Different Time Scale Distribution of Negative Air Ions Concentrations in Mount Wuyi National Park

Negative air ions (NAIs) concentrations in Mount Wuyi National Park exhibit distinct seasonal patterns primarily influenced by relative humidity, with water emerging as a critical factor across time scales. Correlation and regression analyses revealed strong dependencies between NAI levels and meteorological conditions year-round, while the ARIMA (0,1, 1) model proved most accurate for forecasting future trends, minimizing errors compared to other models. This study advances our understanding of NAI distribution dynamics, offering insights into air quality assessment in protected natural environments like UNESCO World Heritage Sites.
