摘　　要：底质中的硫化物含量是一项重要的环境指标。本文对灵山卫附近海域50个底质样品进行了硫化物分析。硫化物的最高含量为78.42mg/kg,最低含量在方法的检出限(0.5mg/kg)以下,平均含量为5.29mg/kg。该海域大部分硫化物的含量在5.0mg/kg以下。硫化物的含量较低,表明该海域的底质环境为氧化环境。硫化物的含量主要受物质来源的影响,也与水动力条件和水深等因素有关。The sulfide content of bottom sediments is one of the most important environmental indexes. 50 samples of the surface sediment from the Lingshanwei sea area have been subjected to sulfide analysis. The results show that the highest content of sulfides is 78.42mg/kg, and the lowest one is below the limit of detection of the determining method (0.5mg/kg), with an average content of 5.29mg/kg, Generally, the sulfide content of the sediments analyzied is below 0.5mg/kg in most parts of the area studied, which could be possibly indicate that the bottom environment of the area is oxic. The sulfide content of the sediment is chiefly affected by material sources and also related to other factors such as water dynamic conditions, water depth and the like.
