| 摘 要： | 根据2008年泉州湾调查采集的样品，测定了泉州湾表层沉积物中常量元素和微量元素的含量，采用相关分析和因子分析进行元素组合特征的研究，讨论了它们的分布趋势、相互关系和主要来源，并探讨了其地球化学意义．元素相关分析结果表明，泉州湾表层沉积物常量元素与微量元素含量的相关性明显，表层沉积物成分以SiO2和Al2O3为主，其含量的最高值分别达78．39％和22．02％（m／m），其中SiO2与大部分常量元素、微量元素的含量呈负相关，而Fe2O3、MgO、Cu、Co、Ni、Rb、Pb与Al2O3含量之间呈强正相关．元素因子分析表明，泉州湾表层沉积物的物质来源主要有陆源和生物源2种，以陆源的为主．

| Abstract: | By carrying out the elemental analysis on the surface sediments of Quanzhou Bay,the combination characteristics of important elements and the significance of geochemistry are studied using correlation analysis and factor analysis.The result shows that the surface sediments from Quanzhou Bay have obvious correlation between main and trace element,and the SiO2 and Al2O3 are the most dominant components at the surface sediments with maximum value of 78.39% and 22.02%(m/m),respectively.SiO2 showed a negative co... |
