【摘要】 作为低空经济核心载体，低空飞行器面临暴雨、雷电等灾害天气引发的安全风险。通过VOSviewer软件的文献计量分析揭示低空飞行器的研究热点，系统探讨灾害天气对低空飞行器运行安全的影响；针对无人机风险评估问题，探讨各风险评估方法在灾害天气下的评估有效性及优缺点。特别强调风险场模型在低空空域的应用，尤其对比飞行风险场和道路风险场的各个维度特征，以期为研究人员制定灾害天气下低空飞行器安全飞行方案提供参考。更多还原

【Abstract】 As the core infrastructure of the low-altitude economy,low-altitude aircraft face significant safety risks induced by disaster weather events such as torrential rain and lightning.Bibliometric analysis and VOSviewer software are employed to identify research hotspots in the field of low-altitude aircraft.Disaster weather types are systematically classified,and their impact mechanisms on operational safety are investigated.The effectiveness of risk assessment methods for unmanned aerial vehicles (UAVs) under disaster weather conditions is analyzed,with comparative advantages of different approaches being evaluated.Emphasis is placed on the application of risk field models in low-altitude airspace,and a dimensional comparison between flight risk fields and road risk fields is conducted to support the development of safe flight strategies in extreme weather.更多还原
