To evaluate the impact of air pollution prevention and control policies on the spatiotemporal evolution of Ozone (O3) and fine particulate matter (PM2.5), this study analyzed the spatiotemporal stratified heterogeneity of O3 and PM2.5 pollution across 331 Chinese cities from 2014 to 2024 using a Bayesian spatiotemporal hierarchical model. The GeoDetector model was further employed to quantify the determinant power and interactive effects of meteorological, socioeconomic, and other pollutant factors on summer O3 and winter PM2.5 pollution during the implementation of three key policies: the Air Pollution Prevention and Control Action Plan (2014~2017), the Blue Sky Defense Action Plan (2018~2020), and a circular on further Promoting the Nationwide Battle to Prevent and Control Pollution (2021~2024). The results indicate that O3 concentration exhibited a trend of initial rapid growth followed by a slower rate, with hotspots mainly distributed in North China and the Yangtze River Delta (YRD). Conversely, PM2.5 concentration continuously decreased, and high-value areas shrank and concentrated in North China, the YRD, and the Chengdu-Chongqing region. A positive correlation between O3 and PM2.5 was frequently observed in the southern and northeastern humid regions, whereas a negative correlation prevailed in the northwestern semi-arid areas. Although the dominant factors for O3 and PM2.5 evolved across policy stages, the determinant power of the interactions among different factors were consistently stronger than that of individual factors. Specifically, from 2014 to 2017, O3 was mainly affected by maximum temperature (Geo_q=0.24), industrial output (Geo_q=0.22), and PM10 (Geo_q = 0.60); PM2.5 was primarily affected by maximum temperature (Geo_q = 0.41), population density (Geo_q= 0.40), and PM10 (Geo_q = 0.88). From 2018 to 2020, the dominant factors for O3 shifted to precipitation, population density, and PM10, while those for PM2.5 shifted to average temperature, population density, and PM10. From 2021 to 2024, the dominant factors for both shifted toward average temperature, population density, and PM10, albeit with significant differences in their determinant power. This research reveals the dynamic evolution of the spatiotemporal patterns of O3 and PM2.5 pollution driven by policies implementation, emphasizing the dominant role of multi-factor interactions in the composite pollution formation process. The findings provide a crucial scientific basis for formulating regionalized and phased synergistic control strategies for O3 and PM2.5.

为评估大气污染防治政策对O3和PM2.5时空演变的影响,基于贝叶斯时空层次模型分析了2014~2024年中国331个城市O3和PM2.5污染的时空分异特征,并利用地理探测器量化了《大气污染防治行动计划》、《打赢蓝天保卫战三年行动计划》和《关于深入打好污染防治攻坚战的意见》政策实施期间气象、社会经济及其他污染物因素对夏季O3和冬季PM2.5污染的主导作用.结果表明,O3浓度呈现增速由快到慢的变化趋势,热点区主要分布在华北和长三角地区;PM2.5浓度则持续下降,高值区收缩并集中在华北、长三角和成渝地区.O3和PM2.5在南方及东北湿润地区多呈正相关,在西北半干旱地区多呈负相关.尽管O3和PM2.5的主导因素随政策阶段演变,但不同因素间的交互作用对O3和PM2.5的解释力始终强于单一因素的作用.2014~2017年,O3主要受最高温度(Geo_q = 0.24)、工业产值(Geo_q = 0.22)、PM10(Geo_q = 0.60)影响;PM2.5主要受最高温度(Geo_q = 0.41)、人口密度(Geo_q = 0.40)、PM10(Geo_q = 0.88)影响.2018~2020年,O3主导因素转变为降水、人口密度、PM10;PM2.5主导因素转变为平均温度、人口密度、PM10.2021~2024年二者主导因素转变为平均温度、人口密度和PM10,但解释力有明显差异.研究揭示了政策驱动下O3与PM2.5污染时空格局的动态演变,强调了多因素交互作用在复合污染形成过程中的主导作用,为制定分区、分阶段的O3与PM2.5协同控制策略提供了依据.

为评估大气污染防治政策对O3和PM2.5时空演变的影响,基于贝叶斯时空层次模型分析了2014~2024年中国331个城市O3和PM2.5污染的时空分异特征,并利用地理探测器量化了《大气污染防治行动计划》、《打赢蓝天保卫战三年行动计划》和《关于深入打好污染防治攻坚战的意见》政策实施期间气象、社会经济及其他污染物因素对夏季O3和冬季PM2.5污染的主导作用.结果表明,O3浓度呈现增速由快到慢的变化趋势,热点区主要分布在华北和长三角地区;PM2.5浓度则持续下降,高值区收缩并集中在华北、长三角和成渝地区.O3和PM2.5在南方及东北湿润地区多呈正相关,在西北半干旱地区多呈负相关.尽管O3和PM2.5的主导因素随政策阶段演变,但不同因素间的交互作用对O3和PM2.5的解释力始终强于单一因素的作用.2014~2017年,O3主要受最高温度(Geo_q = 0.24)、工业产值(Geo_q = 0.22)、PM10(Geo_q = 0.60)影响;PM2.5主要受最高温度(Geo_q = 0.41)、人口密度(Geo_q = 0.40)、PM10(Geo_q = 0.88)影响.2018~2020年,O3主导因素转变为降水、人口密度、PM10;PM2.5主导因素转变为平均温度、人口密度、PM10.2021~2024年二者主导因素转变为平均温度、人口密度和PM10,但解释力有明显差异.研究揭示了政策驱动下O3与PM2.5污染时空格局的动态演变,强调了多因素交互作用在复合污染形成过程中的主导作用,为制定分区、分阶段的O3与PM2.5协同控制策略提供了依据.

To evaluate the impact of air pollution prevention and control policies on the spatiotemporal evolution of Ozone (O3) and fine particulate matter (PM2.5), this study analyzed the spatiotemporal stratified heterogeneity of O3 and PM2.5 pollution across 331 Chinese cities from 2014 to 2024 using a Bayesian spatiotemporal hierarchical model. The GeoDetector model was further employed to quantify the determinant power and interactive effects of meteorological, socioeconomic, and other pollutant factors on summer O3 and winter PM2.5 pollution during the implementation of three key policies: the Air Pollution Prevention and Control Action Plan (2014~2017), the Blue Sky Defense Action Plan (2018~2020), and a circular on further Promoting the Nationwide Battle to Prevent and Control Pollution (2021~2024). The results indicate that O3 concentration exhibited a trend of initial rapid growth followed by a slower rate, with hotspots mainly distributed in North China and the Yangtze River Delta (YRD). Conversely, PM2.5 concentration continuously decreased, and high-value areas shrank and concentrated in North China, the YRD, and the Chengdu-Chongqing region. A positive correlation between O3 and PM2.5 was frequently observed in the southern and northeastern humid regions, whereas a negative correlation prevailed in the northwestern semi-arid areas. Although the dominant factors for O3 and PM2.5 evolved across policy stages, the determinant power of the interactions among different factors were consistently stronger than that of individual factors. Specifically, from 2014 to 2017, O3 was mainly affected by maximum temperature (Geo_q=0.24), industrial output (Geo_q=0.22), and PM10 (Geo_q = 0.60); PM2.5 was primarily affected by maximum temperature (Geo_q = 0.41), population density (Geo_q= 0.40), and PM10 (Geo_q = 0.88). From 2018 to 2020, the dominant factors for O3 shifted to precipitation, population density, and PM10, while those for PM2.5 shifted to average temperature, population density, and PM10. From 2021 to 2024, the dominant factors for both shifted toward average temperature, population density, and PM10, albeit with significant differences in their determinant power. This research reveals the dynamic evolution of the spatiotemporal patterns of O3 and PM2.5 pollution driven by policies implementation, emphasizing the dominant role of multi-factor interactions in the composite pollution formation process. The findings provide a crucial scientific basis for formulating regionalized and phased synergistic control strategies for O3 and PM2.5.
