| Abstract |
The distribution, the dominant species and the seasonal succession patterns of phytoplankton communities in lake Soyang, lake Daecheong, lake Chungju were investigated. Following facts have been clarified through the investigation. ○ Seasonal succession patterns of phytoplankton in lake Soyang and lake Daecheong showed strong seasonality. In lake Soyang, diatoms (mainly Asterionella spp.) were abundant in winter and early spring, this diatoms were replaced by dinoflagellates(Peridinium spp.) in late spring and blue-green algae(Anabaena spp.) succeeded the dinoflagellates in summer, the winter diatoms recurred in autumn. ○ In lake Daecheong, diatoms(mainly Melosira spp.) were dominant throughout the year except summer and early autumn. In summer and early autumn, blue-green algae especially Microcystis spp. dominated and formed the algal bloom. ○ In lake Chungju, diatoms were dominant throughout the year and the blue-green algal bloom was not occurred in summer. |
