摘　　要：对比分析广东南雄小流坑-青嶂山自然保护区与城区、乡镇的空气负离子变化特征,探究森林植被对空气负离子的调控作用,为森林旅游资源开发和生态环境建设提供理论支撑。使用空气负离子仪对2019年保护区内外的空气负离子浓度进行实地对比观测和分析。研究结果表明:(1)空气负离子浓度空间分异明显,保护区内空气负离子年平均值为1194 ion·cm^(-3),分别是乡镇和城区的1.5倍和2.8倍;(2)保护区内空气负离子浓度的季节性变化显著,夏季最高,冬季最低,但城区空气负离子的季节性变化不显著;(3)一天之内,空气负离子浓度上午或者傍晚最高,中午最低,下午居中。森林对空气负离子具有明显的调控作用,森林质量越好,空气负离子浓度越高。Spatiotemporal variations of negative air ion concentration were analyzed and compared with the urban and suburban areas to explore the regulatory effect of forest vegetation on negative air ion in Xiaoliukeng-Qingzhangshan Nature Reserve,Nanxiong city,Guangdong province.this study will provide scientific data for the exploration of forest tourism resources and the protections of ecological environment.The air anion meter is used to conduct field comparative observation and Analysis on the air anion concentration inside and outside the reserve in 2019.The results indicate that:(1)Negative air ions concentration is closely related with land type.The average value of negative air ions concentration of four forest sites was 1194 ion·cm^(-3),which is 1.5 and 2.8 times of the suburban and urban site,respectively.(2)Negative air ions concentrations of four forest sites varied seasonally.The peak of the concentrations occurred in summer,and the lowest was in winter.However,seasonal variations in urban site were not significant.(3)During one day,the concentrations of negative air ions were highest in the morning or evening,and lowest at noon.Xiaolukeng-qingzhangshan nature reserve is rich in negative air ions,which is higher than those in the urban and suburban area.Therefore,forest is conductive to negative air ion production.The higher forest quality,the more negative air ions.
