摘要
城市气溶胶光学厚度的研究对区域性大气污染的防治有重要作用,文章以GIS为平台,探讨了德州市2012年(采暖季、风沙季和非采暖季)气溶胶光学厚度的时空分布特征以及AOD与近地面颗粒物浓度的关系。结果表明:2012年德州市气溶胶光学厚度时间变化趋势为风沙季>采暖季>非采暖季,采用提出的能见度大气总订正因子,能使修正后的TSP、PM10、PM2.5与AOD的线性相关系数分别达到0.714、0.649和0.657,在二次回归方程中相关系数分别达到了0.727、0.701和0.686。
The study on urban aerosol optical depth plays an important role in controlling the regional air pollution. We research the temporal and spatial distribution of the aerosol optical depth over Dezhou based on GIS platform in 2012 （heating season, windy season and non-heating season）. The results show that the time of aerosol optical depth trend follows the order of windy season 〉 heating season 〉 non-heating season; applying the visibility correction factor which can improve the linear correlation between TSP, PM10, PM2.5 and AOD to attain 0.714, O. 649 and 0.657 respectively; besides, the correlation coefficients in quadratic regression equations reach to 0. 727, 0. 701 and 0.686 respectively.
