黑龙江省丰林县空气负氧离子变化特征

利用黑龙江省丰林县气象局空气负氧离子历史数据,对丰林县空气负氧离子浓度变化特征开展研究。数据表明,丰林县空气清新,负氧离子丰富。每日05:00—12:00,15:00—18:00空气负氧离子浓度逐步提升,最高浓度平均值为3489个/cm^(3)。每日24:00至翌日05:00空气负氧离子浓度则相对较低,最低浓度平均值为1269个/cm^(3)。空气负氧离子浓度最高值出现在10月,最低值出现在1月;空气负氧离子浓度季节变化特征较为显著,冬季—春季—夏季—秋季负氧离子浓度逐渐升高,秋季达到最高,冬季最低。空气负氧离子浓度与空气湿度表现为正相关性,空气负氧离子浓度与温度表现为负相关性。

Based on the historical data of negative oxygen ion concentration in Fenglin county,Heilongjiang Province,the characteristics of the change of negative oxygen ion concentration in Fenglin county were studied.The data shows that Fenglin county has fresh air,rich in negative oxygen ions.The concentration of negative oxygen ions in the air gradually increases from 05:00 to 12:00 and from 15:00 to 18:00 every day,and the average value of the highest concentration is 3489/cm^(3).The concentration of negative oxygen ions in the air is relatively low from 24:00 to 05:00 of the next day,and the average of the lowest concentration is 1269/cm^(3).The highest value of air negative oxygen ion concentration appeared in October,and the lowest value appeared in January.The seasonal variation of air negative oxygen ion concentration is significant.The concentration of negative oxygen ion increases gradually from winter to spring to summer to autumn,reaching the highest in autumn and the lowest in winter.Air negative oxygen ion concentration is positively correlated with air humidity,and it is negatively correlated with temperature.
