동해안 영일만의 조간대 해조군집

Abstract

Seasonal change in the species composition at intertidal zone of 5 different sites along the coast of Yeongil Bay were analyzed seasonally during Feb. 2005 - Jan. 2007. As a result of floristic investigation, total of 110 species, including 17 Chlorophyta (15.5%), 22 Phaeophyta (20.0%) and 71 Rhodophyta (64.5%), were identified. The common species that occurred at the 5 sites were Ulva pertusa, Grateloupia turuturu, Chondrus ocellatus and Melobesioidean algae. The values of R/P and (C+R)/P ratio of study site vegetations were 3.4 and 4.2, respectively. The values shows that the flora and phenology of marine algae of the study area is a mixed one close to the temperate flora. The importance value of algal species showing above 5 at each sampling site in Yeongil Bay were 2 Cholrophyta, 2 Phaeophyta and 8 Rhodophyta.
