东莞市植物园空气负离子浓度变化特征
Variation features of negative ion concentration in Dongguan botanic garden
摘要
Abstract
Based on the Dec. 2009, the da observation station ily of negative ion data monitored continuously and automatically from Jan. 2009 to and annual variation of negative ion concentration is analyzed in Banling Dongguan city. Meanwhile, the correlation between negative ion concentration and meteorological factors such as relative humidity are also discussed. The results show that the probability of negative ion concentration （mobility 1） above 3 level is 16~; concentration is much higher in summer and lowest in autumn; it appears obvious double peak variations in a day while the maximum value appears at 03.00-7.00 and 21.00-02：00, and the minimum value is at 12.00-17. 00; the relationship between negative ion concentration and weather phenomena is thundershower clear day〉overcast〉 light fog 〉 haze 〉rain; it is negatively related with temperature, humidity and sunshine, for example negative ion concentration decreasing with temperature rised at 7.2-32.0℃ and the situation is the same when humidity is at 28%-93%RH.关键词
