广西负氧离子浓度的变化特征分析

Preliminary Study on the Variation Characteristics of Negative Oxygen Ion Concentration in Guangxi

利用2016年9月至2017年9月广西6个监测站大气负氧离子浓度连续观测数据资料,对广西负氧离子浓度变化特征进行了初步的统计分析。结果表明,广西负氧离子浓度具有明显的日夜差异,呈现出两头高、中间低的“V”字型,夜间至凌晨,负氧离子浓度普遍高于白天,最大值出现在早晨08:00左右,最小值出现在下午15:00左右,白天负氧离子浓度变化波动较大,夜晚变化较平缓。6个站中,大明山月平均大气负氧离子浓度值最高,达2453个/cm^3;四季中,夏季平均负氧离子浓度值最大,为2012个/cm^3。

Based on the continuous observation data of atmospheric negative oxygen ion concentration at six monitoring stations in Guangxi from September 2016 to September 2017,the variation characteristics of negative oxygen ion concentration in Guangxi were preliminarily studied.The results show that the concentration of negative oxygen ions in Guangxi has obvious diurnal variations.At night,the concentration of negative oxygen ions is higher than during the day.The maximum occurs at 8 am and the minimum occurs at 3 pm.The concentration of negative oxygen ions fluctuates greatly during the daytime and changes gently at night.Among the six stations,the monthly average concentration of negative oxygen ions in Daming Mountainis the highest,reaching 2453 per cubic centimeter;in the four seasons,the average concentration of negative oxygen ions reaches the maximum in summer at 2012 per cubic centimeter.
