摘要
快速、准确的进行林火火源监测及定位可以有效缩短扑救时间,降低林业资源损失和自然环境污染.为了解决这一问题,采用地理信息系统(geographic information system,GIS)和遥感(remote sensing,RS)作为研究手段、运用实例研究的方法,以MapGIS开发平台为基础,设计并开发"森林防火监测预警系统"."遥感影像定位"和"视频图像定位"作为两种常用的监测定位手段,可以从宏观和微观的不同角度互补;火险等级预报为监测重点提供参考依据;火势推演分析紧密结合气象信息和植被信息模拟火场扩散情况.结果表明,GIS在森林防火监测定位方面不仅有着良好的可视性,其强大的空间分析特性尤为突出,对促进森林防火管理的信息化、科学化起到十分重要的作用.
Quick and accurate monitoring and positioning forest fire can help save precious time in fire fighting,reduce loss of forest resources and decrease environmental pollution.In order to achieve the goal,geographic information system（GIS） and remote sensing（RS） were used,and giver a real exploring example about using MapGIS as an explored platform,designing and realizing ＂forest fire fighting monitoring and warning system＂.As two popular monitoring and positioning technologies,remote sensing image positioning and video image positioning take advantage of each other in both macro and micro perspectives.Fire rating prediction provides a reference for monitoring the focus,and fire inference analysis of the close combination of meteorological information and vegetation information simulates the spread of fire.The exploring example proves that GIS has advantage of visibility in forest fire fighting monitoring,especially,its strong functions about spatial analysis promotes informational and scientific forest fire management.
