为探索低空交通与城市空间的协同发展路径，分析其对城市空间发展的潜在影响，进而制定前瞻性的应对策略，融合城乡规划与交通运输工程等多学科视角，综合运用文献分析法、对比分析法、归纳演绎法，梳理总结了过往城市交通方式变革如何影响城市空间发展，并结合低空交通的特性以及关于低空交通影响城市的既有研究，提出了低空交通在城市空间中的发展方案假设。通过研究得出低空交通对城市空间造成以下4个方面的影响：低空交通设施成为新的城市空间主体，城市空间用途边界复合化，城市空间冲突向三维延伸，以及城市空间蔓延发展趋势加强。在此基础上，提出国土空间规划的应对策略，包括：完善国土空间规划体系，前瞻性布局低空交通设施，融合传统交通发展，以及采用“空轨复合”空间开发模式。

To explore the pathways for the coordinated development of low-altitude transportation and urban space, analyze its potential impact on urban space development, and then formulate forward-looking response strategies, this paper integrates multidisciplinary perspectives from urban and rural planning, traffic and transportation engineering, etc. and comprehensively applies the methods of literature analysis, comparative analysis, and induction-deduction to review how the past transformation mode reform affected the development of urban space. Combined with the inherent characteristics of low-altitude transportation and existing research on its impact on cities, the paper proposes the development scenarios assumption of low-altitude transportation in urban space. Through the research, it is found that the low-altitude transportation has the following impacts on urban space: low-altitude transportation facilities are becoming the new dominant entities in urban space, the functional boundaries of urban space are becoming more integrated, urban space conflict is extending to three dimensions, and the urban space sprawl is intensifying. Based on these findings, the paper summarizes four response strategies of the territory spatial planning system: improving the territory spatial planning system, proactively planning low-altitude transportation facilities, integrating traditional transportation development, and adopting a "air-rail composite" spatial development mode.
