摘　　要：选择浙江林学院东湖校区作为监测点,通过测定空气正、负离子浓度,空气温、湿度,风速,光量子等项目对空气负离子浓度变化特征进行研究.结果表明:白天空气负离子浓度有一个高峰期,出现在8:00—9:00;8月空气负离子浓度最高;空气负离子浓度随相对湿度的升高而增大,随温度、风速和光量子的增大而降低.Choosing the Donghu campus of Zhejiang Forestry University as a monitoring spot, the concentration of both positive and negative air ions, air temperature and relative humidity, wind speed and photons are measured to investigate the variation of negative air ions around the place. The results show that at daytime a peak of negative air ions concentration would appear during 8 ： 00-9 ：00 ; the concentration of negative air ions reaches the maximum in August; and the concentration of negative air ions would increase with the rise of relative humidity, but go down with the increase of air temperature, wind speed and photons.
