Abstract：Multi-source satellite remote sensing data can provide rapid and accurate spatial information on blazes. According to the fire spot characteristics of sharply increasing in mid-infrared emissivity and brightness temperature, the authors analyzed the real-time dynamic monitoring of fire process, which happened in Jiuzhi of Guoluo Tibetan Autonomous Prefecture in Qinghai Province from March 18 to 19, 2016. Ten times of polar-orbit meteorological satellite data, especially NPP, were used to perform real-time monitoring, and GaoFen(GF) data were used to extracted the fire area. Finally, the fire distinguishing thresholds of Qinghai alpine grassland in spring were obtained. The results show that the fire-monitoring method could be applied to Qinghai, and that quick recognition threshold setting could meet the fast and effective requirements in daily real-time monitoring.
