摘　　要：在北京奥林匹克森林公园内的典型群落环境内外选定样点和对照点,并于2009年8月18—20日连续测定空气中的负离子浓度。结果表明:不同的群落结构条件下,乔灌草复合植物群落在影响负离子的产生效果方面要优于简单植物群落结构,尤其高于单层的群落结构,同时其与负离子浓度的相关性最大;不同的植被类型条件下,大面积的落叶阔叶林区域的负离子浓度要显著高于针阔叶混交林区域和针叶林区域。最后,综合比较空气负离子浓度与空气温湿度的关系,发现空气负离子浓度与空气湿度、空气温度呈正相关。In this study,sampling plots and control were chosen in the Beijing Olympic Forest Park（BOFP） and negative air ion （NAI） concentrations were measured continually in clear days of August 18-20,2009.The results indicated that the effect of plant community structure on NAI was significantly different.NAI concentration of the tree-shrub-grass communities was higher than that in the simple plant communities,especially higher than that in the single-layer ones.The correlation between multiple plant communities and NAI concentration was significant.Moreover,NAI concentration of the deciduous broadleaved forest regions was higher than those of the coniferous forest and mixed conifer and broad-leaved one.The results showed that there was positive correlations between NAI concentration and air relative humidity and air temperature.
