Abstract:
Nine typical plant communities in Olympic Forest Park as objects were studied using long-term fixed-point monitoring method to analyze the seasonal and annual PM2.5 removal percentage by different plant disposition.The partial correlations between the removal percentage and the structure indicators of green spaces were also studied.It aimed to provide a quantitative reference for optimizing the plant community structure and improving the function of urban green space to control PM2.5.The results indicated that the purification ability of lawn with few trees to PM2.5 was significantly lower than that of woodland；PM2.5 removal percentage of mixed broadleaf-conifer forest was larger than that of broad-leaved forest and coniferous forest.ρ(PM2.5)reduction rate of green space had the significantly positive correlations with the diameter at tree′s breast height，and the insignificant positive correlations with plant height and crown width.The stand with too large density or crown density could lead to a rise in PM2.5 concentrations in green space.
