The species and standing crops of periphytic algae attached on reed in two wetlands
(the Banwol and the Donghwa wetland) with different water chemistry were investigated
to evaluate the effect of water chemistry on the difference in communities of
periphytic algae between two wetands in Korea. Cyanophyceae was the most abundant class
ranging from 52percent to 93percent of total biomass, showing not difference between
two wetlands. However, dominant species of Cyanophyceae were different between two
wetlands, showing Phormidium faveolatum in Banwol wetland and Oscillatoria in the
Donghwa wetland. On the other hand, the water chemistry was different between two
wetlands, especially in nitrogen and phosphorus. The mean concentrations of TN and TP
at the inlet of two wetlands were 14.5 mgN/L, 0.18mgP/L in the Banwol wetland and 8.2
mgN/L, 0.44mgP/L in the Donghwa wetland, respectively. This result indicates that the
different water chemistry may affect on the community of periphytic algae attached on
plant in wetland ecosystem.
