| 摘 要： | 通过采用不同方法对东沙底质沉积物进行了土粒相对密度分析前处理，以探讨东沙底质沉积物中可溶盐、碳酸盐和有机质对其土粒相对密度的影响。结果表明，去除盐、碳酸盐和有机质后，东沙底质沉积物土粒相对密度明显降低，其中可溶盐对其土粒相对密度的影响最大。有机质含量的变化与东沙底质沉积物土粒相对密度变化的关系较大，呈负相关；而可溶盐和碳酸盐含量的变化与东沙底质沉积物土粒相对密度变化的关系则很小。

| Abstract: | We used different methods to pre-treat specific gravity of seafloor bottom sediments in the Dongsha Islands in order to study influence of salt, carbonate and organic matter in the sediments on the specific gravity. The study results show that after salt, carbonate and organic matter being removed, the specific gravity evidently drops, and among them, salt has the largest influence on the specific gravity. Changes of organic matter content are negatively correlated with the specific gravity, while carbonate content shows little relation to the changes of specific gravity of the sediments. |
