摘要
对8种园林树种周围空气中的负离子水平进行研究,结果表明:不同树种周围空气负离子水平差异显著,参试的8种园林树种周围空气中负离子水平排序依次为:沉水樟、罗汉松、乐东拟单性木兰、木莲、南方木莲、金叶含笑、乐昌含笑、中国鹅掌楸;森林环境中空气负离子浓度与环境温度呈极显著负相关关系,与空气相对湿度呈显著正相关关系;同一树种周围环境中空气负离子浓度呈现规律性变化。
To study the effects of aeroanion concentration surrounding 8 landscape trees,It shows that the aeroanion concentration are significant difference.For these 8 trees,the order of their aeroanion concentration surrounding is Cinnamomum micranthum,Podocarpus macrophyllus,Parakmeria lotungensis,Manglietia fordiana,Manglietia chingii,Michelia foveolata,Michelia chapensis,Liriodendron chinense.The concentrations of aeroanion 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 aeroanion concentration surrounding shows regular variety.
