基于低碳物流的煤炭运输灰色关联分析

Low-Carbon Considered Coal Transportation Gray Relations Analysis

为对煤炭运输过程中碳排放进行评估,引入"电煤运输环节碳排放系数",应用不同时期火力发电的数量,测算出我国2003-2007年的电煤运输环节总的碳排放量,并将该排放量与相应的煤炭运输方式进行了灰色关联分析。结果表明,煤炭公路运输与CO2排放的关联度较为显著,水路运输与铁路运输与CO2排放的关联度相差不大,因此我国煤炭运输应当大力发展铁路运输和铁-海联运,煤炭运输向低碳物流化转型。

To evaluate the carbon emissions of the coal transportation process, the paper introduces the concept of thermal coal transport carbon emissions coefficient and, in light of the different scales of thermal power generation at different periods, estimates the total volume of carbon emissions for this process during 2003 and 2007. Then it covrelates the volume with corresponding transport means using gray relations analysis and finds that CO2 emissions are highly correlated with highway transportation and least so with waterway transport.
