The air anion concentration of typical plots in Ganfanpen forest park and urban in Jilin (CK) was determined, and the effects of stand structure on air anion concentration were analyzed and air quality in the forest park was evaluated. The results showed that the average concentration of air anion in the forest park was 958 Ions/cm~3, being obviously higher than that in urban. There were great differencees among air anion concentration in different stand structures. The clean degree of air in the forest park was grade A.%对吉林江源干饭盆森林公园典型样地和城区(对照)的空气负离子水平进行了测量,分析了林分结构对空气负离子水平的影响,并对森林公园内的空气质量进行了评价.结果表明,森林公园空气负离子平均水平为958 Ions/cm~3,明显高于城区,不同林分结构中空气负离子水平差别较大;森林公园内空气清洁程度为A级.
