摘要： 海气碳通量的估算是碳循环研究的重要内容。在估算区域性海气碳通量的研究上，随着卫星遥感技术的发展和外推算法的不断改进，在不同的海域基于海表层水CO2分压的调控影响因子，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”时空变化规律。本文通过对单参数算法、双参数算法和多参数算法的发展过程和存在问题，综述了全球海洋区域性海气碳通量遥感外推算法的研究现状， 并评述了在南大洋和北冰洋利用遥感算法进行海气CO2通量研究以及应用前景。

Abstract: The estimation of air-sea carbon flux is the important part of global carbon cycle research. With the development of remote sensing technology and the progress in extrapolation method, a new approach applying remote sensing technology to estimate regional-scale air-sea CO2 flux based on the analyses of sea surface pCO2 and its dominant controlling factors. A regional-scale temporal and spatial distribution of sea surface pCO2 and long time series patterns of carbon sink or source can be obtained by the new approach. In this study, we represent the development of the extrapolation method by single regression, double regressions and multiple regressions and the successful application in the open ocean and the coastal region. We also summary the application in the Southern Ocean and in the Arctic ocean and the implication in the future.
