英文摘要	This paper quantified the spatial-temporal migration processes of Cadmium (Cd) in Jiaozhou Bay in 1989. Results showed that the horizontal losses of Cd in surface and waters in April 1989 were 37.50% and 16.66%, respectively. The vertical dilution of Cd in the bay center in July 1989 was relatively high i.e. 50.00%. Cd contents in both the surface and bottom waters were decreasing in a certain degree during the horizontal and vertical migration processes. No matter whether it is from the bay center to the bay mouth, or from the bay mouth to the bay centers, Cd contents were decreasing in a certain degree. In case of the rate of loss of Cd in the surface water was relatively high, and the rate of loss of Cd in the bottom water would also be relatively high and vice versa. In April 1989, Cd in the surface waters could be transported to the bottom of sea rapidly and continuously, and the vertical loss of Cd could be as high as 1/3 during the vertical migration process. Furthermore, in July 1989, the vertical loss of Cd was as high as 50.00%, where the vertical losses in Jiaozhou Bay were increasing from 1/3 in April to 1/2 in July. The vertical losses in Jiaozhou Bay were increasing along with an increase in the content of Cd in the surface waters.
