Sediment samples from the marine systems along the coast of China, covering Yellow Sea, inner shelf of the East China Sea (ECS) and the South China Sea (SCS), were analyzed for n-alkanes and organic carbon. The concentrations of Σn-C(15-35) were 120-1680 ng g(-1) dry weight with an average of 560 ng g(-1). Short-chain n-alkanes (<C(21)) in Yellow Sea and the SCS were derived from mixed bacteria and planktonic sources, while those in the ECS inner shelf were mainly of planktonic sources. Long-chain n-alkanes (>C(21)) were mainly derived from terrestrial higher plants. Organic carbon deposited into Yellow Sea and Southeast Hainan within the SCS was mainly of terrestrial (13-110%; mean: 58%) and marine (48-110%; mean: 86%) sources, respectively. On the other hand, organic carbon accumulated in the SCS adjacent to the Pearl River Estuary was derived from both terrestrial and marine sources.
对中国沿海海洋系统的沉积物样本进行了分析，包括黄海、东海（ECS）内架和南海（SCS）。分析了正构烷烃和有机碳。Σn-C（15-35）的浓度为 120-1680ng/g 干重，平均值为 560ng/g。黄海和南海的短链正构烷烃（<C（21））来源于混合细菌和浮游生物源，而东海内架的则主要来自浮游生物源。长链正构烷烃（>C（21））主要来源于陆地高等植物。沉积在南海的海南岛东南部和黄海的有机碳主要来源于陆地（13-110%；平均值：58%）和海洋（48-110%；平均值：86%）。另一方面，在珠江口附近的南海中积累的有机碳则来自陆地和海洋的混合来源。
