Abstract

The Yeongsan River estuary, located in the south west coast, was a typical estuary before a dike was constructed in December 1981. After the construction, the water quality and plankton communities are expected to change. We investigated the change of phytoplankton community and environmental properties in the Yeongsan River estuary by comparing the data collected recently with the results reported before and/or shortly after the construction. Concentrations of $NH_4$-N were significantly increased in the freshwater zone. Concentrations of DO at the surface, $NO_2+NO_3$ and $NH_4$-N were increased while the concentrations of $PO_4$ at the surface were decreased in the seawater zone. The number of green algae species was decreased in the freshwater zone. The number of diatom species was decreased while the numbers of green algae and dinoflagellates were increased in the seawater zone. This study can provide information for better management of the Yeongsan River estuary since no comparison study has been documented between the phytoplankton community before and after the construction of the dike in the estuary.

서남해에 위치한 영산강 하구는 1981년 12월에 하구언이 건설되기 전까지 전형적인 하구의 모습을 보였다. 하지만 하구언이 건설되면서 수질뿐만 아니라 식물플랑크톤이나 동물플랑크톤과 같은 부유생물들의 생물상들도 변화를 나타낼 것으로 예상된다. 따라서 기존에 보고된 자료와 최근 채집한 현장조사 자료를 토대로 식물플랑크톤 군집과 식물플랑크톤 관련 환경인자들의 변화를 조사하였다. 하구언 건설 직후(1984년)의 환경 자료와 최근 자료를 비교 검토한 결과, 담수역에서는 암모늄이 증가하였고, 해수역에서는 표층 용존산소, 아질산염+질산염, 암모늄 농도가 증가하였고 표층 인산염은 감소한 것으로 나타났다. 식물플랑크톤 군집의 경우, 담수역에서 하구언 건설 전(1980)보다 최근에 출현한 군집이 다양해졌고, 녹조류의 종수가 감소하였다. 해수역에서는 하구언 건설 직후(1984)보다 최근에 출현한 규조류의 종수가 감소하였고 녹조류나 와편모조류 등의 종수는 상대적으로 증가하였다. 하구언 건설 전 후에 공통적으로 출현했던 종은 소수로 최근에 새로운 종들이 동정된 것으로 나타났다. 영산강 하구언 건설 전 후의 식물플랑크톤 군집 변화에 대한 조사 결과는 아직까지 보고된바가 없어, 본 논문의 연구결과는 향후 영산강 하구 생태계를 이해하고 관리하는 데 필요한 정보 및 자료를 제공할 수 있을 것으로 사료된다.
