摘要
森林火隆对江西森林危害极大。根据江西省气候情况及森林分布状况，每年１０月至次年４月是江西省林火高发期。利用ＮＯＡＡ极轨卫星ＡＶＨＲＲ第三通道资料，结合地面森林分布状况及当时天气条件能有效地监测森林火灾，并通过ＡＶＨＲＲ３，４通道辐射温度的差异计算森林火灾面积。
Forest fires endanger forests seriously in Jiangxi Province, According to the climatic infor-ma tion and forest distribution condition of Jiangxi Province,The major period during whichforest fires take place mostly is that from October to April of the following year. Making use ofNOAA/AVHRR data of channel three and weather condition at the same time,We can effec-tively monitor forest fires and calculate the fired forest areas by temperature differences of radi-ationbetween AVHRR data of Channel 3 and those ofchannel 4.
