Since the State Council began to implement the Air Quality Improvement Action Plan in 2013, the air quality in China has been comprehensively improved. However, ozone (O3) pollution has become prominent. Due to the nonlinear influences of meteorology and precursors, the response relationship between the evolution trend of O3 and the change in emissions varies in different regions of Hangzhou. Separating the impacts of meteorology and emissions on the evolution of O3 pollution and evaluating the management and control effectiveness of emission reduction measures are of great significance for formulating precise prevention and control policies.This paper utilizes the observational data of 15 monitoring stations in Hangzhou during the warm seasons from 2014 to 2023, comprehensively analyzes the urban and rural evolution laws of multiple indicators related to O3, and adopts the de-meteorological method based on the random forest algorithm to separate the respective contributions of meteorology and emissions in the long-term evolution trend of O3, so as to quantitatively evaluate the effect of O3 pollution control.The results show that the annual growth rates of MDA8 O3 and Ox in Hangzhou as a whole are 1.4 μg/m3/yr and 0.07 μg/m3/yr respectively. Among them, the increase range and concentration values in urban areas are significantly higher than those in rural areas. The differences in O3 and Ox between urban and rural areas in Hangzhou continue to increase, and the reduction of NOx emissions has failed to effectively suppress the rise of ozone. Since 2018, meteorological conditions have changed from being unfavorable to favorable for ozone generation, which is most significant in May and September, the months with the most serious pollution. In the overall interannual upward trend of O3, 64% is caused by meteorological conditions, and the rest is due to ineffective management and control. After excluding the influence of meteorology, long-term management and control measures have effectively reduced the atmospheric Oxidation capacity in both urban and rural areas and curbed the increase in O3 concentration in rural areas. However, there has been no effect on the control of O3 in urban areas and local photochemical generation. The above results indicate that continuing to strengthen anthropogenic control measures under unfavorable meteorological conditions (focusing on May and September) is key to suppressing ozone pollution in Hangzhou.
