【 摘 要 】

Using investigation data on Cu in April, July and October 1985, this paper researched the horizontal distributions of Cd in Jiaozhou Bay. Results showed that there were two major Cd sources, i.e., river flow and marine current, and the waters in Jiaozhou Bay could be divided into two classes. On one hand, in case of there was Cu input, Cu contents in waters was non-homogeneous. On the other hand, in case of there was little input, Cd contents in waters was homogeneous. Along with time, Cu contents in waters were undergoing process from non-homogeneous to homogeneous. This revealed that ocean has feature of homogeneous by means of tide and current. Ocean makes all of the substances in waters to be homogeneous, and make all of the substances in waters to diffuse in tends of homogeneous.
