| 摘 要： | 卫星对地观测技术是全球范围内实时监测孕震区地震活动和震后应急救援的有力工具。过去的几十年里，不同种类的卫星观测数据被应用于地震遥感异常探测领域中，并逐渐开展了从单个震例分析，到普遍规律探索，再到内部机理研究的多方面探讨。但由于地球系统的复杂性和孕震过程的不确定性，地震遥感异常研究仍充满困难和挑战。本文利用文献计量分析方法，探究了现今国内外地震遥感异常研究的关注热点和趋势方向，认为目前对于地震遥感异常的研究已由单一参量发展为多参量联合分析阶段；通过3个前沿研究案例分析了常用的综合分析参量与异常分析方法，以及多参量之间的时空同步性关系，表明多参量遥感异常的结合研究和交叉验证是地震遥感异常研究中的重要手段，可以在未来地震前兆研究中发挥重要作用。

| Abstract: | Satellite Earth observation technology is a powerful tool for real-time monitoring of earthquake activity in seismogenic areas and emergency rescue after earthquakes on a global scale. In the past few decades, varieties of satellite observation data have been used in the field of seismic remote sensing anomaly detection. And multi-faceted discussion from analysis of individual earthquake cases to the exploration of universal laws and the study of internal mechanisms have been carried out. However, due to the complexity of the Earth system and the uncertainty of the seismic preparation process, seismic remote sensing anomaly research is still full of difficulties and challenges. This paper uses the bibliometric analysis method to explore the hotspots and directions of current seismic remote sensing anomaly research all around the world. It is believed that the research on seismic remote sensing anomalies has developed from single anomaly parameter analysis to multi-anomaly parameters comprehensive analysis stage currently. By three frontier research cases to analyze commonly used comprehensive analysis parameters and methods, as well as the spatiotemporal synchronization relationship between multiple parameters, it indicates that the combined research and cross-validation of multi-parameter remote sensing anomalies is an important method in seismic remote sensing anomaly research, which can play a significant role in the study of earthquake precursors in the future. |
