[目的]研究峨眉山市4种不同林种的空气负离子水平变化规律.[方法]在研究区域内选取巨桉、杉木、杨树、苦竹进行负离子浓度的观测,将每日所测数据取平均值作为当日的空气负离子浓度值,绘制变化图,研究不同林种的负离子浓度的月、日变化特征.[结果]不同林种的空气负离子水平差异较大,阔叶树种(巨桉、杨树)高于针叶树种(杉木),苦竹的空气负离子水平最高.4种林种的空气负离子浓度在7月份出现高值,5和10月份的数值较低;8:00～10:00出现峰值,14:00～16:00出现谷值.不同林龄的杉木空气负离子水平为:幼龄林＜中龄林＜近成熟林＜成熟林.[结论]不同林种、不同林龄、空气湿度和太阳辐射与空气负离子浓度有一定的关系.

[Objective]The purpose was to study the variation law of aero-anion concentration in four different tree species in Emeishan City. [Method]The eucalyptus, Chinese fir, poplar and bitter bamboo were chose in researched area to observe their anion concewtration, the average values taken from the daily measured data were used as anion concn. value of that day to draw the change maps, and the variation characteristics of day and month of anion concn. in different tree species were studied. [Result]The aero-anion concn. had a great difference among each tree species, the broadleaved tree species (eucalyptus and poplar) were higher than that of coniferous species (Chinese fir), and the aero-anion concn. of bitter bamboo was the highest. The aero-anion concn. of 4 tree species showed peak values in July and lower values in May and Oct.. The peak value appeared at 8:00-10:00 a.m. and valley value occurred at 14:00-16:00 p.m. The aero-anion concn. of Chinese fir with different stand ages in order was as: young forest ＜ half-mature forest ＜ near-mature forest ＜ mature forest. [Conclusion]The different tree species, varied stand ages, air humidity and solar radiation had a certain relationship with aero-anion concn.
