中文摘要	为探讨天山南北绿洲城市夏季对流层NO_2浓度分布特征,基于MAX-DOAS于2015-2017(6-8月)连续固定监测和车载移动监测,并结合社会经济因素和气象因子,研究乌鲁木齐、博乐、库尔勒及和田的NO_2时空分布规律。结果表明:(1)天山北坡城市对流层NO_2浓度整体高于天山南坡城市,北坡乌鲁木齐(6.9010~(15) molec/cm~2)>南坡库尔勒(3.3410~(15) molec/cm~2)>北坡博乐(2.6810~(15) molec/cm~2)>南坡和田(2.601015 molec/cm2);(2)乌鲁木齐市区日变化呈现多峰值波浪型分布,郊区没有明显峰谷值,博乐市区呈现两峰一谷日变化,郊区属于单峰特征;库尔勒、和田日变化特征相似,市区与郊区均为双峰型,且夏季市区对流层平均浓度(4.4210~(15) molec/cm~2)>郊区(3.3310~(15) molec/cm~2);(3)车载DOAS研究发现,城市对流层NO_2在风向稳定具有较高风速的监测日下风向浓度通常高于上风向,车流量高的立交桥与道路交汇处容易出现高值;(4)因天山南北绿洲城市的城市规模和产业结构不同,气象因子的差别,是导致NO_2浓度差异的重要原因。
英文摘要	The purpose of this study was to investigate the characteristics of NO_2 in oasis city of Xinjiang, based on the multi axis differential optical absorption spectroscopy (MAX-DOAS) technology, using fixed system and mobile system from June to August, 2015 to 2017. Combined with socioeconomic factors and meteorological factors, the time-space distribution regularities of NO_2 in Urumqi, Bole, Korla and Hotan were analyzed. The result showed that cities on the north-facing slope of Tianshan have a higher overall tropospheric NO_2 concentration than those on the south-facing slope: Urumqi on the north-facing slope (6.90 * 10~(15) molec/cm~2) >Korla on the south-facing slope (3.34 * 10~(15) molec/cm~2) >Bole on the north-facing slope (2.6810~(15) molec/cm~2)>Hotan on the south-facing slope (2.6010~(15) molec/cm~2). The diurnal variation of NO_2 concentration in the Urumqi urban area shows amulti-peakwave distribution, while that in the suburban area does not have clear peaks and troughs. The urban area of Bole has an M-shaped diurnal variation, while the suburban area has a single peak. Korla and Hotan have similar diurnal variations, and both the urban and suburban areas present double peaks. In summer, the average tropospheric NO_2 concentration in the urban area (4.4210~(15) molec/cm~2) was greater than that in the suburban area (3.33 10~(15) molec/cm~2). The mobile DOAS study found that, when the urban tropospheric NO_2 was monitored under strong winds in a constant direction, tropospheric NO_2 concentrations are higher in the downwind than the upwind direction. The concentrations at overpasses and road intersections with high volumes of traffic are often higher. Differences in the size and industrial structures of oasis cities in the north and south of Tianshan, as well as their meteorological factors, are the main cause of varying NO_2 concentrations.
