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。
Based on the data from the survey of the Yellow Sea and the Bohai Sea from September 8 to September 22, 2010, the content and distribution of dissolved organic carbon (DOC) in the Yellow Sea and the Bohai Sea were analyzed and the influencing factors were discussed . The results showed that the DOC contents in autumn, Bohai and Yellow Sea ranged from 1.51 to 3.00 mg / L and from 0.96 to 2.51 mg / L, with mean values of (2.19 ± 0.28) mg / L and (1.58 ± 0.29) mg / L, respectively. DOC content in different sea areas showed the Bohai Sea> Yellow Sea. In the plane distribution, the plane distribution of DOC in autumn showed the features of north high south, high nearshore, and low distant sea. In the autumn Bohai Sea, DOC high values mainly concentrated in the central part of Laizhou Bay. Due to the good positive correlation between DOC and chlorophyll in the central part of Laizhou Bay, it is speculated that DOC in this area may be affected by phytoplankton growth.
