Based on the horizontal and vertical matter content changing models proposed by the author himself, this article calculates the horizontal loss amount, vertical disputed amount and vertical sediment amount, and determines the block diagram of horizontal and vertical Cd content changing model, applying the investigation matters about the Cd content of Jiaozhou Bay in May, August, and October, 1992. According to the calculation results of horizontal loss amount and horizontal increase amount of Cd content in the bottom layer and the vertical disputed amount and vertical sediment amount of Cd content in the surface and bottom layer, the author proposes the dynamic migration process of Cd content in Jiaozhou Bay, pinpoint the migration direction and route of Cd content from southeast waters to the center waters of the bay in May, August and October: sources→surface layer of southeast water→bottom layer of southeast water→bottom layer of center water→surface layer of center water, and get the dynamic changing process of absolute and relative migration amount of Cd content.
