秦岭多源卫星森林火情监测预警系统设计及应用

Design and Application of Qinling Multi-Source Satellite Forest Fire Monitoring and Early Warning System

利用多源卫星数据,基于多光谱遥感、AI识别、深度学习等技术,研究本地化动态火点识别阈值调整技术、火险因子评估模型、气象火险指数、过火区判识等方法,构建基于多源卫星影像的智能火点识别算法,开展秦岭火情网格化、全天时、全覆盖的精细化监测、预警、预报,研发秦岭多源卫星森林火情监测预警系统,实现火点监测、预警及评估等功能。系统智能化程度高,业务操作简捷,多角色用户,安全性较高。在西安市、秦岭西安段、秦岭区域的森林防火工作中业务化应用,实现了对疑似火点的快速定位、连续监测,与相关部门建立及时反馈机制,确认火点真实性,为制定合理林火扑救方案,提供了更加准确的信息支撑;基于高分卫星的灾后评估为开展灾后修复提供了有效的卫星监测依据;本地化的森林火险气象等级预报,守好气象防灾减灾第一道防线。系统为实现“打早、打小、打了”提供技术支持,为提高秦岭防火能力发挥积极作用。

Using multi-source satellite data, based on multi-spectral remote sensing, AI recognition, indepth learning and other technologies, research the dynamic fire point recognition threshold adjustment technology, fire risk factor evaluation model, meteorological fire risk index, fire zone identification on localized, build an intelligent fire point recognition algorithm based on multi-source satellite images, carry out fine-grained monitoring, early warning, and prediction of Qinling fire situation in a grid, all day and all coverage manner, researched and developed the Qinling multi-source satellite forest fire monitoring and early warning system, implement functions such as fire point monitoring, early warning, and valuation. The system has a high degree of intelligence, simple business operations, multiple role users, and high security. The business application in forest fire prevention work in Xi’an City, the Xi’an section of the Qinling Mountains, and the Qinling region has achieved rapid positioning and continuous monitoring of suspected fire points, established a timely feedback mechanism with relevant departments, confirmed the authenticity of fire points, and provided more accurate information support for formulating reasonable forest fire extinguishing plans;the post disaster assessment based on high-resolution satellites provides an effective satellite monitoring basis for carrying out post disaster restoration;localized forest fire risk meteorological level forecasting, and maintaining the first line of defense for meteorological disaster prevention and reduction. The system provides technical support for achieving “early strike, small strike, and late strike”, and plays a positive role in improving the fire prevention capacity of Qinling Mountains.
