摘要

根据遥感物理基础，提出了应用ＤＴＭ计算出地表的太阳辐射强度，并以此为依据校正ＴＭ第６波段的象元值，消除地形的影响，突出由煤层自燃引起的地表热异常，为灭火工程及火区动态监测提供信息和指导。文中选择了新疆准南煤田的硫磺沟火区为试验区，展示了研究的成果。

Abstract

Coal fire is a commonly existed disaster in coal fields of northen China

it burnt huge amount of coal resource. Firefighting is a long-term and tough job.Thermal infrared images of TM band 6 show us temperature information

which depends on solar radiance and ground heat. Based on remote sensing principle

this paper focuses on using DTM to improve the accuracy of detecting coal fires with thermal infrared images. On the resultant image thermal anomaly caused by coal fire is much clear

this is helpful for firefighting and dynamic monitoring. Junnan coal field was selected as a test area. Several pictures were displayed for the result.
