Aim To investigate the effect of temperature, humidity and the concentration of ambient air pollution on the hospitalization of AECOPD. Method Hospitalization record was obtained from Shenyang Medical Insurance Bureau, concluding patient's age, gender, income hospital time, outcome hospital; Generalized additive model was used to analyze the relationship between temperature, humidity, the concentration of ambient air pollution and the hospitalization of AECOPD. Result The effect of ozone on admission rate in male group was higher than that in female group. Ambient air pollution had a weak influence on age <= 50 group. It was found that the optimal lag day for daily relative 40 humidity to age <= 50 group, 50<= 60, 60<= 70 group and age> 70 group was on lag5, lag4, lag4 and lag5, respectively. Conclusion Air pollution, relative humidity and temperature can increase the risk of admission for acute exacerbation of COPD, and in this process there was a lag effect.
