目的 深入调查全龄层次的人群对智慧城市公共空间的态度，为未来城市规划和设计提供实际可行的建议，推动城市发展朝着更为包容、互动和可持续的方向迈进。方法 首先，通过实地调查收集的数据，分析不同年龄段人群的需求和行为特点，提出相应的设计策略;其次，运用地理信息系统(GIS)技术、建筑信息模型(BIM)软件、虚拟现实(VR)呈现技术等，以实现空间的可视化、模拟和交互;最后，通过这些技术的应用，实现对城市公共空间的实时监测、数据分析和智能管理，提供更加便捷、安全和舒适的环境。结果 智慧城市公共空间设计充分考虑不同年龄段人群的需求和能力，创造出适应全龄段的、安全、舒适、便捷、有趣且具有社交互动性的公共空间。结论 全龄友好视角下的智慧城市公共空间设计需要综合运用多种技术和软件，以实现空间的智能化和人性化。通过深入解析相关技术，可以为城市规划和设计提供科学依据，创造更加宜居、宜业、宜游的城市环境。

The work aims to deeply investigate the attitudes of people of all ages towards the public space of smart cities, to provide practical suggestions for future urban planning and design, and promote urban development towards a more inclusive, interactive and sustainable direction. Firstly, through the data collected by field investigation, needs and behavior characteristics of different age groups were analyzed, and corresponding design strategies were put forward. Secondly, geographic information system (GIS) technology, building information model (BIM) software, virtual reality (VR) rendering technology, etc. were applied to achieve spatial visualization, simulation and interaction. Finally, through the application of these technologies, real-time monitoring, data analysis and intelligent management of urban public space were realized to provide a more convenient, safer, and more comfortable environment. The design of smart city public space fully considers the needs and abilities of people of different ages, and creates a public space that is safe, comfortable, convenient, interesting and socially interactive. The design of smart city public space from the perspective of all-age friendliness requires the comprehensive use of various technologies and software to realize the intellectualization and humanization of space. Through in-depth analysis of related technologies, it can provide a scientific basis for urban planning and design, and create a more livable, industry-friendly and tourism-friendly urban environment.
