摘要

摘要: 本文对黄、渤海表层沉积物中脂类化合物的组成进行了分析研究。结果表明，黄、渤海表层沉积物有机碳的含量为0.03%~1.02%，以黄河口含量最低，黄河口外和双台子河口外，以及北黄海和南黄海中部含量较高。有机质碳稳定同位素δ¹³C的分布为-21.55‰~-24.28‰，表征其陆海双重来源特征，并且海源特征由河口向海、由近岸向离岸逐渐增强。陆源脂类化合物以河口处略高，河道处略低，由河口向渤海中部和靠近渤海海峡方向迅速降低，表现出显著的河流输入特征；其形态组成由河道的游离态接近100%的绝对优势，迅速转变为渤海中部的以皂化结合态为主（大于50%），仅在渤海中部和渤海海峡附近存在小于5%的矿物结合态，转化程度较低。北黄海中部和南黄海中部泥质区的有机碳和陆源脂类化合物显著富集，但其对总有机碳的相对贡献较小；其中皂化结合态超过50%，矿物结合态小于10%，说明其具有中等偏高的转化程度。

Abstract: Surface sediments were analyzed in order to demonstrate the distribution and transformation of terrestrial organic matter in the Bohai Sea and Yellow Sea. Organic carbon ranged at 0.03%-1.02% in the surface sediments, in which low in the estuary of Yellow River and higher in areas off the estuaries of Yellow Sea and Shuangtaizi River, as well as higher in the central North Yellow Sea and central South Yellow Sea. δ¹³C of organic carbon ranged at -21.55‰ and -24.28‰, indicating both terrestrial and oceanic sources of organic carbon, and the oceanic source increased from near shore to off shore areas. Long chain fatty acids, long chain alcohols and terrestrial sterols existed higher in the estuaries, a little lower in the rivers, and rapidly decreased from estuary to the central Bohai Sea, suggesting significant riverine inputs. Meanwhile, the free lipids absolutely dominated by almost 100% in estuaries, and saponified lipids primarily contributed by >50% and a little mineral associated lipids accounted for <5% in the central Bohai Sea and Bohai Strait. The degradation of terrestrial lipids was significant from estuaries to central Bohai Sea and Bohai Strait, and the lipids were transformed in younger stage. Both organic carbon and terrestrial lipids highly accumulated in the fine-clay areas of central North Yellow Sea and central South Yellow Sea, but the terrestrial organic carbon contributed in minor ratio to total organic carbon. Saponified lipids accounted for >50% and mineral associated lipids <10% to total lipids, which implied a middle transformation of terrestrial organic carbon in fine-clay areas of central North Yellow Sea and central South Yellow Sea.
