Numerical study on adjusting and controlling effect of forest cover on PM10 and O3

A new-coupled air quality numerical modeling system has been developed and applied to the study on the adjusting and controlling effect of forest cover on air quality. The modeling system is composed of Plant Canopy Layer Model (PCLM), Urban Scale Meteorological Model (USMM), and High-Resolution Chemical Model (HRCM). The system was applied to the study on the ecological adjusting and controlling effects on PM10 and O3 in Jinan City, China. The results show that the forest cover can adjust and control PM10 and O3 significantly by reducing the concentrations of PM10 while increasing the concentrations of O3 with the increase of forest cover.
