摘要
研究目的:在揭示铁路节能与碳减排相关关系的基础上,通过建立碳排放计算模型,测算我国铁路运营近年来碳排放量的变化;通过确定铁路运营碳排放的影响因素及权重,建立低碳效应评价体系,为铁路节能减排提供评价工具。研究结论:(1)铁路运营中能耗量直接决定碳排放量,通过引入相关系数即可将能耗量转换成对应的碳排放量;(2)由于铁路运营中大量使用清洁能源电能,从严格的意义上看,电能本身并不直接产生碳排放,因此,铁路能耗又不完全等同于碳排放,需要在碳排放量计算时加以明确说明;(3)技术评价和管理评价构成评价体系的主要内容,通过层次分析法和专家打分法,可以确定各层次权重;(4)本文提出的碳排放量测算方法和低碳效应评价体系,可应用于铁路行业的碳排放统计、监测及评价等项工作。
Research purposes： This paper aims at estimating the change of carbon emission from railway operation in recent years through the establishment of carbon emission calculation model on the base of revealing the relationship between energy saving and carbon emission reduction in railway operation. And it also aims to establish the system of evaluation on low -carbon effect by determining the factors affecting railway carbon emissions and their weight in order to offer the evaluation tool to energy saving and emission reduction. Research conclusions： The analytic result shows that energy consumption directly determines the carbon emissions, therefore by introducing the correlation coefficient energy consumption can be converted into carbon emissions. Because a lot of clean energy is used in the railway operation, and in the strict sense, the power itself does not directly generate carbon emissions, the energy consumption of railway is not entirely equivalent to carbon emissions, that need to be clearly stated in the carbon emissions calculation. Technology assessment and management evaluation are the main factors of evaluation system, and by using the AHP and expert scoring method, the weights of all levels can be determined. The method to calculate the carbon emissions and the system of evaluation on low - carbon effect presented in this article can be applied in such fields including emissions statistics, monitoring and evaluation in the railway sector.
