【摘要】 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,使得高光谱在断层逸出气方面的应用在强震前兆信息分析中有可能发挥重要作用。本文简单介绍了断层气体地面监测和卫星遥感监测方面的应用现状,概述了高光谱遥感的原理、反演方案和方法等。笔者建议运用地面监测和高光谱遥感技术相结合的方法来监测强震前后活动断层逸出气的光谱变化,根据数学算法反演痕量气体组分浓度,最后,结合震例,探讨强震前后断层逸出气体异常变化量与强震的关系,提取断层气体各组分强震前兆信息。利用空间对地观测技术来研究断层逸出气,这样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。更多还原

【Abstract】 The research of space-to-ground observation has been an important development direction of seismological science at home and abroad in recent years.As a result of the rapid development of the new observation technology and theory,the study on hyper-spectra fault gas may play an important role in the analysis of earthquake precursor information for strong earthquake prediction.This paper describes briefly the status of application of ground and satellite monitoring,and summarizes the basic principle of hyper-spectra、inversion scheme and methods.The authors propose to use the combined ground techniques and hyper-spectra remote sensing technology to monitor the change of the active fault gas spectrum,use some inversion scheme to retrieve the concentration of trace gas,and combine earthquake case studies to probe into the relationship between the abnormity of fault gas and strong earthquake,and extract the precursory information of strong earthquakes.Utilizing the technology of space-to-ground observation to study fault gas for strong earthquake prediction,we can make overall improvement in spatial analysis of strong earthquake precursor information and the ability of judging the reliability,and it is of great significance for the comprehensive development of earthquake monitoring and forecasting.更多还原
