HE Ji-cheng(Division of Environment and Resources Research,Transport Planning and Research Institute,Ministry of Transport,Beijing 100028,China)  
Although aircrafts are of great importance in transportation in China,there has been rare study on air pollutant emissions of aircrafts until now.Based on the annually statistical data collected by the Statistic Center of Civil Aviation of China,using the emission factor method derived from fuel consumption,the air pollutant emissions of aircrafts during 1980-2009 were calculated,and their emission intensities and dynamic characteristics were analyzed.The results show that the emissions of SO2,CO,NOx and HC from aircrafts of China Civil Aviation increased from 0.31 thousand,1.89 thousand,2.25 thousand and 3.14 thousand tons in 1980 to 11.83 thousand,72.98 thousand,87.05 thousand and 121.59 thousand tons in 2009,indicating a increase of 0.397 thousand,2.45 thousand,2.92 thousand and 4.08 thousand tons per year,respectively.The emission intensities of SO2,CO,NOx and HC decreased significantly from 0.624,3.806,4.53 and 6.322 g·(t·km)-1 in 1980 to 0.275,1.697,2.025 and 2.828 g·(t·km)-1 in 2009,respectively.SO2,CO,NOx emissions of aircrafts of China Civil Aviation accounted very little of each total emissions in China,and the air pollutant emissions from aircrafts of China Civil Aviation was less than those from other industries in China.
