摘要

The paper analyses seasonal changes of spectral characteristics values of satellite remote sensing when the forest fire was happening during the season of forest fire prevention. Based on the seasonal change characteristics and spectral characters of polar satellite bands, the forest hotspot was identified by using several infrared bands, and based on the combination-spectral expression of mid-infrared and thermal-infrared channel, the spectral threshold would be established for monitoring forest fire in different forest growing season in subtropical monsoon zone.
