中文摘要：

在河口浇的 Daya 海湾， Qingdao 海岸， Jiaozhou 海湾，华南海和 Huanghe 的铜 complexing 配合体集中被阳极的 strippingvoltammetry 技术决定。有另外的参数的分发整齐和关系被讨论。结果如下：南方 ChinaSea 的铜 complexing 配合体集中比另外的海区域的那些高一些，并且他们是比海洋的那些显然高级的。与在海面的表面下的层(SSL ) 相比，微层铜 complexing 配合体集中显示出丰富现象，机制类似于溶解有机物。南方 ChinaSea 的金属 complexing 配合体集中侧面证明在海面的价值最高，然后，它与深度 accruing 减少了，并且更高的价值出现在底部。铜 complexing 配合体集中比镉和铅的那些高。在每个海区域的 Ligands 展出了一个复杂性质。简言之，中国的沿海的水里的铜 complexing 配合体集中的分发整齐与在世界上的另外的区域的一致。同时，在铜 complexing 配合体集中之间的积极关系和生物需氧量，化学需氧量，溶解的器官的碳，和粘性清楚地被发现。

英文摘要：

Copper complexing ligand concentrations in the Daya Bay, Qingdao coast, Jiaozhou Bay, South China Sea and Huanghe Estuary waters were determined by the anodic stripping voltammetry technique. The distribution regularity and the relationship with other parameters were discussed. The results were as follows： Copper complexing ligand concentrations of the South China Sea were a little higher than those of other sea areas, and they were apparently higher than those of the ocean. Compared with the subsurface layer （SSL） in the sea surface microlayer copper complexing ligand concentrations showed an enrichment phenomenon, of which the mechanism is similar to dissolved organic matter. The metal complexing ligand concentration profiles of the South China Sea showed that the value in the sea surface was the highest, then it decreased with depth accruing, and a higher value appeared at the bottom. Copper complex- ing ligand concentrations were higher than those of cadmium and lead. Ligands in each sea area exhibited a complicated property. In short, the distribution regularity of copper complexing ligand concentrations in China＇s coastal waters was consistent with that of other regions in the world. Meanwhile, the positive relationship between the copper complexing ligand concentrations and biological oxygen demand, chemical oxygen demand, dissolved organic carbon, and viscosity were found clearly.
