海-气CO2通量的估算是碳循环研究的重要内容。随着卫星遥感技术的发展和外推算法的不断改进，基于海表层水CO2分压的调控影响因子，在不同的海域发展了不同参数的海表pCO2遥感外推算法，获得了区域性多时空尺度长时间序列的海域碳“源-汇”时空变化特征。本文针对单参数算法、双参数算法和多参数算法的发展过程和存在问题，综述了主要海区海-气CO2通量遥感外推算法的研究现状，并评述了在南大洋和北极海域利用遥感算法进行海-气CO2通量研究的应用。

The estimation of air-sea carbon flux is an important part of global carbon cycle research.Extrapolation meth-ods represent a new approach to applying remote sensing technology to estimate regional-scale air-sea CO2 flux based on analysis of sea surface pCO2 and its dominant controlling factors.Data on regional-scale temporal and spa-tial distribution of sea surface pCO2 and patterns of carbon sinks and sources over long time scales can be obtained using this new approach.In this study, an extrapolation method is developed using single regression, double regres-sion, and multiple regression, and the successful application of the method in the open ocean and coastal regions is demonstrated.The application of the method in the Southern Ocean and Arctic Ocean and implications for the fu-ture are also discussed.
