Abstract:In order to evaluate the impact of environment by electromagnetic radiation generated from mobile communication base station in Xinjiang Hami, according to the relevant specifications and requirements, this paper selected the typical mobile base station in Hami to monitor. The monitoring data were collected and the monitoring results show that: the maximum value of the electric magnetic radiation intensity monitoring was 0.446μW/cm2, which was far lower than the goal of environmental management a value of 8μW/cm2. They were in accordance with the relevant requirements. The overall level of electromagnetic radiation level of mobile base station in Xinjiang Hami is low.

哈密地区位于新疆东部,是新疆通向中国内地的要道,自古就是丝绸之路的咽喉,近些年来随着当地国民经济的快速发展,建设了一大批移动通信基站,而通信基站的大量建设势必会造成电磁辐射环境污染,影响人们的正常生活。为了研究新疆哈密地区移动通信基站的电磁辐射水平,评价其危害程度和环境影响程度,本文在以往研究成果[1-11]的基础上,对新疆哈密地区典型移动基站的电磁辐射水平进行监测,并对监测数据进行整理、分析、总结和归纳,最终确定其对环境的影响程度。
1 移动通信基站工作原理
移动通信基站是连接通信网络与移动用户的纽带,负责将网络侧的信息以无线电磁波的形式与移动终端进行交互,移动通信基站天线是将传输线中的电磁能转化成自由空间的电磁波,或将空间电磁波转化成传输线中的电磁能的专用设备。在无线通信系统中,天线是收发信机与外界传播介质之间的接口。……
