地震活动热红外异常的影响因素分析
|
摘要
对地表热红外辐射的基础理论和各类地物的热红外辐射特性进行了简略介绍;对地形地貌、地物类型和气象等非震因素对地表热红外辐射的影响及地表热红外亮温的时空变化特征进行了详细的分析;对各类非震因素的去除方法进行了探讨。初步认为,充分研究活动构造区带在各类非震因素影响下的热红外影像特征,掌握无震条件下的红外亮温时空演化过程,建立红外亮温变化的基准模型及各类非震因素的扣除模型,将有可能较好地排除非震因素的影响,检测出与地震活动有关的热异常。
The basic principles of thermal infrared radiation and the thermal radiation properties of different objects on the earth surface are introduced, and the influence factors to the earth surface's thermal radiation and the temporal-spatial varying characteristics of the earth surface's brightness temperature are analyzed, finally some methods are discussed for eliminating non-earthquake influence factors such as landform, the earth surface's objects and weather and to detect the heat variation related to earthquakes or fault activities. As a result, it would be necessary and effective for getting rid of the influence of non-earthquake factors and detecting the seismically active heat anomaly to fully study the thermal image features, understand the temporal-spatial evolvement course of brightness temperature in common situation without earthquakes, and build the background model of infrared brightness temperature and the deducting model of non-earthquake influence factors.
