中文摘要	基于地基多轴差分吸收光谱技术(Multi-axis different optical absorption spectroscopy,简称MAX-DOAS),分析位于天山南坡典型干旱区城市,库尔勒市大气对流层NO_2垂直柱浓度(Vertical column densities简称VCD)分布、变化,以了解其变化规律和分布特点。研究表明:(1)库尔勒不同观测点对流层NO_2VCD高低表现为,农田区>新市区>老城区,农田区NO_2浓度最大达到3.4010~(15)molec/cm~2。(2)市区观测点,新城区和老城区对流层NO_2浓度变化趋势基本一致,呈现V和U字形变化趋势,早上和晚间浓度较高,中午浓度较低,市区浓度变化范围分别为1.9110~(15)~4.0210~(15)、0.2210~(15)~4.59*10~(15)molec/cm~2。(3)农田呈现出与市区不同的变化趋势,农田观测区中午之前浓度较低,中午之后NO_2浓度呈现升高的趋势。
英文摘要	Based on ground multi -axis differential optical absorption spectroscopy (MAX -DOAS), the tropospheric atmospheric concentrations of NO_2 vertical column distribution,change over Korla City,south slope of Mount Tianshan,a typical city in the arid area in the western region of China were analyzed, to understand the variation and distribution characteristics.Results show that different observation sites with a different tropospheric NO_2 VCD in Korla City, farmland area > new town>old town, with the maximum in farmland area as 3.4010~(15) molec/cm~2. Urban observation sites, as well as the new and old town tropospheric NO_2 concentration showed a trend of V and U,with the concentration higher at morning and evening, lower concentration at noon,and the concentration of urban observation sites are in the range of 1.9110~(15)~4.02* 1015, 0.22 10~(15) ~4.59 10~(15) molec/cm~2 respectively. The trend of the farmland is different from the urban, with NO_2 concentration lower in the morning, then showing a trend of rising.
