英文摘要 | Using investigation on Cd in surface waters in 1988 in Jiaozhou Bay, this paper analyzed the vertical changes of Cd contents in waters, defined the settlement processes of Cd contents at temporal and spatial scales. Results showed that in April 1988, in the outer side of the bay mouth, Cd contents in surface waters were higher than those in bottom waters, while in waters in the bay mouth Cd contents in surface waters were lower than in bottom waters. In July 1988, in the estuaries of the major inflow rivers in the northeast of the bay, the inner side of the bay mouth and the center of the bay, Cd contents in surface waters were higher than in bottom waters, while in waters in the southwest of the bay Cd contents in surface waters were lower than in bottom waters. During the settlement process of Cd, there were three time states at temporal scale, and three space states at spatial scale. Taking time as x-coordinate, and space as y-coordinate, a block diagram model was provided to describe the time and space states. In general, there were nine states during the actual settlement process. According to the spatial-temporal settlement process of Cd, the law of spatial-temporal settlement process was revealed, the changes of Cd contents in surface and bottom waters were determined by the strength of the source input and the distance of the transport path. |
