摘　　要：目的了解鹞落坪自然保护区自然环境中空气离子状况及CO2含量,为制定负离子卫生标准以及负离子的应用提供依据。方法采用仪器法现场测定正、负离子浓度与CO2含量,并用单极系数和“安培”空气质量评价指数进行卫生学评价。结果鹞落坪自然保护区自然环境空气中空气负离子总平均浓度为4 012个/cm3,正离子总平均浓度1 760个/cm3,CO2含量总平均值0.037%。空气离子卫生学评价结果,单极系数在人体舒适感范围内,空气质量评价指数达到A级以上,为最清洁空气。结论鹞落坪国家级自然保护区空气负离子含量高,是一笔巨大的天然财富,有很高的保健、疗养利用价值。Objective To explore the air ions status and CO2 content in Yaoluoping Nature Reserve in order to provide evidences for establishing the standard of negative air ion and its application. Methods Concentrations of anode , negative air ions and CO2 content were measured by special instruments and assessed with single grade coefficient and ＂ampere＂ air quality evaluation index. Results The average concentrations of anode, negative air ions in Yaoluoping Nature Reserve werel 760/cm^3 and 4012/cm^3 , the average value of CO2 was 0.037% . Air ions hygienic evaluation was in the range of comfort, and the air quality evaluation index was up to A grade（the best clean air）. Conclusion The content of negative air ion in Yaoluoping Nature Reserve is tremendous and valuable resource for htunan health care.
