摘　　要：介绍了EOS/MODIS资料在西藏森林火灾监测中的应用,并用多年的历史资料来验证,说明该方法在该区森林火灾监测中是可行的。同时为实现对非林火的排除并提供着火点树种信息,利用ENVI、R2V、ARCGIS等软件对西藏地区森林资源分布图进行了数字化录入,以ArcView为平台,对西藏地区遥感影像与地面森林分布信息图像进行了复合。研究表明,运用该方法排除非林火,效果较好。The application of EOS/MODIS data in the monitoring of forest fire in Tibet was introduced.And the multi-year historical data were used to validate it.The results indicated that this method was feasible in the monitoring of forest fire in this region.In order to realize the elim-ination of non-forest fire and provide the tree species information of burning point,the digital input of the distribution map of forest resources in Tibet was conducted by using ENVI,R2V,ARCGIS software.Taking Arcview as the platform,the remote sensing image and surface distribution map of forest were overlaid.The results showed that the elimination effect of non-forest fire by using this method was better.
