摘要
通过对乌鲁木齐市2011—2013年采暖期SO2、NO2、PM10的年均浓度、月均浓度、日均浓度的变化比较,分析了乌鲁木齐市煤改气工程实施前后大气环境发生的变化趋势,论证了乌鲁木齐市煤改气工程对城市大气环境的改善作用,为该工程今后的推广与发展得到了可靠的实践依据。
Through comparing the change of SO 2 , NO2 , PM10 daily average concentration , monthly average concentration and annual concentration in the heating period of 2011 to 2013 in Urumiqi, the tendency of change of Urumiqi atmosphere environ-ment before and after the changing fuel coal to natural gas project was analyzed .It is proved that the changing fuel coal to nat-ural gas project in Urumqi can improve city atmospheric environment , and this project is a reliable basis for the promotion and development of the engineering in future .
