近20年来民航联合基金项目演进特征及未来展望
Research Hotspots and Prospects of NSFC-Civil Aviation Joint Research Fund in Recent 20 Years
摘要
Abstract
The NSFC-Civil Aviation Joint Research Fund serves national strategic needs,focuses on fundamental re-search for civil aviation applications,promotes scientific and technological innovation,and supports industry devel-opment through its research outcomes.To systematically understand the topic evolution of the NSFC-Civil Aviation Joint Research Fund projects,a text mining method combining word frequency analysis and latent Dirichlet alloca-tion(LDA)topic modeling is applied to analyze the topic selection guidelines and project approvals from 2004 to 2023.The study reveals the keyword characteristics of the guidelines,analyzes research hotspots and their evolution-ary trends,and provides the research prospects of civil aviation.The results indicate that:①The NSFC-Civil Avia-tion Joint Research Fund exhibits distinct phases and attracts diversified research forces.②The guidelines are high-ly consistent with national policies and strategic development directions.Keywords such as civil aviation,airport,aircraft,safety,emergencies,and NextGen have frequently appeared in the guidelines over the past 20 years,while low-altitude operation may emerge as a new hotspot in future.③The fund mainly focuses on 11 research topics,in-cluding aircraft airworthiness,airport construction and operation,air traffic management and optimization,aviation safety and risk management,emergencies and emergency management,green aviation,and so on.④Four topics in-cluding aircraft airworthiness,airport construction and operation,air traffic management and optimization,and avia-tion safety and risk management have remained hot in the past 20 years.The research hotspots in civil aviation are shifting from traditional infrastructure construction and safety technology fields to emerging fields such as informati-zation,intelligence,and green development.The trend is also moving from single-discipline dominance to multidis-ciplinary integration.Looking ahead,the future NSFC-Civil Aviation Joint Research Fund is expected to focus on constructing a digital intelligence ecology,enhancing system-wide safety,and promoting green development.By fos-tering multifaceted synergistic cross-fertilization and developimg an autonomous knowledge system,it aims to drive the high-quality development of civil aviation.关键词
