| 摘要: |
| 为了研究钦州湾外湾海域浮游植物群落分布特征，于2021年1月(冬季)在该海域进行综合调查。研究应用高效液相色谱(HPLC)技术分析表层水的光合色素组成，进而使用CHEMTAX软件估算浮游植物的群落结构。调查结果表明，调查海域浮游植物的优势类群为硅藻，其后依次为隐藻和青绿藻，它们分别占据了浮游植物总生物量的62.29%、20.25%和9.77%。从粒级结构上看，小型浮游植物(主要为硅藻)的贡献率为39.25%，粒径小于20 μm的浮游植物贡献率为60.75%；硅藻的细胞粒径范围较广，而隐藻、甲藻和蓝藻的细胞粒径多在20 μm以下。在空间分布上，硅藻的生物量由近岸向远岸海域逐渐升高，隐藻和青绿藻的分布则相反；微型和微微型浮游植物在盐度低、营养盐含量较高的近岸区占优势，小型浮游植物的生物量则由近岸向高盐度、低营养盐的远岸海域逐渐增大。浮游植物类群的空间分布特征与核电站温排水、盐度、潮流、营养盐以及贝类养殖等环境因素关系密切。 |

| Abstract: |
| In order to study the distribution characteristics of phytoplankton community in the outer bay of Qinzhou Bay,a comprehensive survey was conducted in this area in January 2021 (winter).The composition of photosynthetic pigments in surface water was analyzed by High Performance Liquid Chromatography (HPLC),and the community structure of phytoplankton was estimated by CHEMTAX software.The results showed that the dominant group of phytoplankton was diatoms,followed by cryptophytes and prasinophytes,which accounted for 62.29%,20.25% and 9.77% of the total biomass of phytoplankton,respectively.In terms of particle size structure,the contribution rate of micro-phytoplankton (mainly diatoms) was 39.25%,and the contribution rate of phytoplankton with particle size less than 20 μm was 60.75%.The cell size range of diatoms was wide,while the cell size of cryptophytes,dinoflagellates and cyanobacteria was mostly below 20 μm.In terms of spatial distribution,the biomass of diatoms gradually increased from inshore to offshore areas,while the distribution of cryptophytes and cyanobacteria was opposite.Micro-and pico-phytoplankton were dominant in coastal areas with low salinity and high nutrient content.The biomass of small phytoplankton gradually increased from the coastal area to the offshore area with high salinity and low nutrient content.The spatial distribution characteristics of phytoplankton groups are closely related to environmental factors such as thermal discharge,salinity,tidal current,nutrients and shellfish culture. |
