Abstract: To study the effects of aeroanion concentration surrounding 8 landscape trees,It shows that the aeroanion concentration are significant difference.For these 8 trees,the order of their aeroanion concentration surrounding is Cinnamomum micranthum,Podocarpus macrophyllus,Parakmeria lotungensis,Manglietia fordiana,Manglietia chingii,Michelia foveolata,Michelia chapensis,Liriodendron chinense.The concentrations of aeroanion in forest are significantly different by negative relation to the environment temperature,while it is different by positive relation to the atmosphere humidity.As for one tree species,the aeroanion concentration surrounding shows regular variety.
