摘　　要：围绕卫星红外异常预测地震方法的理论基础——临震红外异常的成因机制问题,简介前人基于实验的各种假说;结合红外遥感和地面观测实际进行验证和评述;从红外遥感理论依据——斯忒藩-玻耳兹曼定律出发加以分析,针对临震热红外异常出现时间的短暂性、范围的区域性、增幅的显著性等特点加以具体运用,从理论和实践的结合上,对红外异常的机理和红外遥感地震的方法,进行评述和展望。In this paper, the infrared anomaly related with impending earthquakes is analyzed as the basis for forecasting tectonic earthquakes by satellite thermal infrared anomaly. Many hypotheses based on experiments are reviewed, in the light of the infrared image analysis and ground observations. Their theoretical basis—— Stefan-Boltzmann law is applied to analyze the features of infrared anomaly, including the transient features in time, the regional features in space and the amplitude variation features in temperature. The paper focuses on the method of forecasting earthquake with satellite infrared remote sensing.
