摘要: 通过对福建三明城市绿道空气负离子测定,研究绿道空气负离子变化规律。结果表明,不同绿化结构负离子浓度为乔灌草>灌草>草坪>对照;不同水体景观负离子浓度为瀑布区>流水区>静水区;瀑布区空气负离子清晨浓度较高,午后浓度较低,瀑布核心区空气负离子浓度均在10 000 个·cm-3以上。

关键词: 绿道, 空气负离子, 空气清洁度

Abstract: Based on the measurement of air anion, the changes of air anion of the greenway in Sanming City were studied. The results showed that the concentration of air anion in different planting structure was tree shrub lawn>shrub lawn>lawn>contrast. The concentration of air anion in different waterscape was waterfall>rivulet>backwater. The concentration of air anion in core area of waterfall was high in the morning and low in the afternoon. The concentration of air anion in core area of waterfall was more than 10 000 ions·cm-3.

Key words: the greenway, aeroanion, air cleanliness
