First, the main meteorological factors imfluencing air negative oxygen ion concentration and the relationship between impact factors and air negative oxygenion concentration was analysed using in-site negative oxygenions concentration observations from 14 automatic measuring system and synchronous meteorological elements observations, and using correlation analysis, regression analysis method. Then oxygen ions concentration forecasting model is established. The results show that: There was no significant correlation between air negative oxygenion concentration changes and seasonal changes of meteorological factors in Yuxi, the main meteorological factors influencing diurnal variations of air negative oxygenion Yuxi are relative humidity and air temperature. When the air temperature is less than 20.4℃, the negative oxygenion concentration diurnal variation with air temperature was negatively correlated. However, when the air humidity is greater than 45.6%, negative oxygenion concentration with air humidity was positively correlated. Based on the research results, the negative oxygenion concentration prediction model was established. The forecast effect is better and through statistics test and it could be useful for the operational service.
