摘　　要：为了更加方便和准确地对实施灭火工程之后的乌达煤田火区变化情况进行监测,以覆盖乌达地区的Landsat-8卫星遥感影像为基础,采用普适性单通道算法对煤田地表温度开展了反演研究,通过设定一定的阈值提取了煤田火区的空间分布,并利用相邻时间多幅影像提取的相似结果验证了煤田火区监测结果的可靠性,最后依据时间序列监测结果分析了2015—2017年煤田火区分布的变化情况。结果表明:提取出的煤田火区分布范围明显,且具有较高的可靠性;近3年乌达煤田煤火分布范围基本稳定,但有增大的趋势。In order to monitor the change of fire area in Wuda Coalfield after fire extinguishing project accurately and efficiently,the generalized single-channel algorithm is used to study the inversion of the surface temperature of Wuda Coalfield based on the Landsat-8 satellite remote sensing image covering the Wuda Area. Then the spatial distribution of coal fire in coalfield was extracted by setting a certain threshold, and its reliability was verified by the monitoring results with other images acquired in adjacent period. Finally, the distribution changes of coal fire from 2015 to 2017 was computed and given. The results indicate that extracted coal field fire area distribution range is obvious, and has a relative high reliability. And the distribution of coal fire region is basically stable during recent three years with just only a little increase.
