中文摘要	基于地基多轴差分吸收光谱技术(multi-axis different optical absorption spectroscopy,MAX-DOAS),分析位于中国西部边陲的典型干旱区城市博乐市大气对流层NO_2垂直柱浓度(vertical column densities,VCD)分布、变化,了解其变化规律和分布特点。结果表明:(1)博乐市不同观测点对流层NO_2 VCD高低表现为农田区>市区,农田区NO_2浓度最大达到5.691015 molec/cm~2,市区NO_2浓度最大达到3.791015 molec/cm~2;(2)市区观测点对流层NO_2浓度变化趋势基本一致,相同的是北京时间10:00,出现峰值;农田区观测点对流层NO_2 VCD一天内呈现缓慢上升趋势;(3)同一区域,不同天气条件下,对流层NO_2 VCD高低不同。多云条件下对流层NO_2 VCD浓度最高,其次是多云转阵雨、多云转小雨,晴天条件下对流层NO_2浓度较低;(4)不同区域,相同天气条件下对流层NO_2 VCD分布不同。社会活动较多的市区对流层NO_2 VCD较高。
英文摘要	Based on ground multi -axis different optical absorption spectroscopy technology,tropospheric atmospheric concentrations of NO_2 vertical column were analyzed in Bole City,a typical city in the arid area in the western region of China,to understand the variation and distribution characteristics. Results show different observation sites with a different tropospheric NO_2 VCD,a maximum of 5.691015 molecules/cm~2 NO_2 in the farmland area while 3.791015 molecules/cm~2 in the urban area. The change trend of troposphere NO_2 VCD is almost the same in the urban observation site,with a peak at 10:00 BJT,while the tropospheric NO_2 VCD concentration over farmland area within a day showed a trend of slowly rising. The tropospheric NO_2 VCD is different at different weather conditions in the same area,the tropospheric NO_2 VCD is the highest,followed by the cloudy turns shower,the cloudy turns light rain,and the minimum is at the clear day. The tropospheric NO_2 VCD distribution is different with the same weather conditions at different regions,higher in the urban areas where there are more human activities.
