| 摘 要： | 断裂活动及孕震过程遥感热异常分析是对地观测及遥感应用的重要主题。本文从遥感数据应用、异常分析方法、异常认知理解3个方面系统回顾了近30年来该主题的研究概况与主要进展。具体包括:(1)关于遥感数据应用的红外亮温、微波亮温与长波辐射、对地观测同化数据及多源数据综合的4个方面;(2)关于地震遥感异常分析的目视解译定性分析、图像处理定量分析以及多参数时空关联分析的3个发展阶段;(3)关于地震遥感异常认知理解的地球放气、应力致热、地壳岩石电池转换、氡衰变潜热释放与多圈层耦合效应等理论学说。展望未来,提出了面向典型断裂活动区的遥感监测分析与异常识别、基于地球系统地震响应的遥感异常理解分析、空天地立体观测数据的时空关联分析等3个方面的攻关重点。

| Abstract: | Research to the remote sensed thermal abnormity with fault activity and seismogenic process is a vital topic of the Earth observation and remote sensing application. It is presented that a systematic review on the international researches on the topic during the past 30 years, in the respects of remote sensing data applications, anomaly analysis methods, and mechanism understanding. Firstly, the outlines of remote sensing data applications are given including infrared brightness temperature, microwave brightness temperature, outgoing longwave radiation, and assimilated data from multiple earth observations. Secondly, three development phases are summarized as qualitative analysis based on visual interpretation, quantitative analysis based on image processing, and multi-parameter spatio-temporal correlation analysis. Thirdly, the theoretical hypotheses presented for the mechanism understanding are introduced including earth degassing, stress-induced heat, crustal rock battery conversion, latent heat release due to radon decay as well as multi-spheres coupling effect. Finally, three key directions of future research on this topic are proposed:anomaly recognizing by remote sensing monitoring and data analysis for typical tectonic activity areas; anomaly mechanism understanding based on earthquake-related earth system responses; spatio-temporal correlation analysis of air-based, space-based and ground-based stereoscopic observations. |
