中文摘要	为探讨天山北坡河谷绿洲城市车流量与对流层NO_2垂直柱浓度(VCD)的关系,基于各城市车流量状况,利用地基多轴差分光谱仪(Mini MAX-DOAS)在2018年-2019年天山北坡经济带上的综合性大城市乌鲁木齐、工业型中等城市石河子和工业型小城市阜康市中心区连续固定监测,并沿城市交通主干道进行车载移动监测,研究车流量对NO_2VCD的影响,对比分析山盆体系河谷绿洲城市与中东部发达城市污染严重原因的差异。结果表明:(1)天山北坡大中小城市的车流量日均值大城市乌鲁木齐(1 406辆/5min)远大于中小城市,中等城市石河子(203辆/5min)和小城市阜康(185辆/5min)差异并不显著(p>0.05),而各类城市NO_2VCD整体差异显著(p<0.05),其日变化峰值有所差异,表现为乌鲁木齐(22.61310~(15) molec·cm~(-2))>阜康(17.75810~(15) molec·cm~(-2))>石河子(15.272*10~(15) molec·cm~(-2)),三类城市的车流量和NO_2VCD的日变化趋势一致,都呈现出"早晚高,中午低"的变化趋势;季节变化中三类城市的车流量和NO_2VCD均为:冬春季>秋夏季;(2)虽然早晚各监测点的车流量有所差异,但三类城市的车流都集中在市中心附近;移动监测数据表明,NO_2VCD高值出现在车流较高的市区,并且在各城市风向稳定时,下风向浓度大于上风向;由于居住空间差异,人们在城市各功能区间的活动,车辆流向和NO_2VCD都集中于人流密集的商业区,说明车辆对NO_2VCD具有较大贡献;(3)2009年-2019年10年间天山北坡大中小城市经济生产总值增长率在200%以上,乌鲁木齐、石河子机动车增长率超过北京、上海等发达城市,城市快速发展,并处于河谷绿洲地带,地势南高北低,冬季逆温层深厚,静风天数较多,采暖期长达6个月,造成冬季污染严重。天山北坡城市除人为污染排放外,自然因素对污染物形成聚集作用。
英文摘要	Inquiring into the northern region of Tianshan Mountain valley oasis,urban traffic and the link between tropospheric NO_2vertical column density,Employing ground-based multi-axis difference spectrometer,(Mini MAX-DOAS)in 2018-2019,the north slope of Tianshan Mountains,economic belt comprehensive city Urumqi,Shihezi and in addition,medium-sized city,small continuous fixed monitoring Fukang city downtown area,carrying on the vehicle-mounted mobile monitoring on the city traffic trunk road,based on the urban traffic condition.Studying the influence of the tropospheric NO_2vertical column density,and analysis of mountain valley oasis city with developed cities of middle basin system's pollution differences.The results show that:(1)Medium cities of the north slope of Tianshan Mountain cities of daily mean value flow in Urumqi(1 406/5min)greater than the small and medium-sized cities,medium-sized city Shihezi(203/5min)and the small city Fukang(185/5min),there is no significant difference(p>0.05),and all kinds of city NO_2VCD overall significant difference(p<0.05),the daily variation of the peak,Urumqi(22.61310~(15) molec·cm~(-2))>Fukang (17.75810~(15) molec·cm~(-2))>Shihezi(15.272*10~(15) molec·cm~(-2)).The daily variation trend of traffic flow and NO_2VCD in the three cities is consistent,showing a trend of"high in the morning and evening,low at noon".In the seasonal variation,the traffic flow and NO_2VCD of the three types of cities are:winter and spring>autumn and summer;(2)Although the traffic flow at the monitoring points in the morning and evening is different,the traffic flow of the three types of cities is concentrated near the city center;The movement monitoring data show that the high NO_2VCD value occurs in urban areas with high traffic flow,and when the wind direction is stable in each city,the downwind concentration is greater than the upwind concentration.Due to the differences of living space,people's activities in various functional areas of the city,traffic flow and NO_2VCD are concentrated in the commercial district with dense population,indicating that vehicles have a great contribution to NO_2VCD;(3)2009-2019,ten years north slope of Tianshan Mountain medium cities economic growth rate of GDP over 200%,Urumqi,Shihezi motor vehicle growth rate than developed cities such as Beijing,Shanghai,rapid urban development,and in the valley oasis area,low meteorological terrain north,the winter inversion layer,deep calm wind days more,heating period 6 months long,causing serious pollution in winter.In addition to the anthropogenic pollution discharge,natural factors contribute to the accumulation of pollutants in the north slope of Tianshan Mountain.
