| 摘 要： | 根据2010 年2 月—2010 年3 月的调查数据, 探讨了冬季渤海海峡及其附近表层海水中溶解无机碳体系的分布特征。结果表明: 表层水体中TA、DIC 和HCO3- 的浓度分布总体上呈现出海峡西南部高东北部低的分布趋势。西南部出现的高值区, 与该区域靠近莱州湾, 受莱州湾水体污染影响有关。调查海域TA 与表层水的温度相关性明显, pH 与叶绿素的相关性较高。水温和Chl-a 浓度是影响水体中无机碳体系分布变化的重要因素。其中, 水温对HCO3- 的影响要明显强于DIC。海峡南北两侧水体交换的差异, 是导致海峡南部东西两端无机碳体系各参数监测数值的差异明显大于海峡北部的主要原因。

| Abstract: | The Bohai Strait is an important area due to its unique geographic feature. It plays an important role in the water cycle between the Bohai and North Yellow Sea. The distribution of dissolved inorganic carbon system in the surface layer of the Bohai Strait is studied in February to March, 2010. The results show that the concentration of TA, DIC and HCO3- were higher in southwest while lower in northeast. There is a significant negative correlation between the concentration of TA and surface temperature. While the concentration of Chl-a shows a significant positive correlation with pH. The distribution of inorganic carbon system was impacted by the temperature and the concentration of Chl-a. The effect by the surface temperature to the HCO3- is stronger than the DIC. The difference of inorganic carbon system between west and east at the south area was more than the north area. The main controlling factor is the difference of water change between north and south of the Bohai Strait. |
