摘　　要：概述了利用NOAA-AVHRR数据进行林火监测的原理和4种方法。针对吉林省东部的森林火灾,运用4种方法进行了火点信息提取与分析,最后对阈值法进行了改进,提取精度达到了89.2%。分析了NOAA-AVHRR应用于林火遥感监测的可行性和不足。This paper describes the principle of fire detection by using NOAA -AVHRR data, and-gives a brief summary of four fire detection methods. Four fire detection algorithms were utilized to detect and analyze several forest fire spots that occurred in eastern Jilin Province. This paper discusses the fixed threshold method and makes some improvement. Compared with the results of fire detection by other methods, the accuracy of the improved method is obviously＇higher and can reach 89.2%. The capability of the improved method for fire detection and its shortcomings are also discussed.
