| 摘 要： | 依据渤海湾及其邻近海域163个表层沉积物样品的总有机碳(TOC)和总氮(TN)的分析数据,探讨了渤海表层沉积物TOC的空间分布与物源贡献.结果显示,渤海湾TOC呈现南高北低的空间分布特征,TOC与粒度有一定的相关性且TOC高含量区与泥质区相吻合,表明TOC分布在一定程度上受控于沉积动力环境.TOC和TN之间显著相关,在...

| Abstract: | Organic carbon and total nitrogen were analyzed for the 163 surface sediment samples collected from the Bohai Bay during the summer of 2006.In this paper,we mainly discuss the distribution of total organic carbon(TOC) and its contributors.Results show that the concentrations of TOC are high in the southern and low in the northern part of the study area.There is a positive correlation between TOC and median diameter of grain sizes of sediments,indicating that the distribution of TOC is controlled by depositi... |
