摘 要: | 主要研究空气污染中的PM2.5扩散问题.首先利用相关分析法讨论了PM2.5与SO_2,NO_2,CO,PM10,O_3的相关性,建立线性回归方程;然后建立一维的反应扩散方程,预测PM2.5浓度变化,并定量与定性分析西安市空气污染状况;再建立高斯烟羽模型,对持续高浓度PM2.5扩散情形进行拟合,并对污染物扩散范围进行预测,得到重度污染以及可能安全区域;最后通过建立最优化模型,得到较有经济效益的空气治理方案.

Abstract: | In this passage,we mainly study PM2.5 air pollution diffusion problem.Firstly,using correlation analysis to discuss the relation between PM2.5 and SO_2,NO_2,CO,PM10,O_3.And set up linear regression equation.Secondly,establish one-dimension reaction diffusion equation and predict the exchange of PM2.5 density,so that we can analysis the current situation of the air pollution in Xi'an.Then set up gaussian plume model and simulate continuous high density of PM2.5 diffusion,so we can predict its diffusion range,intense pollution and possible safety areas.Finally,through the establishment of optimization model,get more economic and effective method to control the air. |
