摘要：Using investigation on Cadmium (Cd) in surfac and bottom waters in this bay during 1984-1988, this paper analyzed the horizontal distributions of Cd, defined that different spatio-temporal status of the settlement processes. Results showed that Cd contents in bottom waters were relative high/low in case of Cd contents in surface waters were relative high/low, and diffference of Cd contents between surface and bottom waters were also relative high/low in case of the Cd contents in surface waters were relative high/low. The diffference of Cd contents between surface and bottom waters were relative low in general. These indicated the settlement processes of Cd from surface waters to bottom waters were very rapid. There were three different status along with the time axis, as well as three different status along with the space axis. Taking time axis as the X-axis and space axis as the Y-axis, the blok diagram model of the nine spatio-temporal status of the vertical migration processes were established. Furthermore, the paper revealed the features of the settlement processes.
