Environmental Pollution Evaluation of Urban Rail Transit Construction Based on Entropy Weight Method

With the development of cities, urban rail transit has entered into a stage of rapid construction and development, but the environmental pollution caused by rail transit construction cannot be ignored. To evaluate the environmental pollution of urban rail transit construction, an evaluation system for the environmental pollution induced by urban rail transit construction was established by using the literature survey method and the entropy weight method. The evaluation index system involved three first-level indicators of the physical environment, natural environment and social environment, and 11 second-level indicators. The impact of XA-XDM project construction on urban environmental pollution in Wuhan, China was evaluated by using the evaluation system. Results show that the evaluation score of XA-XDM project is 76.5, which means that the XA-XDM project construction has a strong impact on environmental pollution. It should be paid to the prevention, control and monitoring of various pollution indicators, reducing environmental pollution, and realizing green construction.
