Abstract

The seasonal changes in phytoplankton species composition, standing crops, dominant species, species diversity and physico-chemical characteristics in the Unmun dam were studied, from August, 2009 to April, 2010. The phytoplanktons of a total of 121 taxa were identified, the composition of phytoplankton community was characterized by a green algae and diatoms, and the quantity composition of standing crops was dominated by diatoms and dinophyceae. The diatoms Aulacoseria granulata and blue-green alga Anabaena planktonica in Summer, Peridinium voltzii in Autumn and Asterionella formosa in Winter to Spring were, especially, prominent. The seasonal changes of the biomass varied from 578 cells $mL^{-1}$ to 12,938 cells $mL^{-1}$, and the maximum algal density was observed in April, Asterionells formosa contributed to 88% of the total cell numbers. The species diversity and richness were highest during autumn, and dominance index was highest in the spring season.

2009년 8월부터 2010년 4월까지 계절별로 조사된 운문댐의 식물플랑크톤은 총 121종류였으며, 이들은 녹조류(47종류)와 규조류(45종류)가 출현종의 76%를 차지하여 가장 중요한 분류군으로 조사되었다. 조사지점별 출현종 수는 동창천과 운문천의 유입부 지점이 합류부나 취수탑 부근보다 출현종 수가 많았다. 식물플랑크톤 현존량은 동창천 유입부 지점에서 가장 높은 현존량을 나타내었으며, 계절별로는 봄철에 가장 높은 현존량을 나타내었다. 식물플랑크톤 현존량의 강별 구성은 가을철에는 와편모조류가 가장 높은 구성비를 차지한 반면 나머지 계절 동안에는 규조류가 가장 높은 구성비를 나타내었고, 남조류는 여름철에 비교적 높은 구성비를 나타내었다. 식물플랑크톤 군집의 우점종은 여름철에는 규조류Aulacoseira granulata가 우점종으로 나타났고, 가을철에는 와편모조류 Peirdinium voltzii, 겨울과 봄철에는 규조류 Asterionella formosa가 우점종으로 조사되었다. 운문댐의 식물플랑크톤 군집의 종풍부도와 종다양성지수는 가을철에 가장 높게 나타났으며, 우점도지수는 봄철에 가장 높게 나타났다.
