摘　　要：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PM_(2.5)和PM_(10)浓度以及温度、湿度和风速等气象因子,分析不同植物群落PM_(2.5)、PM_(10)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PM_(2.5)和PM_(10)浓度日变化基本一致,呈早高晚低趋势。不同样地内PM_(2.5)和PM_(10)浓度均表现为秋冬季高,春夏季低;PM_(2.5)和PM_(10)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PM_(2.5)和PM_(10)的阻滞率较高。PM_(2.5)和PM_(10)浓度与温度、相对湿度、风速等气象因子间呈不同相关性,PM_(2.5)浓度与各气象因子的相关性高于PM_(10)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,PM_(2.5) and PM_(10) 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 PM_(2.5) and PM_(10) concentrations in different plant communities were analyzed,and their correlation with meteorological factors was studied.The research results indicated that the daily changes of PM_(2.5) and PM_(10) concentrations in different areas were basically consistent,showing a trend of high in the morning and low in the evening.The concentrations of PM_(2.5) and PM_(10) in different areas were high in autumn and winter,and low in spring and summer;the concentrations of PM_(2.5) and PM_(10) were in the order of lawn and square plots>shrub-herb and arbor-herb plots>arbor-shrub-herb and arbor-shrub plots;the ability of composite community green space to retain particulate matter dust was stronger than that of single community.The arbor-shrub-herb and arbor-shrub plots had higher resistance to PM_(2.5) and PM_(10) .The concentrations of PM_(2.5) and PM_(10) had different correlation with meteorological factors such as temperature,relative humidity,and wind speed.The correlation between PM_(2.5) concentration and meteorological factors was higher than that of PM_(10) concentration.The Digital Park was an open park adjacent to urban roads and suitable for planting plant communities with high canopy density and evergreen tree species.
