摘　　要：空气中的氮氧化物(NOX)是发达国家和我国大中城市的主要污染物之一,对人体健康和生态环境造成严重危害,NOX已列入空气质量预报项目。本研究以南昌市为对象,针对NOX的污染特点,按点源、面源和线源采用综合模式建立了南昌市NOX污染预报模型,开发了预报系统软件,模拟精度和预报精度分别达到了51%和60%以上,符合预报要求,为南昌市NOX预报提供了科学的方法和手段,对我国其它大中城市开展NOX预报具有参考价值。In developed countries and some big cities in China NO_X is one of the most primary air pollutants,which is harmful to people and environment,and is also one of the items of air quality forecasting.Based on factual status of Nanchang City,NO_X pollution forecasting models are established in this research for differnt NO_X pollution sources(point source pollutions,non-point source pollutions,line source pollutions),which adopt integrated models,and a forecasting software has been also designed,whose simulating precisions and forecasting precisions exceed 51% and 60% respectively.It accords to the require of forecasting,which provides the scientific ways for NO_X pollution forecasting in Nanchang City and other big cities in China.
