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-valley'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 th...
