This paper analyzed the horizontal distributions and the trends of Cu contents in surface and bottom waters in Jiaozhou Bay during 1982-1985 in Shandong Province of China. Based on this analysis, this paper established block diagram models for high sedimentation process. The distribution trends of Cu contents in surface and bottom waters could be determined, and the high sedimentation locations could be defined. In according to the block diagram models, the transport path and the remaining trace of the substance contents could be defined, and the horizontal distribution trends of the substance contents could be predicted.

This paper analyzed the horizontal distributions and the trends of Cu contents in surface and bottom waters in Jiaozhou Bay during 1982-1985 in Shandong Province of China, and the mechanism of transport trend in waters were revealed based on this analysis. Results showed that along with the directions of the input sources, the substance contents in surface waters were decreasing, as well as in bottom waters. The substance contents were settling rapidly, and were accumulating in bottom. The directions of the source inputs determined the horizontal distribution trends in both surface and bottom waters, while the substance contents in the source inputs determined the high sedimentation regions of substance contents.

This paper analyzed the sources and migration paths of Petroleum hydrocarbon (PHC) in Jiaozhou Bay in 1987. Results showed that PHC contents in May, July and November 1987 in surface waters in Jiaozhou Bay were 0.014-0.060 mg L-1 , 0.016-0.066 mg L-1 and 0.030-0.091 mg L-1 , respectively. The pollution levels of PHC in this bay were still slight in 1987. The major PHC sources in Jiaozhou Bay in 1987 were river flow and oil port, whose source strengths were 0.066 mg L-1 and 0.060-0.091 mg L-1 , respectively. The migration paths of PHC from different sources were also different since the source strengths and geographic locations of these sources were different. In general, different countermeasures should be provided to different sources of PHC.
