摘　　要：针对空气污染问题,运用正交因子法建立了空气质量评价指数模型,总结出主要污染源的性质.通过建立单点源空气污染物扩散模型和多线源空气污染物扩散模型,描述了北京市二环、四环和六环的空气污染物空间分布状况,可为该地区空气污染的治理提供参考.In order to estimate the influence of air pollution, an air quality evaluation index model based on orthogonal factorization method was established and the nature of the main pollution sources was summarized. Through the single point source air pollution dispersion model and the multilinear source air pollution dispersion model,the spatial distributions of air pollutants in Beijing Second Ring,Fourth Ring and Sixth Ring roads were described, which can provide some reference for the local management control of air pollution.
