基于我国铁路部门逐年统计数据,计算了1975-2005年我国铁路机车的CO2排放量,分析了我国铁路机车CO_2排放强度及其变化特点.结果表明,由于蒸汽机车不断被内燃机车和电力机车所取代,我国蒸汽机车CO_2年排放量逐年降低,内燃机车的CO_2年排放量逐年上升,铁路机车CO_2总排放量由1975年的4223万t降至2005年的1640万t,CO_2排放强度呈现明显的降低趋势,年均降低2.4 g/换算吨公里.我国铁路机车的CO_2排放量占整个交通运输仓储和邮政行业CO2排放量的比重也呈逐年降低趋势.
基于我國鐵路部門逐年統計數據,計算瞭1975-2005年我國鐵路機車的CO2排放量,分析瞭我國鐵路機車CO_2排放彊度及其變化特點.結果錶明,由于蒸汽機車不斷被內燃機車和電力機車所取代,我國蒸汽機車CO_2年排放量逐年降低,內燃機車的CO_2年排放量逐年上升,鐵路機車CO_2總排放量由1975年的4223萬t降至2005年的1640萬t,CO_2排放彊度呈現明顯的降低趨勢,年均降低2.4 g/換算噸公裏.我國鐵路機車的CO_2排放量佔整箇交通運輸倉儲和郵政行業CO2排放量的比重也呈逐年降低趨勢.

Based on the annual production data collected bv Chinese Railway Statistic Center,the CO_2 emission of locomotives during 1975-2005 was calculated and the emission intensity and its dynamic characteristics were analyzed.The results show that the CO_2 emission of steam locomotives decreased while that of diesellocomotives increased with time because more diesel locomotives and electric locomotives were continually put into service to replace steam locomotives.The total CO_2 emission of locomotives in China's railway network decreased form 42.23 million tin 1975 to 16.40 million tin 2005.The emission intensity of CO_2 from two kinds Of locomotives decreased emission in the sector of transportation,storage and post in China also persistently decreased from 1980 to 2005.
