摘　　要：为研究城市道路不同植物配置模式对大气中PM2.5和PM10浓度的削减作用,以郑州市建设路为研究对象,选取4种乔-灌型植物配置,采用便携式颗粒物检测仪器(CW-HAT200S)及气象仪(Kestrel 5000)测定其PM2.5、PM10浓度和气象因子,分析乔-灌型植物群落对PM2.5和PM10浓度在垂直空间和水平空间的削减作用。结果表明,道路环境下PM2.5和PM10浓度在垂直方向和水平方向的日动态变化规律表现较为一致,均呈“U”型,早晚高,中午低;颗粒物浓度与温度、风速呈显著负相关,与湿度呈显著正相关;削减率与温度、风速和湿度的相关关系不明显。乔木枝下高较低、有多层高度的配置形式对颗粒物的削减更有效果,群落配置“美人梅+红叶石楠+黄杨”在垂直方向上削减效果最好,群落配置“悬铃木+海桐+构骨”在水平方向上削减效果最好。The objective of this study was to explore the effect of different plant configurations methods on reducing the concentration of PM 2.5 and PM 10 in the atmosphere.Four types of arbor-shrub plant configurations in Jianshe Road of Zhengzhou were selected to detect the PM 2.5 and PM 10 concentrations and meteorological factors by PMs samplers(CW-HAT200S)and a portable weather station(Kestrel 5000),and to analyze reduction of arbor-shrub plant community in vertical space and horizontal space.The results showed that under the road traffic environment,the diurnal dynamic changes of PM 2.5 and PM 10 concentrations in the vertical and horizontal directions were relatively consistent,showing a“U”shape,higher in the morning and evening and lower at noon;the particulate matter concentrations had a significant negative correlation with temperature and wind speed,and a significant positive correlation with humidity;the correlation between reduction rate and temperature,wind speed and humidity were not obvious.The configuration with low height under the branches and multi-layer height was more effective for the reduction of particulate matter.In this experiment,the configuration of“Prunus×blireana‘Meiren’+Photinia serrulata+Buxus sinica”had a better reduction effect in the vertical direction,and the configuration of“Platanus orientalis+Pittosporum tobira+Ilex cornuta”had a better reduction effect in the horizontal direction.
