【 摘 要 】

In order to quantify the vertical transporting process of substance in marine bay waters, this paper established vertical content difference model, substance sedimentation amount model and substance accumulation amount model, and demonstrated the model performance based on the quantification of the vertical transporting process of Cu in Jiaozhou Bay, Shandong Province, China. Results showed that during 1982-1985 the absolute sedimentation amount and relative sedimentation amount of Cu were 0.29-18.23 μg L-1and 74.3%-96.2%, respectively, and for absolute accumulation amount and relative accumulation amount were 0.32-3.71 μg L-1and 76.1%-95.6%, respectively. By means of these models, the horizontal and vertical changes in surface and bottom waters and the change processes could be defined. This approach was straightforward yet was reliable enough to quantify the vertical transporting process of substance in marine bay.
