摘　　要：以内蒙古包头市为研究区,以2015—2016年Landsat8 OLI和MOD09反射率产品为数据源,通过6S模型建立查找表,采用深蓝算法反演包头市气溶胶光学厚度(AOD)分布,并探讨其AOD分布特征。结果表明:2015年包头市夏季AOD水平最高,春、秋次之,冬季最低;区域AOD浓度高低与城市下垫面状态有关。本研究为进一步构建可持续的人居环境奠定基础。Baotou City was taken as the study area, Landsat8OLI and MOD09 surface reflectance product in 2015 was used to establish a lookup table by 6S model, the dark blue algorithm （DB） of aerosol optical thickness （AOD） was coined to explore its seasonal distribution. The results showed that the concentration of AOD in 2015 in summer was the highest than that in spring and autumn, and the lowest value was shown in winter, the AOD concentration of this city changed with the change of land cover types. This re- search might provide theoretical foundation for construction of sustainable human settlement environment by city mangers.
