The dynamics of phytoplankton communities were investigated for Upo wetland from march 2005 to December 2007 on monthly basis. During the investigation, totally 213 phytoplankton taxa which belonged to 86 genera of 35 families in 8 classes were observed. Chlorophyceae was the most diverse in the Upo wetland. Number of phytoplankton taxa was in the range 14${sim}$50 for monthly investigation and the average number of taxa was 34${pm}$10. Phytoplankton standing crops were the lowest value of 161 cells $mL^{-1}$ in August 2005 and the highest with 159,283 cells $mL^{-1}$ in August 2006. Especially during summer season in 2006, phytoplankton standing crops showed the highest value due to the waterbloom occurred by cyanobacteria. The number of the dominant taxa of Upo wetland were 13 and among them chlorophyceae and cyanophyceae dominated 8 times. In the view of seasonal changes of phytoplankton community, Upo wetland had high portion of cryptophyceae, dinophyceae and bacillariophyceae in the winter season and chlorophyceae and bacillariophyceae in the other season. However, in the summer season of 2006, cyanobacteria showed the highest portion. The diversity indices had range from 0.50 to 2.86 and showed the tendency of gradual decrease in each year.
