摘要: 对1998年旺季(4月~10月)的中国上空民航飞机的NOx排放量及其分布进行了评估,并结合国内外有关数据进行了分析和比较.结果表明,目前中国的商业飞行所造成的NOx排放主要集中在(大)城市上空,各城市上空的大气污染程度有很大的不同,且这些城市上空的NOx含量沿高度方向由地面向高空递减;就自身发展来看,目前的高空飞机NOx排放量已比6年前增加1倍多;从横向比较来看,目前中国几个大城市上空飞机的NOx排放量已达到并超过6年前全球空运发达地区的排放量,应引起有关部门的高度注意.

Abstract: On the basis of CAAC timetable and route setting, and according to individual aeroplanes and aeroengines, the present paper simplified and modeled the operation of each flight. Moreover, using the popular fuel flow method and by means of the emission databanks published by ICAO and NASA,the inventory of NOx emitted from CAAC flights in April to October of 1998 was assessed. The results show that NOx emissions from current commercial airplanes over China are concentrated on some big cities. The concentrations of NOx over different cities have great differences. The NOx emissions over China have doubled comparing with 6 years ago. And the NOx emission level over several Chinese big cities is about the same as that of some big cities in developed countries at 6 years ago.
