摘要
基于中国铁路部门逐年统计数据,计算了1975—2007年中国电气化铁路带来的逐年节能量和CO2、烟尘、SO2、CO、NOX与CnHm的直接减排量,并分析了其变化特点。结果表明,33年来电气化铁路使得中国铁路运输行业年均节省123.0万t标准煤的能源消耗,节能量年均增长13.9万t标准煤;CO2、烟尘、SO2、CO、NOX和CnHm年均直接减排量分别为426.7万t、2.05万t、0.30万t、0.96万t、6.79万t和0.69万t,直接减排量年均分别增长48.3万t、0.23万t、0.034万t、0.11万t、0.77万t和0.078万t。电气化铁路为减少中国铁路行业的能源消耗、温室气体和大气污染物的直接排放发挥了重要作用。
Based on the annual production data collected by Statistic Center of Chinese Railway Ministry,we calculated the energy saving,and the direct emission reductions of CO2,soot,SO2,CO,NOX and CnHm of electrified railways,and analyzed their dynamic characteristics during 1975-2007.The results show that during the past 33 years,the annual mean values of energy saving and the direct reductions of CO2,soot,SO2,CO,NOX and CnHm emissions were 1.230 Mt ce （coal equivalent）,4.267 Mt,20.5 kt,3.0 kt,9.6 kt,67.9 kt and 6.9 kt,respectively.The average growth rates of energy saving and direct reductions of CO2,soot,SO2,CO,NOX and CnHm emissions were 139 kt ce,483 kt,2.3 kt,0.34 kt,1.1 kt,7.7 kt and 0.78 kt per year,respectively.The electrified railways played an important role in decreasing the energy consumption and air pollutants emissions of Chinese railway system in the past 33 years.The study results could provide some reference knowledge for future reduction of energy consumption and waste gases emission in Chinese railway transportation.
