| 双碳政策目标背景下,轨交枢纽作为重要的城市基础设施在节碳减碳层面扮演着重要的角色。文章针对轨交枢纽建筑空间体量巨大,能耗影响因子复杂等特点,以及我国轨交枢纽绿色低碳评价体系规范、标准还不完善的现状,展开对轨交枢纽在前期建设阶段的绿色低碳评价的研究。通过采集经典轨交枢纽案例样本的绿色低碳数据进行分析和归纳,构建以自然环境因子、人文环境因子、科技创新因子三个维度,涵括6项一级指标和17项二级指标的评价框架体系,采用熵值法对评价指标进行权重计算,继而利用物元可拓理论构建较为完整的轨交枢纽绿色低碳评价模型,最后将评价模型应用在北京城市副中心枢纽项目中,根据评价结果对该项目相应的设计场景提出切实可行的提升建议。论文成果以期为相关研究和工程实践提供参考依据。 |

| Abstract: |
| In the context of China's dual-carbon policy objectives, rail hubs, as critical components of urban infrastructure, play a significant role in promoting energy conservation and reducing carbon emissions. As China's transportation sector continues to experience steady growth in passenger traffic, the associated energy consumption has reached unprecedented levels, especially with the rapid expansion of new railway lines. This has exacerbated the challenges of increasing urban energy demand and resource consumption. The large spatial scale of rail hubs, coupled with the complexity of energy consumption influencing factors, further underscores the urgency of addressing these issues. However, China's current standards and regulations for evaluating the green and low-carbon performance of rail hubs remain incomplete and underdeveloped, making it difficult to systematically assess and promote sustainable practices.This paper aims to address this gap by focusing on the green and low-carbon evaluation of rail transportation hubs during the pre-construction phase. We begin by identifying and analyzing the key issues hindering green development in China's rail hubs, examining them across three main dimensions: the natural environment, human factors, and technological innovation. These dimensions encapsulate the major challenges related to energy efficiency, resource management, and sustainability that need to be addressed for a more environmentally friendly rail hub infrastructure.To develop a more robust and comprehensive evaluation system, we collect and analyze data from case studies of existing rail hubs, focusing on their green and low-carbon performance. Based on these findings, we propose an evaluation index system that includes three core dimensions: natural environmental factors, humanistic environmental factors, and scientific and technological innovation factors. This system comprises six first-level indexes and seventeen second-level indexes, allowing for a detailed and nuanced assessment of a rail hubs sustainability performance.To further refine this evaluation system, we apply the entropy value method to calculate the weight of each evaluation index, ensuring an objective and data-driven approach to the assessment. In addition, we incorporate the theory of material elemental topology to build a more complete and integrated green and low-carbon evaluation model for rail hubs. This model offers a systematic framework for evaluating the sustainability of rail transportation infrastructure and can be adapted to various project scales and contexts.The proposed evaluation model is applied to a real-world case study of the Beijing Urban Sub-city Development Area, specifically the Beijing Urban Vice Center Hub project. By utilizing the evaluation results, we provide practical and feasible recommendations for improving the design scenarios of this major infrastructure project. These suggestions are grounded in both theoretical research and empirical analysis, offering actionable insights that can be implemented to enhance the project's environmental sustainability.In conclusion, the research presented in this paper aims to contribute to the development of more effective and comprehensive standards for evaluating the green and low-carbon performance of rail hubs in China. The findings are intended to serve as a reference for future research and engineering practice, promoting more sustainable and energy-efficient transportation infrastructure in alignment with national carbon reduction goals. |
