利用南海北部的海上综合观测平台，开展了基于涡相关方法的海-气界面CO2通量的长期观测，得到了2010年9月至2012年9月近2年的海-气界面CO2通量数据，结果分析表明，观测平台附近海域全年表现为一个碳汇，年平均值为-0.088 mg m-2s-1，存在明显的季节变化规律，秋冬季节海洋表现为一个强碳汇，春季海洋依然是一个碳汇，但强度明显减弱，而夏季海洋呈现不稳定的源汇变化特征；从日周期特征上看，夜间通量强度较强，白天减弱；进一步的分析表明，海上风和大气稳定性对海-气界面CO2通量有明显的贡献。

A long-term observation of air-sea CO2 flux was performed on a fixed platform in the northern South China Sea, using eddy covariance method. The measurements cover a period of 2 years ranging from September, 2010 to September, 2012. The results demonstrate that the study region is a sink for CO2, with an averaged CO2 flux of-0.088 mg?m-2?s-1. A clear seasonal variability of air-sea CO2 flux is revealed. The sea is a strong sink for CO2 in autumn and winter, while turns to be a much weaker sink in spring, and in summer the air-sea CO2 flux is rather weak and the sea characterizes either a sink or a source. A diurnal cycle is observed, with a higher magnitude of CO2 flux at night. It has been found that the air-sea CO2 flux has a clear correlation with the surface wind and air instability.
