摘  要：
2010年在黔南州选择具有代表性的不同森林类型进行实地检测空气负离子、氧气及萜烯类物质含量,采取统计分析、对比分析的方法对森林空气中各项保健因子进行分析。结果表明,黔南州森林环境中空气负离子的平均浓度达2 200个/cm3,明显高于非林区;平均氧浓度超出正常空气氧浓度的0.26%,其中针阔混交林中氧气浓度要高于其他类型的林分;萜烯类物质近20种,主要包括α-蒎烯、β-蒎烯和蒈烯等单萜烯以及环戊二烯、异戊三烯、长叶烯等多萜烯,平均浓度为0.012 8μg/m3;针叶林释放的萜烯类物质浓度高于其他类型林分,其中针叶林释放的多为单萜烯物质,阔叶林释放的多为多萜烯物质。大部分森林环境中空气质量为A级,即达到最清洁的水平,其中森林公园明显高于其他森林环境。因此,黔南州整体空气质量极佳,适于开展休养保健游。

摘  要：
Typical different forest types in Qiannan prefecture of Guizhou province were selected to investigate the contents of aero-anion,oxygen and terpenoids chemicals in 2010 with the aim of study the hygiene factors in forest environment. The results showed that the average concentrations of aero-anion in Qiannan forest environment up to2 200 ind·cm- 3,significantly higher than non-forest area. The average oxygen concentration was 0. 26 % higher than the normal air,the oxygen concentration of coniferous and broadleaf mixed forest was higher than other forest types. There are nearly 20 kinds of terpenoids chemicals mainly including monoterpenes of alpha pinene,beta pinene and careen,and polyterpene of cyclopentadiene,isoamyl triene and longifolene terpene,with the average concentration of 0. 0128 μg·m- 3. Monoterpenes were mainly released by the coniferous forest and polyterpene were mainly released by the broadleaf forest. The air quality in most of the forest environment is A grade,reached the level of the cleanest,and the air quality in forest park is significantly higher than other forest environment. It is therefore concluded that the overall air quality in Qiannan prefecture is admirable and suitable for health tourism.
