摘　　要：通过总结海洋环境水下电磁场源的产生机理、基本特性、频带幅值以及观测方法,确定了不同海域普遍存在、影响程度较大并且规律性较强的场源。最终给出具有重要研究价值的典型场源,即海洋大地电磁场、海浪感应电磁场、海流感应电磁场和工频电磁场。In this paper, field sources with universal existence, large influence and strong regularity at different sea areas were determined through summarizing the mechanism of production, essential characteristics, frequency band, amplitude and observation method of underwater electromagnetic field in ocean environment. Finally, typical filed sources with the most important research value were revealed, including marine magnetotelluric field, wave induction electromagnetic field, current induction electromagnetic field and power frequency electromagnetic field.
