利用2009年1～12月的负离子连续自动监测数据，对东莞市板岭观测站负离子浓度的日变化、年变化等特征进行分析，同时针对负离子浓度与相对湿度等气象因子的相关性进行分析。结果表明：负离子浓度（迁移率为1时）在3级以上的频率为16％；呈现夏季浓度较高、秋季浓度达到最低的季节变化特征；在一天中呈明显的双峰型变化规律，极大值出现在03：00～07：00、21：00～02：00之间，而极小值出现在12：00～17：00之间；与天气现象关系是，雷阵雨〉晴〉阴〉轻雾灰霾〉灰霾〉雨；与温度、湿度、日照呈负相关，其中温度在7．2～32．0℃时负离子随温度上升而下降；当湿度在28％～93％RH时，负离子浓度随相对湿度上升而上升。

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.
