【 摘 要 】

This paper analyzed the spatial distribution characters of petroleum hydrocarbon (PHC) in Jiaozhou Bay using investigation data in surface waters in April, July and October in 1989. Results showed that PHC contents in surface waters in the whole year ranged from 0.020-0.474 mg L-1, and in April, July and October were 0.020-0.100 mg L-1, 0.010-0.474 mg L-1 and 0.006-0.082 mg L-1, respectively. River discharge and marine current were the two major PHC sources, whose source strengths were 0.010-0.474 mg L-1 and 0.082 mg L-1, respectively. In general, the source strengths of river discharge and marine current were moderate and slight in 1989. The input sources of PHC were changing with season, resulted in different spatial distribution characters in surface waters. By means of the influences of the major sources, the spatial distribution characters of PHC in surface waters in Jiaozhou Bay have three modes of semi-circle/parallel, semi-circle and parallel, respectively. These findings implied that the source control of anthropogenic sources is essential to pollution control and environmental remediation.
