海口湾海域水质石油类分布与评价

Distribution and Assessment of Petroleum Hydrocarbons in Sea Water of Haikou Bay

2018年10月对海口湾20个站位表层海水水质石油含量进行调查,探讨其分布趋势,并对石油含量进行单因子指数评价。结果表明,该海区表层海水水质石油的含量范围0.005～0.063 mg/L,平均值0.021 mg/L,石油含量分布呈现湾西部较低、东部较高的格局,除了17号以及18号站,其他站位的海水石油类含量均满足所在海洋功能区的要求。

Based on the investigation of petroleum hydrocarbons content in surface seawater of 20 stations in Haikou Bay in October,2018,the distribution trend of petroleum hydrocarbons content was discussed,and the petroleum hydrocarbons content was evaluated by single factor index.The results show that the petroleum hydrocarbons of surface seawater in this area ranges from 0.005 mg/L to 0.063 mg/L,with an average of 0.021 mg/L.The distribution of petroleum hydrocarbons was lower in the western part and higher in the eastern part.Except that the petroleum hydrocarbons of site 17 and site 18 does not conform to the functional zoning,the sea water quality of other stations conform the marine environmental requirements of the functional zoning.
