摘　　要：利用场部和青龙桥2个监测站2020年1—12月的大气负氧离子自动监测数据,分析了八达岭附近逐时、逐月负氧离子浓度变化和气象要素与大气负氧离子的相关性。结果表明:八达岭林场管理处整体的负氧离子浓度较高,绝大多数负氧离子浓度在1000个/cm^(3)以上;负氧离子浓度具有显著的逐时、逐月变化,以“时”为单位,上午10:00和11:00左右的负氧离子浓度较高,以“月”为单位,8月和9月负氧离子浓度较高;大气负离子受到气象要素的影响十分复杂,同一月份同一气象要素2个监测站呈现的相关性不同,同一气象要素同一个监测站不同月份相关性也不同。Based on the automatic monitoring data of atmospheric negative oxygen ions from January to December 2020 at the two monitoring stations of the station and Qinglongqiao,the hourly and monthly changes of negative oxygen ion concentration near Badaling and the correlation between meteorological elements and atmospheric negative oxygen ions were analyzed.The results showed that the overall negative oxygen ion concentration of Badaling Forest Farm Management Office was high,and the concentration of most negative oxygen ions was 1000 particles/cm^(3) above;The negative oxygen ion concentration has significant hourly and monthly changes.In the unit of“hour”,the negative oxygen ion concentration is higher around 10:00 and 11:00 a.m.,and in the unit of“month”,the negative oxygen ion concentration is higher in August and September;The influence of atmospheric negative ions by meteorological elements is very complex,The correlation between the two monitoring stations of the same meteorological element in the same month is different,and the correlation between the same meteorological element and the same monitoring station in different months is also different.
