| 于2016年7月和8月期间，在印度尼西亚蓝碧海峡和马来西亚吉兰丹河口区分别采集了水样用于分析浮游植物光合色素和群落组成的空间变化。利用高效液相色谱结合CHEMTAX软件检测浮游植物光合色素，确定叶绿素a生物量和群落组成。结果显示，蓝碧海峡表层海水叶绿素a浓度较低，在0.580~0.682μg/L之间，平均值为0.620±0.039 μg/L。然而，叶绿素a浓度在吉兰丹河口区表层海水波动较大，浓度在0.299~3.988μg/L之间，平均值为0.922±0.992 μg/L。在吉兰丹河口区，底层叶绿素a浓度明显高于表层，变动范围为0.704~2.352 μg/L，平均值1.493±0.571 μg/L。叶绿素b、玉米黄素和岩藻黄素是蓝碧海峡含量最丰富的三种色素。两个研究区域浮游植物群落组成存在着明显差别。在蓝碧海峡，青绿藻（26.48%±0.83%）和聚球藻（25.73%±4.13%）贡献了约50%的叶绿素a浓度，其次是硅藻（20.49%±2.34%）和定鞭藻-8型（15.13%±2.42%）。吉兰丹河口区表层海水主要以硅藻为优势（58.53%±18.44%），其次为聚球藻（27.27±14.84%）和青绿藻（7.00%±4.39%）；底层水体与表层近似，硅藻、聚球藻和青绿藻分别贡献了64.89%±15.29%，16.23%±9.98% and 8.91%±2.62%的叶绿素a浓度。浮游植物群落组成的这种差别表明，蓝碧海峡水体主要是寡营养盐的西太平洋水，可能主要受到上行效应的控制；而吉兰丹河口区由于营养盐的补充，硅藻优势度明显，可能主要受到微型浮游动物摄食微微型浮游植物的下行效应调控其浮游植物群落结构。 |

| Water samples were collected in order to study the spatial variation of photosynthetic pigments and phytoplankton community composition in the Lembeh Strait (Indonesia) and the Kelantan River Estuary (Malaysia) during July and August 2016, respectively. Phytoplankton photosynthetic pigments were detected using high performance liquid chromatography combining with the CHEMTAX software to confirm the Chl a biomass and community composition. The Chl a concentration was low at surface in the Lembeh Strait, which it was 0.580-0.682 μg/L, with the average (0.620±0.039) μg/L. Nevertheless, the Chl a concentration fluctuated violently at surface in the Kelantan River Estuary, in which the biomass was 0.299-3.988 μg/L, with the average (0.922±0.992) μg/L. The biomass at bottom water was higher than at surface in the Kelantan River Estuary, in which the Chl a concentration was 0.704-2.352 μg/L, with the average (1.493±0.571) μg/L. Chl b, zeaxanthin and fucoxanthin were three most abundant pigments in the Lembeh Strait. As a consequence, phytoplankton community composition was different in the two study areas. In the Lembeh Strait, prasinophytes (26.48%±0.83%) and Synechococcus (25.73%±4.13%) occupied ~50% of the Chl a biomass, followed by diatoms (20.49%±2.34%) and haptophytes T8 (15.13%±2.42%). At surface water in the Kelantan River Estuary, diatoms (58.53%±18.44%) dominated more than half of the phytoplankton biomass, followed by Synechococcus (27.27%±14.84%) and prasinophytes (7.00%±4.39%). It showed the similar status at the bottom water in the Kelantan River Estuary, where diatoms, Synechococcus and prasinophytes contributed 64.89%±15.29%, 16.23%±9.98% and 8.91%±2.62%, respectively. The different phytoplankton community composition between the two regions implied that the bottom up control affected the phytoplankton biomass in the Lembeh Strait where the oligotrophic water derived from the West Pacific Ocean. The terrigenous nutrients supplied the diatoms growing, and pico-phytoplankton was grazed through top down control in the Kelantan River Estuary. |
