摘 要: 本文以南京为研究对象,考虑可能影响监测装置布设的因素,包括PM2.5预计浓度含量、地区经济发展水平、人口密度。综合风的因素运用大气环境模式里的扩散参数及虚点源的模型得出浓度函数,对七个主城区进行网格处理,对每一个格点计算装置布设的综合指数,确定监测点的位置。 This paper takes Nanjing as research object and con- siders factors that may affect the monitoring device layout, in- cluding forecast concentration of PM2.5, regional economic de- velopment level, population density. Taking wind into accord and using the atmospheric environment in the mode of diffusion pa- rameters and virtual point source, get concentration function. Meshing processing for seven main urban quarter and calculating the comprehensive index in every point and determining the po- sition of the monitoring points.
