Abstract

Abstract

On the basis of data obtained during field observation in the Chengbei Oil Field and its adjacent sea areas in August 1996 and 2003,the concent ration of DO,COD,oil and heavy metals in the seawater,content of heavy metals,oil,organic matter and sulfide levels in the surface sediments,numbers of species,biomass and abundance of marine or ganisms are studied.Assessing the marine ecological environment,and analyzing the variation trend,the results indicate that petroleum exploration led to the decline of the ecological environmental quality in the area.It is found that the concent ration of oil in seaw ater rose obviously in the past years.The copper content is high enough to contaminate the surface sediments,while the oil concent ration increases continually.The bottom habitat is unhealthy and the benthos is contaminated by petroleum hydrocarbons.
