摘要

[Objective]The study aimed to discuss the effects of the adjustment of energy structure on daily average concentration of NO2 in different regions of Urumqi city in winter. [Method]The changes of daily average concentration of NO2 in different areas of Urumqi City from January to February (NO2 pollution was most serious) before and after the implementation of the project ' changing coal to gas' were analyzed. [Result]After the implementation of the project,daily average concentration of NO2 in different areas of Urumqi City was increased due to the rapid increase of vehicle quantity,but there were certain differences in the increase among various regions. From south to north,daily average concentration of NO2 in winter was decreased gradually,that is,daily average concentration of NO2 was the highest in the south area,while in the north area,it didn’t change significantly before and after the implementation of the project,but it was still high. Therefore,the local government should pay more attention to pollution NO2 during environmental management process. [Conclusion]The research could provide scientific references for the control of atmospheric pollution in future.
