Abstract: With the use of the Landsat8 data, the authors attempt to analyze the change of the surface temperature of Daquanhu coal fire which is based on the inversing of surface temperature of this coal fire.Result show that the max temperature, the average temperature and the threshold temperature have the same trend of change.The max temperature appears in 2016.The change trend of abnormal temperature area is mainly U-shaped, and the largest area was in 2013.The abnormal temperature area presents a discontinuous distribution with the change of areas.
