【 摘 要 】

Using investigation on Cadmium (Cd) in surface and bottom waters in this bay during 1984-1986, this paper analyzed the horizontal distributions, identified the different distribution trends, and provided block diagram model to demonstrate the migration processes of Cd. Results showed that the horizontal distriution trends of Cd in bay waters were determined by the source inputs, the transport paths and the horizontal and vertical water's effects. This indicated that the distribution trends of Cd contents in surface and botom waters would be consistent even if the source strengths were different. There were three different horizontal distribution trends, namely "Yang's horizontal distribution trends". The horizontal migration processes were showing three different status as 1) the settlement of Cd had not been arrived at sea bottom, 2) the settlement of Cd had been arrived at sea bottom, and 3) the accumulation of Cd had been occurred at sea bottom. The path ways and remaining traces of Cd could be defined in according to "Yang's horizontal distribution trends".
