Abstract

Phytoplankton standing stocks had been researched in Saemangeum water region from 2001 to 2010 belong to the construction period of Saemangeum dike. The big change of phytoplankton standing stocks was shown, reaching 57 - 85,219 cells/ml according to the sampling seasons and stations. Inside of Saemangeum lake, a flux of fresh water and sea water made the phytoplankton standing stocks changed spatiotemporally. Meanwhile, the water bloom was frequent with continuously high standing stocks of fresh water stations and the standing stocks outside of the dike have been normal. In the long-term point of view, the standing stock did not show a big change comparing to the before and after of closing the dike(April, 2006).

새만금 방조제 건설기간에 해당하는 2001년부터 2010년까지 10년간 새만금 수역에서 식물플랑크톤 현존량을 조사하였다. 식물플랑크톤 현존량은 조사 시기 및 조사 정점에 따라 57 - 85,219 cells/ml의 큰 변화를 보였다. 새만금호 내부 수역은 담수 및 해수의 유입량 변화와 계절변화에 기인하여 식물플랑크톤 현존량이 시공간적으로 변화하였다. 한편, 담수 정점들은 상시적으로 높은 현존량이 기록되어 녹조발생이 잦았으나 방조제 밖 해수역의 현존량은 보편적 범위에 있어왔다. 장기적 관점에서 방조제 물막이 공사 완공(2006년 4월)을 전후하여 비교할 때 식물플랑크톤 현존량의 큰 변화는 나타나지 않았다.
