摘　　要：在桂林国家森林公园选择不同的植被群落类型进行空气离子浓度监测,研究森林游憩区空气负离子浓度水平变化。结果表明:①不同植被类型样地的空气负离子浓度水平不同,阔叶林>针叶林>针阔混交林>灌丛≥草坪。②森林游憩区空气质量均较好,阔叶林覆盖下的空气清洁度最高,针叶林覆盖下的空气清洁度次之,灌丛和草坪区的空气清洁度相对较低。③空气负离子浓度水平呈现早上最高,中午降至最低,下午又逐渐升高的特点。To study the variation of aero-anion concentration in forest recreational areas, the concentrations of aero-ion were measured under different vegetation types in Guilin National Forest Park. The results were as follows：①The aero-anion concentration of different vegetation types decreased in the order as follows： broad-leaved forest〉coniferous forest〉coniferous and broad-leaved mixed forest〉shrub land≥turf.②The air quality in the forest recreational areas was good, which was best under broad-leaved forest, the coniferous forest took second place, the shrub land ＆ turf was correspondingly lowest.③The density level of aero-anion was the highest in the morning, the lowest at noon, and was gradually increased in the afternoon.
