2004-2005年,通过对不同植被环境中空气负离子含量与空气质量的关系进行研究,结果表明,空气负离子含量的日变化在植被环境中变化趋势较一致,每个时段负离子平均含量约在800个.cm-3以上。从8：00开始空气中的负离子含量逐渐升高,到14：00时出现回落,但比8：00时要高,随后又有所增加,当到17：00左右开始逐渐下降。空气质量与负离子含量呈正相关关系。居民区负离子含量的变化与人为活动关系较密切,各时段的平均水平不超过500个.cm-3,但在10：00和16：00空气质量指数较高,空气质量较好。空气负离子含量与空气质量在旱季都比雨季要低,特别是在居民区雨季的空气质量指数平均水平是旱季的5倍之多。空气质量指数反映空气质量好坏,在森林植物环境中的空气质量指数要高于居民区8～160倍。

The relation between anion concentration and air quality in different types of vegetation environment had been investigated for 3 years.The results indicated that：daily variation of anion concentration was consistent in different types of vegetation environment,and average concentration of anion was above 800 in every cubic centimeter at each period time.Anion concentration increased gradually from 8：00 and decreased at 14：00,but the concentration was higher than that at 8：00.Anion concentration started to go down from 17：00.Air quality was positively correlated with anion concentration.In residential areas,the variation of anion concentration was closely related to human activities,and average concentration of anion was under 500 in every cubic centimeter at different period of time.But index of air quality was higher at 10：00 and 16：00,with better air quality.Air anion concentration and air quality in rainy season were better than those in dry season,especially in residential area where the index of air quality in rainy season was 4 times higher than that in dry season.Index of air quality reflects air quality.The index of air quality in forests was 8-160 times higher than that in residential areas,and the variations of anion and air quality in forests were relatively slight.
