摘要
Trees can capture PM on account of their foliage's structure, thus, improving air quality. We determined leaf PM-retaining capability (PM2.5, PM>2.5, PM) of evergreen shrub ( Euonymus japonicas) and decicuous trees (Sophora japonica, Fraxinus chinensis, Ginkgo biloba, Populus tomentosa) in different functional areas. The leaf micromorphological structure was observed using a field emission environmental scanning electron microscopy. We found that E. japonicas should be planted in traffic and industrial areas, while S. japonica, G. biloba, F. chinensis should be chosen as complementary in clean areas. S. japonica, G. biloba were adapted well to polluted environment, but, F. chinensis was not.
