MODIS thermal infrared data of satellite and geostationary satellite thermal infrared brightness temperature data for 2006, Wen 'an 5.1 earthquake in Hebei province analysis method of temporal and spatial characteristics of two kinds of exceptions are used. Studies show that about a month before the earthquake, furnace heat index ratio high value exception and exception, and surface brightness temperature temperature abnormal area and the future of earthquakes that occur relatively close to the epicenter.%利用MODIS卫星热红外数据和静止卫星热红外遥感亮温资料,对2006年河北文安5.1级地震进行时间特征和空间特征两种异常分析方法.研究表明,地震前一个月左右,透热指数和异常比值同时出现高值异常,而地表的亮温增温异常区与未来发生的地震震中较为接近.
