空气负氧离子浓度水平不仅反映了空气质量，还直接影响人们的舒适程度和健康状况。研究武夷学院空气负氧离子浓度含量发现，其受人类活动力度、海拔高度、空气流通状况、动态水体和植被分布等综合因素影响，并具有明显的气象变化和日变化特征。负氧离子浓度含量排序为：暴雨天＞小雨天＞雨后阴天＞晴天；一日中上午＞傍晚＞中午。测量结果表明该校园整体空气质量等级达到四级或者三级，空气清新，有利于师生健康。

Level of negative oxygen ions concentration reflects not only the air quality, but also directly affect the comfort and health.This paper studied distribution and evaluation of negative oxygen ions concentration in campus of Wuyi university.The re-sults showed that negative oxygen ions concentration was affected by human activity, altitude, the air flow, dynamic water and vege-tation distribution and other comprehensive factors in the different functional areas of the campus.Meanwhile, negative oxygen ions changes according to weather and diurnal variations.Ranges of negative oxygen ion concentration are as follows:heavy rain days>rain days>rain cloudy>clear;diurnal variation order:AM>evening>noon.In summary, the measurement results showed that the air quality levels achieved stability three or four, air was fresh and conducive to human health.
