dc.description.abstract We surveyed 23 sites of Jinhae Bay in spring and summer 2010 in order to study the correlation between the variation of environmental factors, including salinity, temperature, and nutrients and the characteristics of phytoplankton community structures in summer stratification. Phytoplankton biomass was high in the surface water in summer; however, it was very low in the bottom water. The results showed a negative correlation between chlorophyll a (chl. a) and nutrients (silicate, nitrate, nitrite, ammonium, and phosphate) or nutrients ratio in summer; however, there was mostly a positive correlation between chl. a and these nutrients in spring. This inconsistent correlation between spring and summer was attributed to the phytoplankton community, because a diverse phytoplankton community has different nutrient uptake abilities. In addition, the results of CCA (canonical correspondence analysis) showed a negative correlation between phosphate and dominant species, including Chaetoceros spp., Skeletonema costatum-like spp., and Pseudo-nitzschia delicatissima in summer, but a strong positive correlation between DIN (dissolved inorganic nitrogen) and the dominant species, including Cryptomonas spp. and Pseudo-nitzschia multistriata in spring. Consistently, the dominant algal species in summer showed a relatively smaller size cells compared with those in spring, suggested that it may have related with the low nutrient levels at surface layer due to strong stratified water column of summer. 2010년 진해만의 춘계와 하계를 중심으로 환경요인 변화와 식물플랑크톤의 군집구조의 상관관계에 대한 생태학적 연구를 수행하였다. 식물플랑크톤의 생물량과 환경요인과의 상관관계를 조사하기 위해 수행한 다중상관분석과 CCA (Canonical Correspondance Analysis) 결과, 하계에 우점한 Chaetoceros spp., Skeletonema costatumlike spp., Pseudo-nitzschia delicatissima는 생물량 변화에 영향을 미치는 주요 요인을 선정할 수는 없었다. 반면, 춘계의 Cryptomonas spp.와 Pseudo-nitzschia multistriata 는 질산염과의 양(+)의 상관관계(p<0.05)가 있을 것으로 판단되었다. 하계에 나타난 식물플랑크톤과 환경요인간의 유의한 양(+) 상관관계가 나타나지 않는 것은 강우에 의해 유입된 탁도 물질등에 의한 저층의 광합성 활성의 저하와 우점종의 구성과 생물량 차이에 의해 나타난 결과로 판단되었다. 또한 환경에 적응한 우점종의 분포특성은 진해만 광역해역을 부분적으로 구분할 수 있는 생물학적 요인으로 판단되었다. 결과적으로 식물플랑크톤과 환경요인과의 상관관계는 주요 우점종의 분포와 관련이 있었고, 특히 성층화된 하계에 우점한 식물플랑크톤 분포는 해역 구분에 중요한 인자로 활용 될 수 있었다. -
