| 摘 要： | 利用2015年－2017年海洋环境监测数据，对辽东湾近岸海域沉积物石油类含量时空分布状况进行阐述，对其污染状况进行分析，对其污染来源进行讨论。研究结果表明，2015年－2017年辽东湾近岸海域沉积物石油类含量范围为1.5×10?6~2790.0×10?6，中位值为62.7×10?6。2015年－2017年辽东湾海洋功能区内沉积物石油类含量的总中位值大小顺序（前三位）为港口航运区>保留区>农渔业区。2015年－2017年辽东湾海洋功能区内沉积物石油类站位总超标率大小顺序（前四位）为工业与城镇用海区>保留区>农渔业区>港口航运区。石油类主要产生于港口航运区、工业与城镇用海区沿岸、保留区沿岸、农渔业区等生产活动较为频繁的区域。

| Abstract: | The temporal and spatial distribution of petroleum hydrocarbon of surface sediment of offshore marine areas in Liaodong Bay was examined based on the concentrations retrieved from marine environmental monitoring data from 2015 to 2017. The source and degree of pollution were also analyzed and discussed. The results show that the concentration of the petroleum hydrocarbon of surface sediment in Liaodong Bay from 2015 to 2017 was in the range of 1.5×10?6~2790.0×10?6, with a median value of 62.7×10?6. The total median values of petroleum hydrocarbon of surface sediment of marine functional zones in Liaodong Bay (the top three) were:port shipping area>reserve area> agricultural and fishery areas while the sequence of total over standard rate of petroleum hydrocarbon in sediment stations of marine functional zones in Liaodong Bay (the top four) was industrial and urban sea area> reserve area>agricultural and fishery areas> port shipping area from 2015 to 2017. The results indicate that the petroleum hydrocarbon mainly comes from areas with more frequent production activities, such as port and maritime areas, coastal areas for industrial and urban use, reservation areas, agricultural and fishery areas, etc. |
