  • 摘要: 随着城市化和工业化的发展，空气环境问题日益突出，大气颗粒物污染受到人们越来越多的关注.为了研究城市道路中不同绿地结构对大气不同粒径颗粒物的消减作用，本文选择青岛市城阳区主干道——长城路的4种不同绿地结构（“乔-灌-草”、“乔-草”、“乔-灌”、“灌-草”），测定其对不同粒径颗粒物（PM10、PM2.5、PM1）的消减率.结果表明：（1）不同粒径颗粒物的浓度日变化曲线呈现出“早晚高，中午低”的变化趋势，其中8：00-10：00的颗粒物浓度最高；颗粒物浓度日变化与空气湿度变化相一致，与温度变化相反；（2）4种绿地结构对PM10的消减率表现为“乔-灌-草” > “乔-灌” > “灌-草” > “乔-草”，对PM2.5和PM1的消减率表现为“乔-灌-草” > “乔-灌” > “乔-草” > “灌-草”；且各绿地结构对PM2.5的消减能力最强，其次为PM1和PM10；（3）同一种绿地结构，植物种类越丰富，其消减大气颗粒物的能力越强.
    Abstract: With the development of urbanization and industrialization, air pollution is becoming increasing serious, and the air particulate matter pollution has received increased attention. In order to investigute the subduction effect of different green space structures on atmospheric particulate matter, four types of green space structures ("arbor-shrub-grass", "arbor-shrub", "arbor-grass", "shrub-grass") on Changcheng road, the main road in Chengyang District of Qingdao City was chosen to measure the different diameter particulate matter (PM10, PM2.5 and PM1) subduction rates. The results showed that the diurnal variation of particulate matter concentration displayed a patlem of "high at night and in the morning and low at moon", and the highest concentration of particulate matter occured between 8:00-10:00 am. Daily variation of particulate matter concentration was consistent with the change of the air humidity and correlated inversely with temperature. The subduction rates of the four types of green space structures for PM10 were "arbor-shrub-grass" > "arbor-shrub" > "shrub-grass" > "arbor-grass", and were "arbor-shrub-grass" > "arbor-shrub" > "arbor-grass" > "shrub-grass" for both PM2.5 and PM1. The subduction ability of each green space structure on PM2.5 was the strongest, followed by PM1 and PM10. For a particular type of green space structure, the more plant species it has, the stronger subduction ability it will have.
