北京不同树种吸滞PM2.5特征研究
Characteristics of PM2.5 Absorption of 6 Tree Species and Its Relationship with Atmospheric PM2.5 Concentration in Beijing
摘要
Abstract
In order to explore the variation of PM2.5 adsorption on the leaves of green tree species in different regions and their relationship with PM2.5 mass concentration,the six common tree species of Beijing city were used as the research object and PM2.5 adsorption capacity and its mass concentration were determined respectively in different regions.The results showed that PM2.5 of different tree species adsorption capacity of per unit leaf area were obviously different.And the PM2.5 adsorption capacity of leaves tended to decrease from suburban to urban.There was significant correlation between the PM2.5 adsorption of leaves and PM2.5 concentration in the atmosphere,especially the Salix babylonica (p＜0.05),Populus (p＜0.05) and Pinustabuliformis (p＜0.01);PM2.5 concentration in different areas decreased in the order of Xishan Forest Park (108.238 μg/m3),Songshan Nature Reserve (80.522 μg/m3),Beijing Botanical Garden (76.905 μg/m3),Nanhaizi Park (74.153 μg/m3).The PM2.5 adsorption capacity in tree species increased along with the increase of air pollution.关键词
