Abstract: In order to get a better understanding of the correlation between respiratory diseases outpatients and atmospheric PM2:5, SO2 concentrations, multifractal detrended cross-correlation analysis (MF-DCCA) was used to study the sequence of respiratory diseases outpatients and PM2:5, SO2 concentrations in Yongding District. The  results show that the correlation between respiratory diseases outpatients and atmospheric PM2:5, SO2 concentrations has the characteristics of long-term persistence and multifractal. Then the dynamic sources of their correlation multifractal features are analyzed. Through random rearrangement and phase randomization procedure, the results show that the long-term persistence effect is the main driving force at different time scales. Further study found that the correlation between respiratory system diseases and atmospheric PM2:5, SO2 concentrations sequence in the four seasons has long-term multifractal characteristics, and the multiple fractal features in summer are stronger than those in other seasons.

Key words: PM2:5, SO2, multifractal, respiratory diseases, atmospheric pollutant
