The attached algal communities comprised totally 76 taxa belong to the 5 classes. In species composition, diatoms and green algae overwhelmingly dominated the periphyton communities although their standing crops were low. During the survey period, major dominant species were Nauicula gregaria and Nau. pupla var. capitata, as 11.7% and 8.9% of total standing crop, respectively. Other subdominant species were Scenedesmus ecornis and Spirogyra weberii in green algae, Cymbella affinis, Cymbella minuta Fragilaria capucina, Melosira uarians, Nau. cryptocephala, Nau. exigua uar. capitata, Nau. gregaria, Nit. sublinearis in diatom In the seasonal appearances, S. ecornis and Oscillatoria nigra were occurred in summer, C affinis and F. capucina in autumn, and N sublinearis, and species Spirogyra weberii in winter, respectively.
