为了解新疆阜康地区秋季NOx和O3浓度特征及其可能的影响要素,利用2009和2010年10月1日至11月31日新疆阜康市NOx和O3的观测资料,对阜康地区NOx和O3的变化特征及影响因素进行了分析。结果表明,2 a秋季NO、NO2、NOx、O3和Ox（Ox=NO2＋O3）的日均浓度最大值分别为27.2 ppb、33.0 ppb、60.2 ppb、25.4 ppb和36.0 ppb。采暖期NOx浓度显著高于非采暖期,2009年采暖期NO、NO2和NOx浓度分别比非采暖期上升了167%、49%和68%;2010年采暖期上升144%、69%和109%。秋季NOx月均浓度呈逐月上升趋势,而O3呈逐月下降趋势。NOx日均值超标率为4%（标准为国家一级标准）。污染物日变化分析表明,采暖期和非采暖期NOx浓度日变化型均为单峰型,峰值出现在上午;O3和Ox日变化也为单峰型,但峰值出现在午后最高温度出现的时段内。非采暖期O3和Ox日较差明显大于采暖期,温度和相对湿度是影响阜康区域O3浓度的重要气象因素。区域的空气质量受天气条件的影响,连续稳定的冷高压控制,近地面风力微弱以及持续的区域性大气下沉运动,以及来自周边区域的污染物的持续输送,容易形成污染过程。

英文摘要：

The variation characteristics and influencing factors of NOx and 03 concentration in Fukang area of Xinjiang were analyzed based on observations from 1 October to 31 November in 2009 and 2010. The results show that the daily average maximum concentra- tion of NO, NO2, NOx, 03 and Ox were 27.2 ppb, 33.0 ppb, 60.2 ppb, 25.4 ppb and 36.0 pph, respectively. The concentration of NOx during the heating period was significantly higher than that in non heating period, the average concentration of NO, NO2 and NOx during the heating period of 2009 increased by 167%, 49% and 68% compared with those in non heating period, and in 2010 in- creased by 144%, 69% and 109% , respectively. Monthly average concentration of NOx presented ascent trend while ozone concentra- tion decreased month by month in autumn. Daily average concentration of NOx exceeded 4% compared with the National Ambient Air Quality Standard. The diurnal variation of NOx, 03 and Ox concentration both in heating and non heating period presented single peak variation, the peak value of NOx occurred in the morning, but for ozone and Ox, the maximum occurred in the afternoon when tempera- ture reached maximum value. The daily range of ozone and Ox concentration was obviously bigger during non heating period than those in heating period, and temperature and relative humidity play a key role in local ozone concentration in Fukang. Meteorological factors had a significant influence on regional air quality status, when under the sustained cold high control, weak wind near surface, sustained descent motion, and sustained pollutants transportion from circumjacent area, a pollution process would form easily.
