Abstract

|
Structure and dynamics of the phytoplankton communities of Uiam lake. Korea, was investigated.
In the Uiam lake four dominant species were found Oscillatoria limosa at Chuncheon City side, O. tenuis at Soyang river side, Melosira italica at south-east side and Asterionella gracillima at west side of the lake.
By cluster analysis, based on the similarity index and dissimilarity index, the phytoplanktons in this lake were grouped into three communities; i.e. Oscillatoria, Melosira and Asterionella community. And also the same groups obtained by the cluster analysis were recognized by polar ordination technique along polluted degree gradient.
It is clear that Oscillatoria community occur in polluted site, Asterionella community in unpolluted site and Melosira community in less polluted site.
