| 中文摘要: |
| 本研究在南黄海四个季节的航次中（春季：2014年4月-5月； 秋天：2014年11月； 夏季：2015年8月-9月； 冬天：2016年1月）用双萃取法测定了生物硅的浓度。本研究还探究了四个季节时空变化的生物硅与叶绿素a含量的潜在相关性。海水中生物硅浓度存在显著的空间变异性，平均浓度最高在冬季，最低在春季。此外，我们还讨论了生物硅浓度与水文参数的关系，其中叶绿素啊与生物硅呈显著正相关，生物硅浓度与温度、硅酸盐、总无机氮、总无机磷浓度呈显著相关，说明生物硅的分布受温度和营养盐水平的影响。 |
| 英文摘要: |
| Concentrations of biogenic silica (BSi) in the southern Yellow Sea were determined during four cruises (spring: April–May 2014; autumn: November 2014; summer: August–September 2015; winter: January 2016). Samples of BSi were measured using the double extraction method. Seasonal and spatial variations of BSi and the potential correlation between chlorophyll a (Chl a) content and BSi in four seasons were measured in this study. Significant spatial variability was observed in seawater BSi concentrations. The average concentration of BSi was highest in winter and lowest in spring. Furthermore, the relationships between concentrations of BSi and hydrological parameters were also discussed. There was a significant positive correlation between Chl a and BSi. The concentrations of BSi showed significant relationships with temperature and the concentrations of silicates, total inorganic nitrogen and total inorganic phosphorus, indicating that distribution of BSi was affected by temperature and nutrient level. |
