摘　　要：采用美国进口的空气离子测量仪,在桂东县的主要景点测定空气正、负离子浓度,并用相关方法进行评价,同时与其他地区进行对比,结果表明本区空气负离子含量整体水平高,空气质量达到最清洁程度.根据测定结果,分析了不同生境空气负离子分布状况,发现山地空气负离子的垂直变化较为明显,河谷、山体的中下部和山顶空气负离子含量高,乡村和城郊空气负离子含量较高,市中心广场最低.空气负离子可作为该县旅游开发的重要资源,并对如何利用空气负离子进行开发,发展生态旅游提出了相关建议.With the air ions counter, the concentration of negative air ions was measured in scenic of Guidong county. By compared them with other areas, the result shows： the level of negative air ions concentration in this area is higher, and that the air quality in the area is very clean. Based on these concentration results, the distribution of the negative air ions and air quality change in different environment are analyzed, it is found that the vertical change of the negative air ions is obvious, it is the highest in the valley, lower-central of the mountain and the peak; it is higher in the village and suburban than in the centre of the city square. The negative air ions should be important resources in the processes of developing tourism in Guidong county, some suggestions are given on how to use it to develop ecology tourism.
