为评估在森林火灾救援中通航飞行任务调度方案的安全性，通过对各通用航空器的航迹冲突进行检测，提出通航救援任务调度方案安全性评价指标。通过空域栅格模型建模救援飞行环境，基于任务调度方案针对性能约束不同的航空器规划出各自救援飞行航迹并进行航迹冲突检测，从而对任务调度方案进行安全性评估。仿真结果表明：该方法相较于直接冲突判断算法时间效率提升了53.8%，相较于高效的时空同步航线冲突检测方法准确率提升了6.7%，可见该方法能够高效准确地对救援飞行中的航迹冲突进行预测并评估任务调度方案的安全性，为通航救援指挥调度工作提供有效的决策支持。

To evaluate the safety of navigation flight task scheduling schemes in forest fire rescue, safety evaluation indicators for navigation rescue task scheduling schemes were proposed by detecting the flight path conflicts of various general aircraft. Using an airspace grid model to model the rescue flight environment, and planning the rescue flight paths of aircraft with different performance constraints based on their respective task scheduling schemes, and conducting trajectory conflict detection to evaluate the safety of the task scheduling scheme. The simulation results show that this method has a 53.8% improvement in time efficiency compared to the direct conflict detection algorithm, and a 6.7% improvement in accuracy compared to the efficient spatiotemporal synchronous route conflict detection method. It can be seen that this method can efficiently and accurately predict track conflicts in rescue flights and evaluate the safety of task scheduling schemes, providing effective decision support for navigation rescue command and scheduling work.
