| 摘 要： | 采用美国进口的空气离子测定仪,对福州市空气负离子浓度的空间变化情况进行了初步的实测与研究,并以单极系数和空气离子评价指数为标准对其空气质量进行评价。结果表明:从福州市中心向郊区空气负离子浓度逐渐增大,单极系数逐渐减小;有林地区空气负离子浓度明显高于无林地区,一般情况下阔叶林地空气负离子浓度高于针叶林地。

| Abstract: | With the air ions counter made in USA,the spatial changes of negative air concentrations were detected in Fuzhou and around in different time,and air quality was assessed by using ion polarity ratio and air ion assessment index(CI).The results showed that negative air ion concentrations increased gradually and ion polarity ratio decreased gradually from city center to suburb.The negative air ion concentrations in forested areas were obviously higher than those in non-forested areas.The negative air ion concentrations in broad-leaved forested area were usually higher than those in coniferous forested area. |
