| 摘 要： | 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CO2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CO2年排放量逐年降低,内燃机车的CO2年排放量逐年上升,铁路机车CO2总排放量由1975年的4223万t降至2005年的1640万t,CO2排放强度呈现明显的降低趋势,年均降低2.4g/换算吨公里。我国铁路机车的CO2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。

| Abstract: | Based on the annual production data collected by Chinese Railway Statistic Center, the CO2 emission of locomotives during 1975-2005 was calculated and the emission intensity and its dynamic characteristics were analyzed. The results show that the CO2 emission of steam locomotives decreased while that of diesel locomotives increased with time because more diesel locomotives and electric locomotives were continually put into service to replace steam locomotives. The total CO2 emission of locomotives in China's railway network decreased from 42.23 million t in 1975 to 16.40 million t in 2005. The emission intensity of CO2 from two kinds of locomotives decreased at an average rate of 2.4 g/(converted t·km) per year. The proportion of the CO2 emission of locomotives to the total emission in the sector of transportation, storage and post in China also persistently decreased from 1980 to 2005. |
