摘要
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 data collected in the Taiwan Strait in August 1994 and February 1995,the distribution of T CO 2 and P CO 2 in seawater and their relationship with environmental factors are studied, and a net air sea flux of CO 2 is also estimated by using the flux model. The results show that T CO 2 and P CO 2 distributions in the surface water appear to be of seasonal variation. In summer, T CO 2 and P CO 2 in the surface water of the Taiwan Strait are generally high and appear to be controlled by the Strait warm current. In winter, T CO 2 and P CO 2 in the surface water are lower in the western than in the eastern Taiwan Strait owing to the southward spreading of the Zhe Min coastal water. The results also suggest that the Taiwan Strait serves as a net sink of atmospheric CO 2, the annual CO 2 flux from atmosphere into seawater is about 1.45±0.51mol/(m 2·a) .
