Abstract

We investigated the effect of the water quality on the phytoplankton community in the 2 sites of Andong reservoir. The water temperature in 1 m and 4 m depth (LH) was changed, but the temperature in 7 m depth (HD) was constant irrespective of the season. The dissolved oxygen in LH was lower than that of the HD. The turbidity of water and pH were similar in both depths. The concentration of chlorophyll-a decreased with increased depth of water. Fifty nine phytoplankton taxa were identified and the most abundant phytoplankton group was Chlorophyceae with 25 taxa (43%). Cyanophyceae and Bacillariophyceae consisted of 17 taxa (29%) and 10 taxa (17%), respectively. Cryptophyceae had 3 taxa (5%) and Synurophyceae and Dinophyceae had 2 taxa (3%) in Andong reservoir. Dominant species were Elakatothrix gelatinosa (Aug, 23) and Eutetramorus fottii (Aug. 23 and Sep. 28) from Chlorophyceae, Aphanizomenon cf. flos-aquae (Aug. 16), Microcystis aeruginosa (all sampling periods), and Aphanocapsa delicatissima (Oct. 27) from Cyanophyceae, and Cyclotella stelligera (Oct. 13), Cyclotella sp. (Oct. 13 and Oct. 27) and Synedra acus (Aug. 16) from Bacillariophyceae.

본 연구에서는 안동호의 수질이 수심에 따른 식물플랑크톤 군집에 어떠한 변화를 미치는가에 대해 이해하는 연구의 일환으로 안동호의 2개 지점(서부리, 댐축)에서 6회 시료 채취 및 조사를 한 결과는 다음과 같다. 안동호의 수질의 경우 수온은 수심 1 m와 수심 4 m는 계절에 따라 다소 변화가 나타나고 있지만, 수심 7 m의 경우에는 계절의 변화와는 크게 관계없이 일정한 범위 내에서 유지되고 있다. DO는 수심 1 m와 수심 4 m는 비슷한 수치를 나타내고 있지만, 수심 7 m는 수온이 낮아지면서 DO는 증가하였다. pH와 탁도는 모든 수심(수심 1 m, 수심 4 m, 수심 7 m)에서 일정한 수치를 나타내고 있고, SiO2-Si는 수심과는 커다란 연관성 없었으며, Chl-a는 수심이 깊어질수록 그 수치가 낮아지고 있다. 따라서 수심이 깊어질수록 DO, pH, SiO2-Si, Chl-a의 수치가 수심 1 m에 비해 조금씩 낮아지고 있으며, 변화의 폭도 크게 나타났다. 안동호에서 출현한 식물플랑크톤은 모두 59종류였고, 녹조강이 25종류(43%), 남조강이 17종류(29%), 규조강이 10종류(17%), 은편모조강이 3종류(5%), 시누라조강과 와편모조강이 각각 2종류(3%)가 출현하였다. 우점종은 녹조강의 Elakatothrix gelatinosa (8월 23일), Eutetramorus fottii (8월 23일 및 9월 28일) 남조강의 Aphanizomenon cf. flos-aquae (8월 16일), Microcystis aeruginosa (모든 조사기간), Aphanocapsa delicatissima (10월 27일), 규조강의 Cyclotella stelligera (10월 13일), Cyclotella sp. (10월 13일 및 10월 27일), Synedra acus (8월 16일)였다.
