Temporal dynamics and relationship between negative air ions and environmental factors in subtropical forests, China.

ABSTRACT: Negative air ions (NAIs) in forest air contribute to air purification, improve respiratory system function, enhance immunity, reduce fatigue, and alleviate stress and anxiety. However, NAIs are easily influenced by meteorological factors, air quality factors, and radiation factors, and the mechanisms of these influences remain unclear. To investigate the dynamic changes of NAIs and their driving factors, this study focuses on the long-term monitoring of NAIs in the Yunzhong Mountain forest of the South Asian subtropical region in China. Using linear mixed models, structural equation models, and other ecological niche models, the study explores the characteristics of the dynamic changes in NAIs and their responses to meteorological factors, air quality factors, and radiation factors in the
