.5logD+178.5
The tendency of common species decrease of them with the increasing islands was fitted to the Fisher´s logarithm series. Common species 50% above was 39 species, including the most common species, Pinus thunbergii. Quotient of Similarity value by SΦrensen(1948) on common species was relatively low i.e. 0.27∼0.46.
It is noticeable for their vegetation conditions that the naturalized plant as a indicator of disturbance, for example Erigeron canadensis, was widely distributed.
