| 摘 要： | 利用MODIS近红外、中红外及热红外的4个波段监测森林火灾，并提出了以MODIS 7波段为主的高温火点直接判别法和非高温火点综合阈值判别法。2006年重庆市森林火灾监测实践证明，该方法在城市森林火灾监测中是可用的。

| Abstract: | Forest fires have become a critical factor that affects the terrestrial ecosystems,and remote sensing is an important means for obtaining surface information.MODIS images have the merits of high spatial resolution and multispectra.A study of MODIS data can yield important data resources.The authors used near infrared,middle-far infrared,far infrared and thermal infrared MODIS bands to monitor the forest fires,mainly based on the MODIS 7 band and using Direct Criterion Method for high-temperature fires and Comprehensive Threshold Discrimination for non-high-temperature fires.It is proved that fire monitoring has very important significance for fire detection. |
