        북한 담수 식물플랑크톤의 분포

        이진환,이은호,이인규 ( Jin Hwan Lee,Eun Ho Lee,Eva Acs,In Kyu Lee ) 한국하천호수학회 1997 생태와 환경 Vol.30 No.4

        In order to reveal the distribution on freshwater phytoplankton of North Korea, the present study was carried out at 8 sites of inland and lake waters from 16 May to 31 May 1991. A total of 162 taxa of phytoplankton communities, representing 11 taxa 6 genera of cyanophytes, 2 taxa 2 genera of dinoflagellates, 4 taxa 3 genera of euglenoids, 1 species 1 genera of xanthophyte, 30 taxa 19 genera of chlorophytes, and 114 taxa 37 genera of diatoms, were identified. Chlorophytes were predominant in the rice field of Pyungyang, Chungchon River and Sanju Fall, cyanophytes and brackish diatoms were dominated in salt pan pool of Nampo. Sodongjung and Samil Lake were poor in phytoplankton flora but maintained a good water quality, while Mureung Fall of Mt. Myohyang was rich in biota, and suggested a poor water quality based on an ecological habit in species occurrence. Sijung Lake was abundant in brackish phytoplankton species and was thought to be exchanged by seawater. Because of disconnection of information between North and South Korea, no information on freshwater algal flora of North Korea was available for 50 years. We expect that this investigation wlll help us contribute to the understanding of a phytoplankton distribution and ecology of North Korea in part.
