摘要:
选取北京市环境电磁辐射自动监测站点2年多的数据,利用SPSS统计软件,对各站点数据进行了主要电磁辐射源、长期数据趋势、各站点时间代表性分析;并结合网格法监测数据,对自动站点空间代表性进行分析。结果表明,5个环境电磁辐射自动站周围主要电磁辐射源均为移动通信基站;其总体电磁辐射水平为0.69~0.97V/m,低于北京市1 V/m的电磁辐射环境本底水平,且单站点连续12个月的监测数据可以描述该点位电磁辐射平均水平和变化趋势;经分析,连续5年全市网格法电磁辐射射频电场的监测数据总体具有较好的一致性,但单站点的电磁辐射水平不能代表所在行政区的电磁辐射总体水平。提出了电磁辐射自动监测网络建设建议。

Abstract:
Retrieve, filter and reprocess over 2 year data from Beijing five environmental continuous monitoring stations of electromagnetic field (EMF), to conduct 4 analyzing tasks with statistical software—SPSS, which includes determining main EMF sources in the vicinity of the monitoring station, interpreting long term trends of EMF,analyzing temporal representative on the basis of one year measurements, and combining grid data to analyze spacial representative. It reveals that the dominant electromagnetic radiation sources are telecommunication base stations in the vicinity of 5 environmental continuous monitoring stations; and the EMF levels range from 0.69 to 0.97 V/m, which are lower than the background level of 1V/m of Beijing and 12 month continious monitoring data of one station could describe the average EMF level and variation trend; Moreover, the results show that consecutive 5-year EMF levels of radio frequency in Beijing area with grid method have better consistency, but long term average level of one station could not represent the level of the district where the station located.Based on the analyzing results, suggestions on selection, minimum monitoring periods and so on have been discussed and put forward.
