| 以郑州市数码公园为例，研究不同植物群落对大气颗粒物污染的影响。2020年4月—2021年3月，监测郑州市数码公园内不同植物群落结构（乔灌草、乔草、乔灌、灌草、草坪）在春夏秋冬四季的PM2.5和PM10浓度以及温度、湿度和风速等气象因子，分析不同植物群落PM2.5、PM10浓度的变化规律，并研究其与气象因子的相关性。研究结果表明，不同样地内PM2.5和PM10浓度日变化基本一致，呈早高晚低趋势。不同样地内PM2.5和PM10浓度均表现为秋冬季高，春夏季低；PM2.5和PM10浓度高低依次为草坪和广场样地＞灌草和乔草结构样地＞乔灌草和乔灌结构样地；复合群落结构绿地对颗粒物滞尘能力大于单一群落结构。乔灌草、乔灌结构样地对PM2.5和PM10的阻滞率较高。PM2.5和PM10浓度与温度、相对湿度、风速等气象因子间呈不同相关性，PM2.5浓度与各气象因子的相关性高于PM10浓度。由于数码公园为紧邻城市道路的开放公园，适宜种植郁闭度较高、以常绿树种为主的植物群落类型。 |

| This paper investigated the influence of different plant communities on atmospheric particulate matter pollution based on the case of Zhengzhou Digital Park. From April 2020 to March 2021, PM2.5 and PM10 concentrations and meteorological factors such as temperature, humidity, and wind speed, were monitored for different plant communities (arbor-shrub-herb, arbor-herb, arbor-shrub, shrub-herb and lawn) in Zhengzhou Digital Park in the four seasons. The variation patterns of PM2.5 and PM10 concentrations in different plant communities were analyzed, and their correlation with meteorological factors was studied. The research results indicated that the daily changes of |
