空间对地观测研究是近年来国内外地震科学研究发展的重要方向。由于新的观测技术和理论的快速发展,地壳逸出氡和电离层异常耦合关系在地震前兆信息分析中有可能发挥重要作用。本文重点介绍了近年来国际上在强震地壳逸出氡和电离层异常耦合关系研究方面的主要进展,包括氡和电离层异常耦合关系的基本理论、观测依据和物理解释等,同时也介绍了在地震前兆研究中氡和电离层异常耦合关系的基本特点。研究认为,由于地面氡观测和卫星电离层观测均存在各自的优势和不足,因此利用空间对地观测技术来研究地壳逸出氡和电离层异常的耦合关系,可以全面提高对强震前兆异常信息的空间分析和可靠性判定能力,对全面发展地震监测预报技术具有重要的意义。
Space-to-Earth observation is an important direction for the development of seismic science both at home and abroad in recent years. Due to the rapid development of new observational techniques and theories, the anomalous coupling between radon and ionosphere in the crust may play an important role in earthquake precursor information analysis. In this paper, we mainly introduce the recent advances in the research on the anomalous coupling between radon and ionosphere in the crust of strong earthquakes in the world, including the basic theory, observation basis and physical explanation of the coupling relationship between radon and ionosphere anomalies, Basic Characteristics of Abnormal Coupling Relationship Between Radon and Ionosphere in Earthquake Precursor Study. The study shows that both ground-based radon observations and satellite ionosphere observations have their own advantages and disadvantages. Therefore, using the space-to-Earth observation technique to study the coupling relationship between the radon and ionospheric anomalies in the crust can comprehensively improve the information about precursor anomalies The spatial analysis and reliability of the ability to determine the overall development of earthquake monitoring and forecasting technology is of great significance.
