Abstract Regional air pollution is a multifaceted and dynamic system, rendering linear statistical approaches insufficient in capturing its inherent patterns of variability, particularly the intricate spatiotemporal fluctuations multiple indicators. Therefore, this study examines synergistic evolution impact mechanisms PM2.5 O3 four cities China’s Yangtze River Delta base from 2013 to 2022 by complex systems theory. Initially, multifractality long-term persistence between are confirmed each city using Multifractal Detrended Cross-Correlation Analysis (MFDCCA). Subsequently, evaluation indicators established assess control effects. Furthermore, factors influencing coordinated analyzed Ensemble Empirical Mode Decomposition (EEMD). Finally, Self-Organized Criticality (SOC) theory introduced understand concentration patterns. The results indicate: (1) Multifractality exist cities, strengthens with implementation atmospheric prevention policies. application facilitates explanation quantification effectiveness O3. (2) Since 2013, except for Nanjing, effects Shanghai, Hangzhou, Suzhou have been unsatisfactory not effectively improved. (3) Compared human activities, measures, periodic meteorological variations, long-range transport regional pollutants greater influence on regulation (4) SOC may be primary mechanism O3, sudden events such as epidemic measures can disrupt existing balance thereby reducing

Urban trees are known for their ability to settle fine particulate matter (PM2.5), yet the effects of historical pollution exposure on dust-retention capacity and stress memory remain underexplored. Therefore, we selected Euonymus japonicus Thunb. var. aurea-marginatus Hort. Photinia × fraseri Dress, which two common urban greening tree species in Yangtze River Delta, a highly urbanized region China facing severe air challenges, characterized by dense forests, employed an aerosol generator perform controlled experiments aiming simulate PM2.5 sealed chamber. The encompassed first treatment period P1 (15 days), recovery R second P2 days). study investigates impacts simulating environmental conditions assessing morphological physiological changes trees. main results as follows: Vd significantly decreased 10th day during compared with that same P1, whereas Dress 15th day. Compared those specific leaf area both plants decreased, weight increased, wax layer thickened, stomata content photosynthetic pigments remained stable P2. Furthermore, tolerance index (APTI) generally increased This contributes international knowledge examining underscores role enhancing plant resistance periodic pollution, offering insights into adaptive mechanisms can be applied globally, not just regionally.

Global climate change and rapid urbanization have brought unprecedented environmental challenges, especially in rapidly expanding cities like Xi’an, posing potential challenges to sustainable development if not accompanied by adequate greenery, thoughtful layouts, pollution control measures. The increasing frequency intensity of urban air (e.g., PM2.5, PM10, O3) extreme events heatwaves) heightened health risks for residents. Existing studies mostly focus on single or factors, neglecting the compounded effects these factors. To fill this research gap, study presents a risk assessment model, specifically analyzing heatwaves pollution. By integrating hazard, exposure, vulnerability factors using entropy weight–TOPSIS method, results reveal significant spatial differences across various regions Xi’an. findings provide valuable guidance planners policymakers better address hazards, reduce risks, promote development.
