摘要

The data of 116 atmospheric dust monitoring points in Jinan from 2009 to 2012 were analyzed. The average annual atmospheric dustfall was maintained at 10.47 to 14.34 t.km~(_2).month~(-1), and the change was less than 15.14%. Within one year, the atmospheric dustfall was mainly concentrated in the spring season (March to May), accounting for 27.72% to 33.44% of the annual dustfall. The lowest dustfall was concentrated in September to November. The dustfall in Jinan City was generally in a decreasing trend. The dustfall of each district is different from one another, the arrangement of 6 districts in Jinan is Huaiyin> Tianqiao Shizhong> Licheng> Lixia>Changqing. Special meteorological and ecological environment are the mainly factors to influence temporal and spatial distribution of the dustfall in Jinan.
