摘要
运用经过数字图像处理的TM图像,进行森林火险因子空间数据采集,在综合分析评价的基础上编制了可燃物类型分级表和森林火险等级分析表.并运用GIS空间数据库管理中的图像叠加、自然属性库进行分类,以及选用合适的火险等级模型,做出森林火险区划,为广州市森林防火工作提供了科学依据.
In this study, two maps are complied by using TM image through digital image processing and spacedata of forest fire danger collecting. They are the table of Classification of Forest Fuel Types and the table of Classification of Forest Fire. By employing the image superposition in management of GIS spacedata bank and natural attribute bank, and selecting a suitable forest danger model, the distribution table of forest fire hazards for Guangzhou City has been drawn out, thus offering some scientific evidence for its forest fire prevention.
