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, the study collects and
analyzes data from case studies of existing rail hubs, focusing on their green and low-carbon
performance. Based on these findings, it proposes 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 secondlevel
indexes, allowing for a detailed and nuanced assessment of a rail hubs sustainability
performance. To further refine this evaluation system, it applies the entropy value method to calculate
the weight of each evaluation index, ensuring an objective and data-driven approach to the
assessment. In addition, it incorporates 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 realworld
case study of the Beijing Urban Sub-city Development Area, specifically the Beijing Urban
Vice Center Hub project. By utilizing the evaluation results, it provides 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. |
