摘要
针对成都市空气中的PM_(2.5),从影响AQI指标的六个因素的探究为切入点,构建了主成分分析模型和高斯烟羽扩散模型,运用MATLAB、Excel等软件对数据进行处理,探索了PM2.5的成因、演变等一般性规律,结合所得结果为当地政府提出了相关建议。
This paper, aiming at the PM2.5 problem in the air of Chengdu, constructed the principal component analy- sis model and Gaussian diffusion model from the six factors which affect the AQI index. The data were processed by MATLAB and Excel. It also explored the causes, evolution and other regular laws of PM2.5. Combined with the re- sults, wehoped to make recommendations for the local government.
