摘要： 选取辽阳市2018 年11 月—2020 年10 月期间24 个月的降尘数据进行了对比分析，发现辽阳市总体上是每年
的1 月份尘量最小，从功能区上看，清洁区的降尘反倒最高。对降尘分析方法做了改动，既可避免在分析过程中造成尘
粒的损失，又能提高效率。

Abstract: This paper selected the dust fall data of 24 months from November 2018 to October 2020 in Liaoyang City for comparative
analysis, and found that Liaoyang City as a whole had the smallest dust amount in January every year, but from the perspective
of functional areas, the dust fall in clean areas was the highest. The method of dust fall analysis was modified, which
could avoid the loss of dust particles in the analysis process and improve the efficiency.
