基于SEM-FCE的站城融合立体网络空间运行性态环境影响机理研究
Mechanism of Environmental Impact on Operational Performance of Station-City Integrated Three-Dimensional Network Based on SEM-FCE
站城融合已成为城市发展与交通建设的核心战略之一。为推动站城融合深入发展并提升运行性态,研究聚焦于站城融合背景下综合交通枢纽站域空间,以环境影响机理为切入点,采用结构方程模型与模糊综合评价法,从环境安全性、舒适性、便捷性和可持续性4个维度综合构建站城融合立体网络空间运行性态环境评价体系,量化分析各环境指标与运行性态的关系。研究结果显示,各环境维度对运行性态的影响存在差异,重要性排序依次为:环境便捷性、舒适性、可持续性和安全性。模糊综合评价表明,研究区域环境机理对运行性态的综合影响得分为61.876,处于“好”等级,但环境安全性和可持续性仍有提升空间。本研究明确了环境机理的影响路径与权重,为站城融合立体网络空间的规划设计、功能优化及高效运营提供了量化依据,对提升城市交通效能与空间价值具有实践指导意义。
Station-city integration has become one of the core strategies in national urban development and transportation construction. To promote its in-depth development and enhance its operational performance, this study focused on the spatial areas of integrated transportation hubs under the background of station-city integration. Taking the mechanism of environmental impact as the entry point, it adopted the structural equation modeling (SEM) and fuzzy comprehensive evaluation (FCE) methods. A comprehensive evaluation system for the operational performance environment of the station-city integrated three-dimensional (3D) network was constructed from four dimensions: environmental safety, comfort, convenience, and sustainability, so as to quantitatively analyze the relationships between various environmental indices and operational performance. The research results show that there are differences in the impacts of various environmental dimensions on operational performance, with the order of importance being: environmental convenience, comfort, sustainability, and safety. The FCE indicates that the comprehensive impact score of the environmental mechanism on operational performance in the study area is 61.876, which is a "good" grade. However, there is still room for improvement in environmental safety and sustainability. This study clarifies the influence paths and weights of the environmental mechanism, providing a quantitative basis for the planning and design, functional optimization, and efficient operation of the station-city integrated 3D network. It also has practical guiding significance for improving urban transportation efficiency and spatial value
