Abstract

This study reported on the phytoplankton community and seasonal changes in the Seoul passage section and downstream in the Han River in 2012. Field samples were collected monthly from the upper (Paldang), middle (Cheongdam), and downstream(Seongsan) areas of the Seoul passage section. Water temperature, DO, pH, and conductivity were measured at each station. All environmental factors measured were recorded similarly at the three stations. The water temperature ranged from 2 to 30℃ and the dissolved oxygen ranged from 4.8 to 9.1 mg L-1, showing typical patterns of temperate regions. The phytoplankton cell concentrations ranged from 990 cells mL-1 (Paldang, December) to 2.9×104 cells mL-1 (Seongsan, March), and the chlorophyll-a content showed similar patterns to the cell numbers. The phytoplankton community was comprised of 75 genera and 95 species, including 37 diatoms, 29 Chlorophyta, 11 cyanobacteria, and two dinoflagellates. The number of species that appeared seasonally varied greatly, from nine species (Paldang, May) to 35 species (Cheongdam, December). Diatoms were the most dominant in all stations and seasons, except in summer. In contrast, chlorophytes and cyanobacteria showed sporadic high numbers in the summer and fall seasons. Four diatoms Stephanodiscus hantzschii f. tenuis, S. hantzschii, Fragilaria sp., and Aulacoseira spp., a chlorophyte Actinastrum hantzschii, and a cyanobacterium Microcystis sp. were each present in proportions greater than 10%. This study provides fundamental data from phytoplankton communities and environmental factors in the Han River for understanding water quality for long-term environmental monitoring.

한강은 서울 및 수도권 지역의 수자원으로 다양하게 이용되고 있어 지속적인 모니터링과 관리가 필요하다. 본 연구는 2012년도 한강 하류의 식물플랑크톤 군집구조와 계절별 변화를 규명하였다. 현장시료는 서울통과 구간의 상류(팔당대교), 중류(청담대교), 하류(성산대교)에서 월 1회 채집하였으며, 현장에서 수온, 용존산소, pH, 전도도를 측정하였다. 환경요인은 3개 정점에서 유사한 값으로 조사되었으며, 수온은 2~30℃ 범위이고 DO는 4.8~19.1 mg L-1로 온대지역의 전형적인 패턴을 보였다. 식물플랑크톤 수는 990 cells mL-1(팔당대교, 12월)~2.9×104 cells mL-1(성산, 3월)의 변동이었고, 엽록소는 0.6 ㎍ L-1(팔당대교, 12월)~10.3 ㎍ L-1(성산, 3월)로 세포수와 같은 양상을 보였다. 조사된 식물플랑크톤 군집은 규조류 37종, 녹조류 29종, 남조류 11종, 와편모조류 2종 등 총 75속 95종 이었다. 계절별 최저 출현은 9종(5월, 팔당대교)에서 최고 35종(12월, 청담)으로 변화폭이 컸다. 봄철(3~5월)에 평균 15종으로 적은 출현종수를 보였으며, 겨울철(12월)에 평균 27종으로 다른 계절보다는 다양한 출현 종수를 보였다. 규조류는 여름철을 제외하고 모든 정점과 계절에서 가장 우점하였다. 반면 녹조류와 남조류는 여름철과 가을철에 산발적으로 높은 우점률을 나타냈지만, 제 1우점군은 아니었다. 출현빈도 10% 이상 되는 종으로, 규조류는 Aulacoseira granulate, Cyclotella sp., Stephanodiscus hantzschii이며, 녹조류는 Actinastrum hantzschii이고, 남조류는 Microcystis sp.였다. 본 연구는 2012년 한강 하류의 식물플랑크톤 군집 변화 및 현존량, 우점종의 변화를 분석한 것으로, 향후 진행될 연구들과 환경변화에 따른 한강의 수질 및 식물플랑크톤 군집 변화를 이해하기 위한 좋은 기초 자료가 될 것이다.
