摘要
Abstract
In this paper,a 30 MHz to 6 GHz EMF vehicle survey was carried out in two administrative districts of Beijing.More than 1.33 million data records of electric field intensity were obtained,which were fell into 22 subdistricts and towns in each of the two administrative districts based on geographical location information.The average RF total value was calculated.The average ranges are(0.43-1.67)V/m,(0.56-1.51)V/m respectively;The correlation coefficients with the population density and base station density of each subdistricts and towns are all higher than 0.8,indicating a strong positive correlation.On the other hand,a 24 hour 30 MHz to 6 GHz vehicle survey was carried out in a business district of Beijing,and the total RF value and base station RF value of 24 groups with a total of more than 145,000 points were obtained.The measured values ranged from(0.70-1.46)V/m and(0.67-1.31)V/m,respectively;The hourly population density was calculated by analyzing the heat map of Baidu population flow,which ranged from(6.58-46.54)human/hm2.It is found that the correlation coefficients between hourly population density and hourly RF and base station RF values are as high as 0.901.Obviously,the regional electromagnetic level is strongly correlated with the spatial distribution of population density and the 24 hour fluctuation of regional electromagnetic level is strongly correlated with the variation trend of population flow concentration density.关键词
