摘　　要：在地理模拟系统理论基础之上,结合动态数据驱动应用系统技术范式,提出了林火模拟全新的技术框架和结构体系。探索林火模拟系统建设过程中的模型库建设与管理、模型适宜性选择、模型自适应修正、模拟过程实时验证和林火空间扩散模拟等关键技术。研究结果表明,林火模型的自动化和智能化选择精度可达到75%,模型模拟误差修正也达到了较为理想的效果。随着系统建设的进一步完善,本系统将与北京市林火管理业务化运行系统集成,这将进一步提高林火扑救的指挥决策能力。Based on geographical simulation system theory and taking dynamic data driven application systems as technological paradigm,this paper brought forward a new fire simulation technology framework and network system,solved the key technology in the simulation system building process such as model base construction and management,model suitability selection,model adaptive correction,real-time simulation validation,forest fire space spreading simulation,and so on.Automation and intelligent selecting precision of the forest fire model reached more than 75%.Model error correction simulation reached a more satisfactory result.With the further improvement of system construction,the system will integrate with the operational system,and improve the forest fire fighting decision-making.
