Based on 12 months data of air negative ion in observation station from December of 2007 to November of 2008 in Jinggang Mountain, the concentration characteristics of air negative ion in this areas were analyzed, and the relationship between the concentration of air negative ion and meteorological conditions was discussed. The results showed that the minimum value of monthly average concentration was 2 610 per cubic centimeter, which occurred in January of 2008, while the maximum value was 7 126 per cubic centimeter, which occurred in November of 2008; the daily variation of air negative ion was not obvious, namely, the observation data of A. M. were not far different from that of P. M.. In addition, the air negative ion concentration rose markedly after shower, intermittent flurry and thunderstorm. The correlativity of the air negative ion concentration with relative humidity, wind speed, cloud cover, sunlight and precipitation were not obvious.%利用井冈山空气负离子观测站2007年12月～2008年11月12个月的资料,分析了该地空气负离子的浓度特征,探讨了空气负离子浓度与气象条件的关系.结果表明,月平均浓度最低值为2610个/cm3,出现在2008年1月;最高值为7 126个/cm3,出现在2008年11月;负离子浓度日变化不明显,上午、下午的观测值差别不大.在阵雨、间歇性小雨和雷暴天气过后,负离子浓度明显升高.负离子浓度与相对湿度、风速、云量、日照、降水量的相关性均不明显.
