摘 要:空气负离子浓度的高低反映了空气质量的好坏.文章选择了长沙市代表性的4个功能区进行了空气负离子浓度监测,并进行了空气质量的评价.结果表明:(1)空气负离子浓度日变化幅度较大,空气负离子水平和空气质量出现峰谷交替的现象;(2)不同植被的城市绿地空气负离子水平差异较为明显,以乔木为主的岳麓山空气负离子浓度最高,空气质量最佳;(3)不同功能区的空气负离子水平差异较为明显,城市绿地的空气负离子浓度最高,空气质量最好.Negative air ion concentration reflects environmental quality. In this paper, air anion concentration were measured in four functional areas of Changsha and their air quality evaluated. The results showed that: (1) the change amplitude of air negative ion concentration level was larger and the air anion concentration level and the air quality showed the phenomenon of the peak-to-vaUey's alternation; (2) air anion concentration level were markedly different in different structures of urban green space, the air anion concentration level of Yuelu mountain wooded with trees was the highest and the air quality was the best; (3) air anion concentration levels of different functional areas of urban were markedly different. During different function areas, air anion concentration was the highest and the air quality, the best at urban green space.
