摘　　要：采用空气负离子测量仪,在柑橘采摘游时段内,对衢州大橘海森林公园内柑橘纯林绿地的空气负离子浓度进行了监测,并评价了柑橘纯林的空气负离子浓度及其与环境因子的关系。研究结果表明,柑橘纯林的空气负离子浓度总体水平处于798～1 641个.cm-3,均超过700个.cm-3,有益于人体健康,具有保健功能。一天中空气负离子浓度随时间的变化呈现出明显的规律性:波谷和波峰交替出现的单峰曲线,波谷出现在12:00,波峰出现在14:00。空气质量评价系数CI均值为0.892,空气质量等级总体达到B级水平,即清洁程度。CI在08:00最高,12:00最低。柑橘纯林空气负离子浓度与气温呈负相关,与湿度呈正相关。An experiment was carried out to study the aero-anion levels in citrus plantations in Quzhou Juhai Forest Park.The relationship between aero-anion concentration and environmental factors was analyzed to provide scientific basis for the further development of the local tourism.The results showed that the aero-anion concentrations in citrus plantation were between 798-1 641 cm^-3,higher than 700 cm^-3,which was considered as a beneficial threshold for human healthy.A single peak curve was observed for the changes of aero-anion levels in daytime： lowest at 12：00,highest at 14：00.The average CI was 0.892,reached the level of B.The highest CI was at 08：00 am while 12：00 am was the lowest.The aero-anion concentration was negatively correlated with temperature and positively correlated with humidity.
