| 摘 要： | 根据2006年6～7月对黄东海大面调查的资料,分析研究了黄东海颗粒有机碳(particulate organic carbon,POC)的浓度和分布特征。结果表明,夏季黄东海POC的浓度范围是6.07～2 204.17μg.L-1,平均浓度为147.15μg.L-1。POC整体上呈现近岸浓度较高、远岸浓度较低,北部浓度较高,南部浓较低的分布特点;在长江口外及浙江近岸海区存在POC的高值区,特别是长江口外,表层和底层POC浓度很高,这主要是受到长江陆源输入的重要影响。在垂直分布上,南黄海区POC的浓度分布整体上呈现上层水体浓度较低,下层水体浓度较高的特点,这主要是受底质再悬浮的影响。而东海区呈现近岸POC浓度较高,离岸POC浓度较低的特点,这主要是受长江冲淡水输入的影响。

| Abstract: | Based on the data from cruises that carried out in the Yellow Sea and East China Sea from June to July,2006,the concentration and distribution of particulate organic carbon(POC) were analyzed.The result showed that the concentration of POC in the Yellow Sea and East China Sea ranged from 6.07 to 2204.17 μg·L-1 in summer and the average content was 147.15 μg·L-1.In horizontal distribution,the highest POC content in the coastal zones and it tend to decrease toward the far shore,the highest concentration of POC appeared in the north in the Yellow Sea and East China Sea while the value was lower in the south on the whole.There were high value-zone of POC concentration in the Yangtze River estuary and coastal water areas of Zhejiang province.In the Yangtze River estuary both the surface layer and bottom layer POC high content occurred,which were mainly affected by the Yangtze River diluted water.In vertical distribution,concentration of POC in the South Yellow Sea was low in the upper water while high in the lower water as a whole,which was mainly from the effects of sediment resuspension.However,POC concentration in the East China Sea was higher in coastal waters and low offshore,this was mainly under the influence of the Yangtze River diluted water input. |
