摘要:根据对近年来多次特大森林火灾和相应的气象卫星资料的分析,提出利用NOAA/AVHRR数据测算森林大火的过火面积的四种方法,即灰度修正像元法、植被修正像元法、坐标法和蔓延法。在GIS地面信息数据库支持下,利用这4种方法能准确、快速地计算出过火面积。经今春应急评估试运行验证,森林大火过火面积测算精度达90%。
お? Four methods of evaluating burned area of big forest fire,counting pixels corrected by pixelvalue,counting pixels corrected by NDVI,calculating coordinators of boundary pixels and spreadingmethod,are presented through analyzing the material about vast area of forest fire in resent years and relative NOAA/AVHRR data.The above methods,based on GIS database,to evaluate the burned area of forest fire are accurate and fast.In this spring,there was a forest fire in the Inner Mongolia,the accuracy of evaluating burned area by using these methods is 90 percent.
