摘要：

为阐释不同污染程度下城市绿化植物吸滞PM_(2.5)机理、解析污染物来源,应用气溶胶再发生器定量测定长沙市常见的2种园林绿化树种(桂花和香樟)植物叶片PM_(2.5)吸附量,同时应用原子力显微镜( AFM)观察了不同污染区(交通区、文教区、清洁区)植被的叶表面微形态特征,使用离子色谱仪测定样品中水溶性离子含量.结果表明:污染程度与植物叶表面 PM_(2.5)吸附量呈正相关,不同植物单位叶面积PM_(2.5)吸附量全年均值表现为交通区( 0.56±0.04 μg·cm~(-2) ) >文教区( 0.48±0.06 μg·cm~(-2) ) >清洁区( 0.33±0.02 μg·cm~(-2) ) ,植物单位叶面积 PM_(2.5)吸附量季节变化为冬季( 0.70±0.10 μg·cm~(...

摘要(英文)：

To understand the PM2.5 adsorption mechanisms of plants under different pollution levels and analyze pollutant sources, the PM2.5 adsorption amount of the leaves of two garden plant species (Cinnamomum camphora and Osmanthus fragrans) in different polluted level area (traffic area, culture and education area, cleaning area) of Changsha was measured using an aerosol generator. AFM scanning was used to obtain leaf surface micromorphological characteristics. Ion chromatography was used to measure the water-soluble ion content. Results showed that amount of PM2.5 adsorbed by leaves was positively ...
