Abstract

Research purposes: With the continuous improvement and rapid construction of China's railway network, the impact of railway engineering on the ecological environment along the routes has become increasingly evident. Particularly in ecologically fragile desert regions, the issue of environmental pollution during railway construction is more pronounced. Although green construction practices have been widely adopted in railway development, there is still a lack of systematic environmental impact assessment frameworks and methodologies, making it difficult to accurately evaluate the actual environmental impact of construction activities and to provide a scientific basis for environmental management decisions. In light of this, this paper aims to establish a scientifically sound environmental pollution evaluation index system for green railway construction in desert areas, comprehensively reflecting the impact of construction activities on water environment, atmospheric environment, acoustic environment, solid waste disposal, and ecosystems. Furthermore, it seeks to develop a quantitative environmental impact assessment model to achieve an objective evaluation of the environmental impact of green railway construction. Lastly, through empirical research, the paper intends to validate the effectiveness of the evaluation system, providing theoretical support and practical guidance for formulating targeted environmental protection measures.
Research conclusions: (1) This paper constructs an environmental pollution evaluation index system for desert railway green construction, comprising 5 first-level indicators and 16 second-level indicators. It innovatively combines the entropy weight method with the fuzzy comprehensive evaluation method to establish a quantitative environmental impact assessment model. Using this model, the paper evaluates the environmental pollution impact of green construction on a section of the Golmud-Korla Railway. The environmental pollution evaluation grade for this section is "weak", indicating a relatively minor environmental impact. (2) Ecological disruption is the primary factor causing environmental pollution in railway green construction, and protective measures should be implemented during construction to effectively control it. (3) This evaluation index system can provide a direction for further improvement in the prevention and control of environmental pollution in railway green construction, offering reference value for optimizing construction measures and improving pollution management methods. It holds reference value for reducing environmental pollution and achieving high-quality green railway construction.
