Popis: This paper collected the monitoring data of jinzhou sea in July 2008, September 2013 and September 2016, and analyzed in detail the variation trend of main pollutants (copper, lead, zinc, cadmium, mercury, arsenic, chromium, petroleum, sulfide, and organic carbon) in the sediment in Jinzhou sea. The results show that the regional Marine sediment environment before the implementation of reclamation (July 2008) is general, the regional Marine sediment environment during the implementation of reclamation (September 2013) and at the present stage (September 2016) is good, and the Marine sediment shows a good trend after the implementation of reclamation project. With the construction of the port area, large-scale dredging and backfilling, the contaminated surface layer sediments in the port area have been effectively removed and controlled.
