北京不同树种吸滞PM2.5特征研究

以北京市6种常见树种为研究对象,测定不同园林绿化区PM2.5吸附量和质量浓度,探究绿化树种叶片在不同地区吸附PM2.5的变化规律及其与PM2.5质量浓度间关系。结果表明,不同树种叶片单位面积PM2.5吸附量差异显著,且在不同地点叶片吸附量变化规律基本表现为由“近郊—城区”逐渐下降,各树种叶片PM2.5的吸附量均与大气中PM2.5质量浓度呈正相关关系,其中,柳树（p〈0.05）、杨树（p〈0.05）和油松（p〈0.01）相关性显著;不同地点大气PM2.5质量浓度变化为西山森林公园（108.238μg/m~3）〉松山自然保护区（80.522μg/m~3）〉北京植物园（76.905μg/m~3）〉南...

Summary:以北京市6种常见树种为研究对象,测定不同园林绿化区PM2.5吸附量和质量浓度,探究绿化树种叶片在不同地区吸附PM2.5的变化规律及其与PM2.5质量浓度间关系。结果表明,不同树种叶片单位面积PM2.5吸附量差异显著,且在不同地点叶片吸附量变化规律基本表现为由“近郊—城区”逐渐下降,各树种叶片PM2.5的吸附量均与大气中PM2.5质量浓度呈正相关关系,其中,柳树（p〈0.05）、杨树（p〈0.05）和油松（p〈0.01）相关性显著;不同地点大气PM2.5质量浓度变化为西山森林公园（108.238μg/m~3）〉松山自然保护区（80.522μg/m~3）〉北京植物园（76.905μg/m~3）〉南海子公园（74.153μg/m~3）,表明树种叶片PM2.5吸附量随空气污染的加重而增加。

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 a
