| 中文摘要: |
| 采用OMI 传感器的气溶胶产品，分析了2006—2015年中国西部城市天水市对流层紫外吸收性气溶胶的时空分布特征。结果表明：空间上，十年间天水市的吸收性气溶胶表现出从中部向周围依次减弱的南北向带状分布规律；季节变化呈现出秋冬季高于春夏季的规律；时间上，吸收性气溶胶指数（AI）从2006年的0.075增至2015年的0.506，年均值为 0.28，年均增长率为57.5%；十年间出现2次阶段性增长和2次阶段性减小；AI年际变化与天水市地方总产值相关性为 0.902，第一产业对其影响最大，第三产业影响最小。 |

| The temporal and spatial distribution characteristics of the tropospheric UV absorbing aerosols in Tianshui, western China from 2006 to 2015 were analyzed based on the remote sensing data from OMI satellite sensor. The results showed that the spatial distribution of absorbing aerosols in Tianshui tended to decrease from the centre to around, with a north south zonal distribution. The seasonal variation showed the level in autumn and winter were higher than that in spring and summer. The aerosol index increased from 0.075 in 2006 to 0.506 in 2015, with an annual average of 0.28 and an average annual growth rate of 57.5%. There were two stages increase and two stages decrease during 10 years. The correlation coefficient between the local GDP and the aerosol index was 0.902. The primary industry had the most impact, while the tertiary industry had the minimum. |
