Abstract


Railway sustainable development of the implementation of the strategy and the railway green line selection request railway construction projects to determine the basic direction from the line, the line scheme comparison in line spatial location determine the layout of the building to the line must Considering the natural conditions and ecological environment, as small as possible damage to the quality of the environment along the railway construction project. The environment has a profound reasons of economics, it is very necessary to use of economic instruments to solve environmental problems. In this paper, on the railway the green line selection environment impact assessment of economic losses, environmental information into clear economic information. And the results of the assessment included in the cost - benefit analysis and line programs than the ideas and methods in the selection process, which the railway green line selection has a positive role in promoting and practical value. The thesis done the following work: First, China's railway construction project environmental impact of economic evaluation of the status quo, characteristics and main problems of the content and methods of the the green railway line selection evaluation study of the environmental impact of economic losses. Second, by analyzing the background, connotation, characteristics and technical development of the railway green line selection, basic theories and methods of the rail green line selection; assessment factor identification and screening, quantification and monetization of environmental damage model, consider the environmental costs of the generalized cost - benefit analysis of three environmental impact assessment theories and methods of economic loss system. Third, by identifying and screening green railway line selection environmental impact economic damage assessment factor, built evaluation index system and evaluation procedures; reasonable environmental valuation methods, soil and water resources, vegetation resources, biodiversity, natural landscape resources noise pollution, atmospheric pollution, six aspects monetization Measurement Research; environmental impact of the economic loss of value into the cost - benefit analysis, consider the environment affect the value of economic losses to the environment, including the cost - benefit analysis mode and rail green Line Selection comparison model for the railway the green line selection is preferably provided a basis for decision making. Fourth, the use of the VB2005 program design, rail Green Line Selection environmental impact of Economic Loss Alternatives of visual system function modules. Finally, to Wuhan New Area, special railway lines, for example, the environmental impact assessment process and methods of economic losses were instances of authentication.
