摘　　要：通过对大连-烟台海底光缆路由区海底土中的硫化物含量分布规律的研究,发现路由区表层海底土中硫化物含量最高为47.1×10-6,分布在路由的北端;最低含量在检出限以下(即<0.5×10-6),分布在路由的中部和南部的大部分区域。1.0～1.5 m层海底土中硫化物含量均在检出线以下。说明表层海底土中硫化物的含量远大于1.0～1.5 m层海底土中硫化物含量。对其原因进行分析,发现该海底土中硫化物含量的分布规律主要受海底土类型和水动力特征的影响和制约。Distribution regularity of sulfide in the seabed soil of the Dalian-Yantai submarine cable route area was researched in this paper. The conclusions are that sulfide content in the superficial seabed soils is the highest （47.1 × 10^-6 ） in the north section of the route area, and the lowest （ 〈0.5 × 10^-6 ） in the middle partial and south partial areas. The reason is the affection and restriction of seabed soil types and hydrodynamic force character. In 1.0 - 1.5 m seabed soils, sulfide content is lower than 0.5 - 10.6. The results showed that the sulfide content in the superficial seabed soils is far higher than in the 1.0 - 1.5 m seabed soils. By analyzing, it is a seabed soil type and the hydrodynamic conditions impact on the sulfide content distribution.
