中文摘要：
依据2010年9月8日～9月22日对黄渤海调查所得的数据,分析了黄渤海溶解有机碳（dissolved organic carbon,DOC）的含量及平面分布特征,并对其影响因素进行了初步探讨。结果表明,秋季,渤海和黄海DOC含量范围分别为1.51～3.00 mg/L和0.96～2.51 mg/L,平均值分别为（2.19±0.28）mg/L和（1.58±0.29）mg/L。DOC含量在不同海区表现为渤海〉黄海。平面分布上,秋季DOC的平面分布呈现北高南低,近岸高、远海低的特征。秋季渤海DOC高值主要集中在莱州湾中部,由于莱州湾中部DOC与叶绿素之间具有较好的正相关,推测该区域高的DOC可能受到浮游植物生长的影响。
英文摘要：
Based on the data from the cruise carried out in the Yellow Sea and Bohai Sea from September 8 to 22,2010,the concentration and horizontal distribution of DOC were studied.The possible influencing factors were also discussed in this paper.The results showed that the concentrations of DOC in the Yellow Sea and Bohai Sea ranged from 1.51 to 3.00 mg/L and 0.96 to 2.51 mg/L in autumn respectively.The average concentrations were（2.19±0.28） mg/L and（1.58±0.29） mg/L respectively.The concentration of DOC in Bohai Sea was higher than that in the Yellow Sea.The horizontal distribution of DOC in autumn showed that the concentration of DOC decreased from north to south in the researched area,and tended to decrease offshore.Due to the better pertinence between DOC and chlorophyll a,the high value of DOC was in the central section of Lai Zhou Bay in Bohai Sea in autumn,which was probably influenced by the growth of phytoplankton.
