【 摘 要 】

This paper analyzed the influence of rainfall-runoff on chromium (Cr)in Jiaozhou Bay using investigation data in April, July and October 1982. Results showed that Cr was strongly influenced by rainfall-runoff in different seasons. The wet season had not come in April, and there was a sediment process in the coastal waters in the southwest of the bay, while in waters far away from the coastal waters in the southwest the influence of rainfall-runoff was little and Cr contents in waters was homogeneous. The wet season had been coming in July, and there was a strong sediment process in the coastal waters in the southwest of the bay where the accumulation in bottom waters had been abundant. The wet season had come to an end in October, and there was also a sedimentation process in the coastal waters in the southwest of the bay, while in waters far away from the coastal waters in the southwest the influence of rainfall-runoff was little and Cr contents in waters was homogeneous again.
