摘　　要：大气污染是人类面临的环境危机之一,依据植物对大气污染的修复能力来选择城市绿化植物是减轻大气污染的重要途径和手段。植物叶片内大气污染物含量既可反映大气污染的水平,又可反映植物对大气污染的修复吸滞能力。研究结果表明:城市绿化树种对大气污染具有很强的吸收修复能力,并依树种的不同具有明显差异。修复大气SO2污染能力强的树种有:加杨、旱柳、花曲柳。Air pollution is one of environmental crisis in the face of human beings. To seclect urban planting tree species according to ability of plant remediation for air pollution is a very important approach and means to reduce air pollution. Content of air pollutants of leaves of planting trees can show degree of air pollution, ability of remediation, and absorbability of planting trees for air pollutants. The studying results shows planting trees bave a high ability of restoration and absorbability, which varies with plant species. The plants that have high restoration ability for sulfur include Populus×Canadensis, Salix matsudana, Fraxinus rhynchophylla.
