探究塔里木河中下游气溶胶分布及变化特征，准确了解塔里木河中下游气溶胶对研究大气污染、应对全球气候变化是非常重要的，因此对2017—2019年的MODIS MAIAC气溶胶光学厚度数据从不同的时空尺度和气溶胶空间分布上分析塔里木河中下游气溶胶时空变化特征。结果表明：从年际尺度上看，1-5月AOD呈现持续上升趋势，5-12月AOD总体呈现下降趋势；从季节尺度上看，AOD季节变化呈春季整体高、夏季局部高、秋冬季略低的特点；在空间上，AOD呈现显著的西南高、东北低趋势特征。可进一步探究不同时空气溶胶分布特征，以期为塔里木河中下游环境污染治理提供更好的决策指导。
Abstract：Exploring the distribution and change characteristics of atmospheric aerosols in the middle and lower Tarim River is very important for studying atmospheric environment pollution and coping with global climate change. We used the MODIS MAIAC AOD data from 2017 to 2019 to analyze the spatio-temporal change characteristics of aerosol in the middle and lower Tarim River from different spatio-temporal scales and spatial distribution of aerosols. The results show that in the interannual scale, AOD shows a continuous upward trend from January to May,and AOD shows an overall downward trend from May to December. In the seasonal scale, the seasonal change of AOD is characterized by high overall in spring, partially high in summer and slightly low in autumn and winter. Spatially, AOD presents a significant trend of high in the southwest and low in the northeast. The distribution characteristics of AOD at different spatio-temporal can be further explored with a view to better decision-making guidance for environmental pollution control in the middle and lower Tarim River.
