基于扩散模型的京津冀地区空气污染研究

Air pollution in Beijing-Tianjin-Hebei region based on diffusion model

综合分析京津冀地区的空气污染指标数据,首先建立正交因子模型,利用SPSS软件找出京津冀地区主要的污染源及其污染参数,其次结合具体案例分别建立单污染源和多污染源的扩散模型,使用Matlab软件编程,描述了其对周围空气污染的动态影响规律及空气污染浓度的时空梯级分布.

Aiming at the problem of air pollution,comprehensive analysis is carried out for air pollution index data of Beijing,Tianjin and Hebei province. firstly the orthogonal factor model is set up,using SPSS software to identify the main pollution sources and pollution parameters in Beijing,Tianjin region. Secondly,a single pollution source and multi pollution source diffusion model are established combined with the specific case,using Matlab software programming. The model describes the dynamic impact of the surrounding air pollution and air pollution concentration of time and space.
