中文摘要	基于地基多轴差分吸收光谱仪(MAX-DOAS),分析2014年3月至2016年2月新疆干旱区城市(中等城市库尔勒市和小城市博乐市)对流层NO_2垂直柱浓度(VCD)变化规律、分布特征及其影响因素。结果表明:(1)新疆干旱区城市对流层NO_2 VCD采暖期是非采暖期的4倍左右,且有显著的季节特征,表现为冬季>秋季>春季>夏季,库尔勒市的对流层N02 VCD年均值大于博乐市,两市对流层NO_2 VCD日变化峰值在8:00(冬季峰值在9:00)和20:00左右,且晚上的峰值高于早上;(2)库尔勒市和博乐市的对流层NO_2 VCD高值分别达到2.54010~(15)~4.45010~(15)、1.63010~(15)~2.62010~(15) molec/cm~2,高值区均集中在商业、工业区,对流层NO_2 VCD低值分别为2.30010~(14)~1.92010~(15)、6.000* 10~(14)~1.390* 10~(15) molec/cm~2,低值区均集中在居民区、学校周边;(3)库尔勒市和博乐市对流层NO_2 VCD对气象因子有不同程度的响应,其与气压呈正相关,与气温、相对湿度、云量和风速呈负相关。
英文摘要	The characteristics of tropospheric NO_2 vertical column density (VCD) in arid area city of Xinjiang(medium city Korla and small city Bole) and its influence factors in March 2014 to February 2016 were analyzed according to the data monitored by ground-based multi-axis differential absorption spectrometer (MAX-DOAS). The results showed that: (1) the tropospheric NO_2 VCD during heating period was about 4 times of that during the period without heating and the significant seasonal feature ranked winter>autumn>spring>summer. The tropospheric N02 VCD annual value of Korla was higher than Bole. The daily variation had two peak values at 8:00 (9:00 for winter) and 20:00,with the night peak higher than morning peak. (2) The high values of tropospheric NO_2 VCD were 2.540* 10~(15)-4.450* 10~(15),1.63010~(15)-2.620 10~(15) molec/cm~2 for Korla and Bole, respectively, which were distributed on commerical and industrial area. The low values of tropospheric NO_2 VCD were 2.300 * 10~(14)-1.920 * 10~(15), 6.000* 10~(14)-1.390* 10~(15) molec/cm~2 for Korla and Bole,respectively,which were distributed on school and residential area. (3) The tropospheric N02 VCD had different degree of response to meteorological elements, with air pressure positively correlated to tropospheric NO_2 VCD, air temperature,relative humidity, cloud cover and wind speed negatively correlated to tropospheric N02 VCD.
