Overview

Field measurements reveal seasonal performance of plant communities to mitigate particulate matter in urban areas, indicating new greening strategies.

Key Points

  • Identify the most effective urban plant community for particulate matter removal across different seasons.
  • Conducted field measurements of ambient particulate matter concentrations across urban plant communities.
  • Quantitatively compared the PM removal efficiency of different community types using size-fractionated pollutants.
  • Evaluated species composition, canopy structure, and seasonal dynamics related to PM removal.
  • Evergreen broad-leaved forests showed the highest particulate matter removal efficiency.
  • PM removal efficacy decreases with smaller particle sizes, particularly for ultrafine particles like PM1.
  • Deciduous broad-leaved forests performed best in summer due to enhanced leaf area index and stomatal activity.
