基于森林火险指数的森林火险实时预警系统

Real-Time Forest Fire Warning System Based on the Forest Fire Danger Index

利用森林火险指数仪进行森林火险实时监测,以ArcGIS Engine10作为开发平台、以SQL server 2005作为数据库设计开发了森林火险实时预警系统。系统构建包括森林火险指数仪的选址、火险指数和火险等级计算及专题图制作、信息发布。系统能以简明的电子地图和二维表,直观显示火险指数、火险等级的监测结果及其空间分布特征。以四川仁寿为例,展示了森林火险预警功能的实现过程和效果。结果表明,预警系统能够对森林火险进行实时监测与及时预警,有利于对森林火灾进行合理预防。

Considering the Renshou region in the Sichuan province as an example,authors showed the process and effect of the operation of such a system.Using forest fire danger index instruments to monitor forest fire risk grades in real time,a real-time forest fire warning system was designed using ArcGIS Enginel0 as the platform and using SQL Server 2005 as the database.The proposed system consists of three processes：selecting the appropriate locations to install the forest fire danger index instruments,calculating the fire danger index and fire risk grade,and plotting thematic maps and information issues.Owing to such a system,fire risk grades and their spatial distribution can be displayed on electronic maps and datasheets.The proposed system was tested in Renshou region in the Sichuan province,and the results showed that the forest fire warning system can predict forest fire risks rapidly and in real time; thus allowing us to adopt preventative or protective measures against potential fires.
