According to the investigation data of Jiaozhou Bay in May, August and October of 1991, the Pb content and horizontal distribution at surface were studied. The results showed that the variation of Pb content was 4.09-31.66μg/L, which satisfies the Case II, III and IV Sea Water Quality Standard., showing that Jiaozhou Bay was mildly, moderately and severely polluted. Pb content in Jiaozhou Bay was mainly transported by ships and wharfs, overland runoffs and river flows, to be more specific, 12.74-31.66μg/L, 30.47μg/L and 11.46-16.04μg/L, respectively, showing the severe pollution. The three transport paths could be displayed by modelling diagram. The transport rule of matter content that the farther transport of matter content, the more loss in the way, proposed by the author was verified in this paper. Besides, the transport process of Pb content from the source to the ending was proposed by the author. Thus, human activities on the land and at sea caused the increasing Pb content transported to sea, and the space-time transport of Pb content caused the pollution to the environment and ecology.
