城市园林绿化树种叶片滞尘与SO2吸收能力分析——以长春市为例

为创建功能景观以改善空气质量并为城市绿化植物科学配置提供依据,测定、分析了长春市40种主要园林绿化树种的滞尘效果及吸收空气中SO_2的能力.结果表明:不同树种的滞尘及吸收SO_2能力存在差异.其中,梓树、山楂、山梨、银杏、金老梅、榆叶梅、毛樱桃滞尘能力较强,可作为长春市良好的滞尘树种;灌木吸收SO_2能力强于乔木,垂柳、五角枫、黄波萝、李、银杏、暴马丁香、鸡树条荚蒾等净化空气中SO_2能力较强,可作为长春市的空气净化树种.

Leaves Dust-retention and SO2 Uptake Capacity of Main Urban Landscape Tree Species——A Case Study of Changchun City

To construct functional landscapes for improving air quality and provide basis for the scientific configuration of urban greening plants,the dust-retention effect and the ability of absorbing SO2 in 40 kinds of main landscaping trees in Changchun were analyzed and measured. Result shows that the dust absorption capacity and SO2 uptake capacity of different tree species are different;Catalpa ovata G. Don, Crataegus pinnatifida Bunge,Pyrus vssuriensis Maxim, Ginkgo biloba L, Dasiphora fruticosa ( L. ) Rydb, Prunus triloba Lindl, Cerasus tomentosa( Thunb. ) Wall have as well dust-retention species in Changchun city;Shrubs can absorb SO2 stronger than arbors,Salix babylonica L,Acer mono Maxim,Phellodendron amurense Rupr,Prunus salicina Lindl,Ginkgo biloba L,Syringa reticulata,Viburnum sargentii Koehne have stronger SO2 uptake capability,they can be used as air purification species in Changchun City.
