湄洲湾海域表层沉积物石油类分布特征

通过2008年5月对湄洲湾的表层沉积物中石油类含量的调查，对石油类在湄洲湾表层沉积物中的分布特征进行探讨。结果表明：表层沉积物中的石油类含量范围为20×10^-6～87×10^-6，平均值为40×10^-6，其含量分布从湾内到湾外呈下降趋势，水平方向也呈现西高东低的趋势，主要受陆源输入，水文动力因素和沉积物类型的影响。

Study on the Distributed Characteristics of Petroleum Hydrocarbon in Surface Sediment in Meizhou Bay

Petroleum hydrocarbon in surface sediment of Meizhou bay was measured in May of 2008. The distribution of petroleum hydrocarbon would be discussed in this paper. The results showed that the petroleum hydrocarbon content in surface sediment ranged from 20 ×10^-6 -87×10^-6 and the average was 40×10^-6. The content decreased gradually from north to south and from west to east. Though many factors could affect on the petroleum hydrocarbon in surface sediment of Meizhou bay, land - based runoff, hydro - dynamics factor and sedimentary type were major factors.
