Abstract: Air pollution of Urumqi is very serious in winter. In past decades, the concentration of NO2 increased rapidly, which has become an environmental problem that can not be ignored. In order to improve the serious air pollution in winter, the local government has implemented the "Coal to Gas" project. Whether the project played a decisive role in controlling concentration of NO2? This paper chooses the most serious pollution period of winter (1~2 months), and analyzes the change of daily average concentration of NO2 before and after "Coal to Gas" in different areas of the city. The results show that after the project, instead of decreasing, the concentration of NO2 was increasing due to the Motor Vehicle increased rapidly. From South to North, the average concentration of NO2 decreased gradually in winter. In South area, the daily average concentration of NO2 was very high, while in North area, it didn’t make much change, which worth paying attention to the environmental management process by the local government.
