摘要为验证城市空气污染物排放及协同控制后的周期性规律,利用小波变换对武汉市2013~2020年共计2421d的逐日PM_2.5、PM₁₀及臭氧浓度数据进行分析.结果表明:可吸入颗粒物污染情况逐年改善,PM_2.5浓度年均值由80.5μg/m³降至45.3μg/m³,超标比例由44%降至11%;PM₁₀浓度年均值由113.6μg/m³降至72.6μg/m³,超标比例由22%降至2%.臭氧污染未有明显改善,浓度年均值在90~100μg/m³间波动.PM_2.5、PM₁₀与臭氧浓度均表现出明显的周期性,PM_2.5浓度主周期300d、次周期140d左右;PM₁₀浓度主周期300d、次周期125d左右;臭氧浓度主周期300d、次周期143d左右.PM_2.5与PM₁₀的周期与位相均相似,表明武汉市PM_2.5与PM₁₀整体颗粒物污染行为更为一致;PM_2.5、PM₁₀与臭氧周期性相似,但位相有差异.0~64d左右的短周期内表现出正相关性;300d左右的长周期表现出负相关性.

Abstract：In order to verify the periodic law after the cooperative control of urban air pollutants emission, wavelet transform was used to analyse daily PM_2.5, PM₁₀ and ozone concentration data of 2421 days (d) from 2013 to 2020 in Wuhan. The results are as follows: Inhalable particulate matter pollution had been reduced year by year. From 2014 to 2019, the annual average concentration of PM_2.5 had reduced from 80.5μg/m³ to 45.3μg/m³, and that of PM₁₀ had reduced from 113.6μg/m³ to 72.6μg/m³, which means the excessive rate of PM_2.5 was reduced from 44% to 11%, and that of PM₁₀ was reduced from 22% to 2%. The ozone pollution had kept unabated, with the annual average concentration of ozone fluctuating between 90μg/m³ to 100μg/m³. The concentration of all three kinds of pollutants displayed clear periodicity. PM_2.5, PM₁₀ and ozone concentration displayed with a same primary period of 300d. On the contrary, the secondary period of the three pollutants were 140d, 125d, and 143d respectively. PM_2.5 and PM₁₀ had similar periods and phases, which indicates that pollution behaviours of both particulate matters are consistent. Furthermore, the concentration of the three pollutants had a positive correlation was revealed in short period (0~64d), whereas a negative correlation in long period of about 300d.
