摘　　要：郊区是NO_2不可忽视的排放源。基于地基多轴差分吸收光谱技术(Multi-Axis Different Optical Absorption Spectroscopy,即MAX-DOAS),分析乌鲁木齐北部郊区(农业区)对流层NO_2垂直柱浓度(vertical column densities,即VCD)特征,以了解其变化规律和分布特点。研究表明:观测期间,每天NO_2柱浓度高度不同,但是每天的变化趋势基本相同,早上NO_2柱浓度比较高,11:00左右达到第1峰值;2017年3月3—16日NO_2平均柱浓度11.58×10^(15)molec/cm^2;5月8—19日的日变化趋势更显著,第1峰值出现在10:00左右,比3月份要早,NO_2柱浓度平均值为7.42×10^(15)molec/cm^2;3月份和5月份乌鲁木齐郊区(农业区)NO_2柱浓度变化整体趋势相当,符合双峰的变化,3月份NO_2柱浓度大于5月份NO_2柱浓度。Suburbs are the important emission sources of NO 2,which is not be ignored.Based on ground Multi-Axis Different Optical Absorption Spectroscopy,this research focused on the tropospheric atmospheric concentrations of NO 2 vertical column distribution(VCD)and changes over the suburban area and field of Urumqi City,studying its variation and distribution characteristics.The results showed that:concentrations of NO 2 vertical column distribution were different every day but it showed a close trend of variation,and it was higher in the morning,11:00 am witnesses the first maximum;it′s average read 11.58×10 15 molec/cm 2 from 3th to 16rd in March;the daily variation was more obvious,10:00 am witnesses the first maximum;it′s average read 7.42×10 15 molec/cm 2 from 8th to 19rd in May;the trend of variation in March and May were generally close to each other in the suburban area and agricultural area,which showed a dual maximum,and the NO 2 VCD was higher in March than that in May.
