The energy consumptions of aircrafts during 1960 -2009 are calculated, and the energy consumption intensity and its dynamic characteristics are analyzed, based on annual statistical data collected by Chinese Civil Aviation Statistic Center. The results show that the energy consumption of aircrafts in China increases at a rate of 0.4024 Mt standard coal equivalent per year. The energy consumption intensity of aircrafts decreases from 1.42 kg standard coal equivalent (converted t km) -1 in 1960 to 0.46 kg standard coal equivalent (converted t km) -1 in 2009 at an average rate of 19.6 g standard coal equivalent (converted t km) -1 per year. The energy consumption of aircrafts exceed that of locomotives since 2002. The proportion of aircrafts energy consumption to that of vehicles in China is 4.4％. This study can provide some valuable data on the status quo of energy consumption of civil aviation of China. Furthermore, the estimation presented in this paper can also give some suggestions for making energy saving strategy in China civil aviation.%根据中国民航多年的统计数据,探讨了1960-2009年中国民航飞机的逐年能源消耗量,分析了中国民航飞机的能耗强度及其变化.结果表明,1960年至2009年,中国民航飞机年耗能总量呈上升趋势,年均能耗增长40.24万吨ce.其能耗强度呈降低态势,其值从1960年的1.42kg ce/换算吨公里降至2009年的0.46 kg ce/换算吨公里,年均降低19.6 g ce/换算吨公里.民航飞机2002年的耗能量已经超过铁路机车,与我国机动车耗能相比,民航飞机耗能量较少,仅占后者的4.4%.该研究对明确多年来中国民航运输行业飞机能耗状况及其年际变化具有一定的意义,可为中国民航运输行业制定节能对策提供依据.
