中文摘要	利用地基多轴差分吸收光谱仪(MAX-DOAS),选择新疆开孔河流域绿洲城市库尔勒为研究区,于2014-2016年对其市区及郊区的对流层NO_2垂直柱浓度(VCD)进行观测,结果表明:(1)从日变化来看,市区在不同季节的NO_2 VCD日均值为冬季>秋季>春季>夏季,郊区为冬季>春季>秋季>夏季。(2)从季节变化来看,市区和郊区的NO_2 VCD波峰均出现在冬季,波谷基本出现在夏季;NO_2 VCD的年均值在2014年最高,2015年有所下降,2016年又开始回升。(3)NO_2 VCD与同期NO_2地面浓度变化趋势基本一致,两者相关性良好(R=0.795)。(4)地形与风向影响使得库尔勒污染物不断向郊区扩散,造成郊区NO_2浓度的增加;冬季漫长的采暖期、风沙天气频发以及不利于污染物扩散的静稳天气条件导致污染物的聚集,难以及时扩散。
英文摘要	The tropospheric NO_2 vertical column densities (VCD) in both urban and suburban areas in Korla,an oasis city in the Kaikong River Basin of Xinjiang,were observed from 2014-2016 using ground-based multi-axis differential absorption spectrometer (MAX-DOAS). The results showed that:(1) the average daily NO_2 VCD values in urban areas were highest in winter,followed by autumn,spring,and summer,and in the suburbs they were highest in winter,followed by spring,autumn,and summer. (2) The highest seasonal NO_2 VCD observed in both urban and suburban areas occurred in winter,whereas the lowest values occurred in summer. The average annual value of NO_2 VCD was highest in 2014. It showed a decline in 2015,and began rising again in 2016. (3) NO_2 VCD was consistent and fairly well correlated to ground NO_2 concentrations in the same period (R=0.795). (4) The influence of topography and wind direction made the pollutants continue to spread to the suburbs,resulting in an increase in the concentration of NO_2 in the suburbs. Then,long heating periods in winter,frequent occurrences of wind and sand,and static weather conditions,which were not conducive to the spread of pollutants,led to the accumulation of pollutants,resulting in an increase in NO_2 concentrations.
