| 摘 要： | 本文综合阐述了国内外红外背景场的研究进展，进而基于2010—2013年FY-2E卫星热红外亮温数据构建了首都圈和甘青川交界地区的亮温背景场，并对其时空演化特征予以分析. 研究结果表明，红外亮温背景场时间上主要受季节变化影响，空间上主要受地形影响，为地震热异常的判定和识别提供了研究基础和依据.

| Abstract: | The construction and analysis of thermal infrared background field can effectively improve the recognition of thermal anomaly before an earthquake. This paper comprehensively discusses the research progress of thermal infrared background field，and then uses China’s FY-2E satellite thermal infrared brightness temperature (TBB) data of 2010—2013 to construct the TBB background field of the Capital region and Gansu-Sichuan-Qinghai border region，and the spatio-temporal evolution characteristics of TBB background fields for the two regions are analyzed. The results show that，TBB background field is mainly affected by seasonal variation in time and by terrain in space. The results provide research foundation and basis for the judgement and identification of thermal anomaly for earthquakes. |
