Characteristic Analysis of Air Negative Oxygen Ions Concentration in Huoshan
Based on the data of three negative oxygen ion monitoring stations in Baimajian,Xianrenhu,and You'erjie in Huoshan County,combining ground meteorological observation data,the distribution characteristics of negative oxygen ion concentration and the influence of meteorological factors on negative oxygen ion concentra-tion in Huoshan area are analyzed.The results show that negative oxygen ions in Huoshan is very rich and is very good for human health.The annual average concentration of negative oxygen ions is above 2500ind/cm3,while it is higher in mountainous than that in suburban and plain.The average concentration of negative oxygen ions is the lowest in winter,and varies from place to place in other seasons.The concentration of negative oxygen ions is sig-nificantly positively correlated with temperature and precipitation.On a sunny day without precipitation,the hour-ly change trend of negative oxygen ions concentration is relatively consistent with temperature.During precipitati-on,it is greatly affected by precipitation.Compared with weak precipitation in winter,strong precipitation in sum-mer has a more significant effect on enhancing the concentration of negative oxygen ions.
