摘　　要：为了掌握厦门市电磁环境状况,于2014—2015年对厦门市进行网格分区季度监测,由监测数据发现厦门市区的电磁辐射强度较低,其整体电磁环境监测值符合《电磁环境控制限值》(GB 8702—2014)标准的要求。不同区域低频磁感应强度呈现工业区>商业区>文教居住区>旅游风景区的特点,其中商业区、文教居住区比总体平均水平(0.181μT)略低;射频电磁辐射呈现工业区>商业区>旅游风景区>文教居住区的特点,商业区、旅游风景区的平均辐射强度比较接近,接近平均水平(0.73 V/m);运用主成分法分析电场和磁场分布的综合特征,分布表现为4个主成分;还发现了4代不同代际移动通信信号的分布规律,一代、二代手机代表通讯频段信号强度更高,强信号覆盖的范围也更大;三代手机代表通讯频段信号在中心城区、商业区和个别旅游风景区较强;四代手机代表通讯频段信号在中心城区和商业区较强。In order to grasp the electromagnetic environment of Xiamen,the intensity of EMF in the city was monitored quarterly in 2014-2015.It was found from the monitoring data that the intensity of electromagnetic radiation was low in Xiamen and the value met the electromagnetic environment control limit value （GB 8702-2014） standard requirements.The intensities of low frequency electromagnetic fields in different regions were as follows：industrial area 〉 commercial area 〉 cultural,educational and residential area 〉 tourism scenic area.In commercial district,cultural and educational residential area,the intensities were slightly lower than the average level of 0.181 μT;as for RF electromagnetic radiation,industrial zone 〉 commercial area 〉tourism scenic area 〉 cultural,educational and residential area.The average radiation intensity in commercial area and tourism scenic area was close to the average level of 0.73 V/m.The principal component method was used to analyze the comprehensive characteristics of the electric and magnetic fields,and the distributions were represented by four principal components.Distribution characteristics of four different generations of mobile phone communication were found.The signal intensities of the first and second generation mobile communication bands were higher and the range of strong signal coverage was larger.The third generation band signal was stronger in the central city,business district and individual tourism scenic area.The fourth generation band signal was stronger in the central city and commercial district.
