本文根据 1 994年 8月和 1 995年 2月在台湾海峡进行的综合调查资料 ,对海水TCO2 、PCO2 的分布特征及其与环境参数的关系进行了研究 ,并利用通量模式估算了海 气CO2 的净通量。结果显示 ,表层TCO2 、PCO2 的分布呈明显的季节变化特征 ,由于夏季受海峡暖流的影响 ,台湾海峡表层TCO2 、PCO2 普遍较高 ;冬季受浙闽沿岸水的影响 ,表层TCO2 、PCO2 呈海峡西部低 ,东部高的分布趋势。台湾海峡可视为大气CO2 的净汇区 ,CO2 由大气输入海洋的平均通量为 1 .45± 0 .5 1mol/ (m2 ·a)。
Based on the comprehensive survey data of TCO2 and PCO2 in seawater in August 1994 and February 1959, this paper studied the distribution characteristics of seawater TCO2 and PCO2 and their relationship with environmental parameters, and used the flux pattern to estimate the sea gas Net flux of CO2. The results showed that the distribution of TCO2 and PCO2 in the surface layer showed obvious seasonal variation. TCO2 and PCO2 in the surface of the Taiwan Strait were generally high due to the influence of the Channel’s warm current in summer. In the winter, the TCO2 and PCO2 of the surface were influenced by the coastal Zhejiang water, Low, high distribution trend in the east. The Taiwan Strait can be regarded as the net exchange area of atmospheric CO2, and the average flux of CO2 input into the ocean from the atmosphere is 1.45 ± 0.51mol / (m2 · a).
