以铁路建设可行性研究阶段的线路方案比选为目标,对铁路建设环境影响展开了经济分析,运用环境经济学的有关理论方法,在综合比较的基础上,选定适合铁路建设特点的环境影响经济分析方法,并对其货币化表示方法进行归纳总结.在此基础上,分析了铁路在选线过程中对景观、噪声、生态这三方面造成的影响,采用了定性定量相结合的方法,用以评估线路方案环境影响造成的经济损失,便于决策者更直观地认识到各个线路方案在环境影响方面的差别,最后在宣杭线增建第二线工程中进行实例应用.
Taking the comparison and selection of railway schemes during the feasibility study phase of railway construction as an objective, this paper carries out an economic analysis on the environmental impact of railway construction and applies the relevant theoretical methods of environmental economics. On the basis of comprehensive comparison, the environmental impact of railway construction is selected Economic analysis, and summarizes its monetization methods.On this basis, it analyzes the impact of railways on landscape, noise and ecology in the process of route selection, and adopts the method of combining qualitative and quantitative analysis, Which is used to evaluate the economic loss caused by the environmental impact of the route plan and make it easier for policymakers to recognize the difference in environmental impact of each route plan. Finally, an example application is made in the second line project of the Xuanhang Line.
