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 the theory of geo-simulation system and combining with the dynamic data-driven application system technology paradigm, a new technical framework and structure system of forest fire simulation is proposed. This paper explores key technologies such as construction and management of model library, selection of model suitability, adaptive modification of model, real-time verification of simulation process and simulation of forest fire diffusion in the process of building forest fire simulation system. The results show that the accuracy of automatic and intelligent selection of forest fire model can reach 75%, and the simulation error correction of model reaches the ideal effect. With the further improvement of the system construction, the system will be integrated with the operational management system of Beijing Forest Fire Management, which will further improve the command and decision ability of forest fire suppression.
