Abstract

海气CO2交换速率及通量的测定、估算是碳循环研究的重要内容。测定、估算海气CO2交换速率及通量有多种方法,但都有其局限性,准确定量海气碳通量的大小仍是碳循环研究的热点问题。当前应用最广泛的海气界面分压差法需要通过间接手段测定海气交换速率,交换速率和风速的关系基于经验公式,不确定性较大;而涡动相关法(eddy covariance/eddy correlation)是一种直接测量方法,理论上不需要任何经验参数,在近年来取得较大进展。综述了近年来国内外CO2海气交换速率及通量的测定、估算方法的研究进展,并对各种方法的原理、应用、优缺点进行了分析,着重介绍了涡动相关法测量CO2通量的原理、国内外研究现状、相对传统方法的优缺点以及发展前景等,对未来海气CO2交换速率及通量研究发展趋势和研究方法作了展望。
