摘要

随着我国的经济和城市化迅速发展，PM

2.5

主导的区域空气污染已成为紧迫、突出的环境问题。据相关研究表明，PM

2.5

在不同季节质量浓度差异较大。根据广州市2015~2019年的PM

2.5

月均质量浓度数据，结合大气污染物及气象因素，引入季节指数，建立预测PM

2.5

质量浓度的改进多元线性回归和多层感知器组合预测模型，探析广州市大气污染物中PM

2.5

质量浓度的变化规律。结果表明，用季节指数改进的组合预测模型对PM

2.5

质量浓度进行预测分析，拟合结果良好。使用不同评价指标将组合模型与传统的多层感知器预测模型和多元线性回归模型进行对比，该组合模型的均方根误差(Root Mean Square Error，RMSE)、平均绝对百分比误差(Mean Absolute Percentage Error，MAPE)、平均绝对误差(Mean Absolute Error，MAE)分别比多层感知器模型减少了23.1%、31%、24.2%；比多元线性回归模型减少了35.3%、41.3%、41%。该模型精度均优于传统的多元线性回归模型和多层感知器模型，能更好地预测环境PM

2.5

质量浓度，为优化环境提供参考。

Abstract

In recent years

China's economy and urbanization have developed rapidly

and the development of cities often comes at the expense of the environment. Regional air pollution dominated by PM

2.5

has become the most pressing and prominent environmental problem in China. According to relevant studies

2.5

concentrations vary greatly in different seasons. Based on the PM

2.5

monthly mean concentration data of Guangzhou from 2015 to 2019

combined with atmospheric pollutants and meteorological factors

with the seasonal index introduced

an improved multiple linear regression and multi-layer perceptual combination prediction model for PM

2.5

concentration is established

to analyze the variation law and future development trend of PM

2.5

concentration in Guangzhou. The results show that the combined prediction model with the improved seasonal index is used to predict and analyze PM

2.5

and the fitting results are good. Compared with the multi-layer perceptron prediction model by using different evaluation indexes

the RMSE(Root Mean Square Error)

MAPE(Mean Absolute Percentage Error) and MAE(Mean Absolute Error) of the combined model are reduced by 23.1%

31% and 24.2% . Compared with the multiple linear regression model

the reduction is 35.3%

41.3% and 41% . The accuracy of the model is better than the traditional multiple linear regression model and multi-layer perceptron model

which can better predict environmental PM

2.5

concentration and provide reference for optimizing the environment.
