新疆气溶胶时空变化特征及潜在源区分析
Analysis of Temporal and Spatial Variation Characteristics and Potential Source Areas of Aerosol in Xinjiang
摘要
Abstract
Aerosol Optical Depth(AOD)is one of the most important optical properties of aerosols,quantifying the concentration of aerosols,atmospheric turbidity,and fully reflecting the regional atmospheric pollution situation.Xinjiang is a typical arid and semi-arid region and a source area of aerosols,so the analysis of the temporal and spatial variation characteristics of AOD in Xinjiang can provide a theoretical basis for evaluating the quality of atmospheric environmental in Xinjiang,and further can lay a solid foundation for comprehensively promoting the construction of beautiful Xinjiang.Based on the AOD data of MAIAC,combined with the backward trajectory model,potential source contribution function and concentration weighted trajectory analysis methods,the spatial and temporal heterogeneity of AOD in Xinjiang from 2000 to 2022 was systematically analyzed,and the distribution characteristics of the potential source areas of aerosols in different regions of Xinjiang were explored in detail.The results showed that since 2000,the AOD value in Xinjiang reached its peak in 2014,and the lowest value occurred in 2017.The AOD value in southern Xinjiang was always higher than that in eastern and northern Xinjiang.From the perspective of spatial distribution,the AOD in southern Xinjiang was the highest,followed by eastern Xinjiang,and the northern Xinjiang was the lowest.The high-value areas of AOD in southern Xinjiang were mostly concentrated in the Taklamakan Desert and surrounding oasis areas.In terms of potential source areas,the potential source areas of AOD in typical cities of southernXinjiang,northernXinjiang and eastern Xinjiang were mainly in the north,northwest,and southeast,respectively.关键词
