本文对99个表层样经Q型因子分析,求得四个浮游有孔虫组合:热带-亚热带组合、高盐组合、过渡组合和抗溶组合,其中热带-亚热带组合为优势组合,其方差贡献为74.96％,该组合的发育状况反映了西太平洋热带海水对南海的影响程度,这四个组合在南海反映了不同因素对浮游有孔虫组合的影响,其中热带-亚热带组合为温度,高盐组合为盐度,过渡组合为温度,抗溶组合为水深。
In this paper, 99 surface samples were analyzed by Q-factor, and four planktonic foraminiferal assemblages were obtained: tropical-subtropical, high salt, transitional and anti-soluble combinations with the tropical-subtropical combination being the dominant combination whose variance contribution And 74.96% respectively. The development of this assemblage reflects the degree of influence of tropical seawater on the South China Sea in the western Pacific. The four combinations reflect the impact of different factors on the planktonic foraminiferal assemblage in the South China Sea. The tropical-subtropical combination is characterized by temperature, high salt The combination is salinity, the transition combination is temperature, and the anti-soluble combination is water depth.
