针对PM2.5含量的影响因素,利用搜集到的2015年1月1日至7月31日蚌埠地区每日的AQI指数和AQI六项基本监测指标数据,建立了多元线性回归模型,对PM2.5含量与其它5项分指标及其对应污染物含量之间的关系进行定量研究,并通过拟合优度检验、F检验、t检验等方法对模型进行检验,最后得到了准确可靠的多元线性回归模型,此模型具有拟合程度高、简易、直观等优势,为多元线性回归模型在PM2.5含量分析中的应用提供了有力参考。
Aiming at the problem about factors affecting the content of PM2.5, Using collected data about January 1,2015 to July 31, 2015 daily AQI index and the six basic monitoring indicators in Bengbu,conducting quantitative research about the relationship between PM2.5 content and other five sub-indicators and their corresponding levels of contaminants by applying multiple iinear regression model,and through the goodness of fit test, F test, t test method to test the model, and finally get accurate and reliable multiple linear regression model,this model has a high degree of fit, simple and intuitive, and other advantages, providing a strong reference for the multiple linear regression model in PM2.5 content analysis.
