【摘要】 低空经济正推动城市空间向三维立体拓展，低空空域已转变为亟需地面系统深度支撑的立体运行空间。本文以低空空域规划为核心，在梳理国内现状基础上，对比研究了美国先进空中交通（AAM）的战略逻辑、欧洲U-space的服务化治理及日本的低空应用场景化实验等政策及实践。基于国际经验，文章探讨了面向地—空协同规划响应的低空空域规划路径：建议在空间层面从空中航线转向地—空垂直协同、设施层面统筹能源—交通—信息多网体系、运行层面以数字化设计支撑差异化发展，并将社会许可纳入规划评估框架，旨在为我国相关低空空域规划治理提供参考。更多还原

【Abstract】 The low-altitude economy is driving the expansion of urban space into the third dimension, transforming low-altitude airspace into a volumetric operational space that necessitates deep support from ground-based systems. Focusing on low-altitude airspace planning and reviewing the current status in China, this paper conducts a comparative study of strategic logic of advanced air mobility(AAM) in the United States, the service-oriented governance of U-space in Europe, and the scenario-based experimentation in Japan. Drawing on these international experiences, the study explores planning response pathways oriented toward “ground-air integration”. It proposes transcending the limitations of isolated airspace designation by integrating “energy-transport-information” into volumetric operational units and incorporating the “social license” into the planning assessment framework. The findings aim to provide theoretical references and practical guidance for relevant planning endeavors.更多还原
