摘　　要：开展煤田火区现状调查,研究其对区域气候变化、生态响应系统的影响是评估自然灾害研究中的重要方面。选择新疆部分煤田火区进行了实地考察,开展了小尺度区域热辐射信息分析,依据现场实测资料分析,给出煤田热隐患状态的适度评定。分析结果表明:小尺度区域热辐射测量方法可用于判别已灭煤田火区的灭火效果分析及新形成火区探测;对于正在燃烧的煤田火区可判断火区的范围并为灭火提供参考依据。In this paper, Xinjiang＇ s coal field is selected as the investigation area. Through a series of field surveys in Xinjiang, we made the small-scale area analysis of coal field fire using the ground remote sensing technique, and presented the reasonable evaluation of thermal anomaly conditions of Xinjiang＇ s coal field arising from coal self-ignition fires. The results show that the method of small-scale area analysis is available for examining the extinguished actuality of coal fires and detecting fire spots. Therefore, for the selected fire-extinguished coal field in Xinjiang, the fire extinguishing effect was effectively analyzed by the means, and the new hidden thermal dangers were sought and diagnosed. For the coal field where the fire has not been extinguished, the utilization of this means approximately identified the severity and range of the fire area, and provided the quantitative and ground reference for extinguish engineering.
