| ABSTRACT |
|
The benthic marine algae of six localities in western coast of Korea were investigated qualitatively and quantitatively in July and August 1988, and in June 1989. A total of 85 species of marine algae(12 blue-green. 18 brown and 41 red algae) were identified, including two species newly recorded from Korea. Among the six localities investigated in the study, marine algal biomass per unit area was highest at Tonghori (127.23 g-dry wt/m super(2)). Based on the cluster analysis of floristic data, six localities can be divided into two groups; one group comprises Muchangpo. Chaesokkang and Tonghori with relatively low turbidity, and the other comprises Oshikto, Pijakto and Taesari representing high turbidity due to mud. DCA ordination for fifty marine algal floristic data of western coast indicated that the first DCA axis mainly distinguishes mainland and island and. on the other hand, a north-south gradient is evident on the second axis. As the localities with the similar range of turbidity are grouped together, it is assumed that the vegetation of intertidal benthic marine algae in western coast of Korea depends largely upon the variation of turbidity of seawater among the various environmental factors.
