| 摘 要： | 电离层探测是近年来发展比较迅速的地震电磁监测手段之一，为地震短临监测预测提供了新的技术思路和方法。本文回顾总结了21世纪以来基于地震电离层异常研究发展而来的多种圈层耦合机制，主要介绍了3类可实现数值模拟计算的耦合理论模型，包括附加直流电场模型、声重波和电磁波传播模型，并通过与实测数据对比分析了现有模型的矛盾和不足。最后综合现有观测系统，探讨了未来地震电离层耦合机理发展的主要思路和方向。

| Abstract: | The seismo-ionospheric monitoring technology has been quickly developed in recent years, which provides new ideas and techniques for short-term and imminent earthquake prediction. The multi mechanisms about sphere coupling processes related to earthquakes are reviewed and summarized since this century. Three channels with realized digital model are introduced, including overlapped DC electric field model, acoustic gravity wave and electromagnetic wave propagation model. Compared with the actual observations, the contradiction and deficiency in the models are analyzed. Finally, based on the existing observation systems, the main ideas and research directions in the seismo-ionospheric coupling mechanism in the future are discussed. |
