基于主成分分析法对河南省大气主要污染物关系的研究
Study on the Primary Air Pollutants of City in Henan Province Based on Principal Component Analysis
摘要
Abstract
The SO2,NO2,PM10,PM2.5,CO,O3in 17 cities of Henan Province were analyzed and cal-culated using the principal component analysis.Three factors that account for 85% of the total variance were extracted to reflect the degree of air pollution.Then three principal component factors were identi-fied 1)PM10, NO2;2)CO, O3;3)PM2.5, SO2.Three principal component contribution rates were 52.049%,25.306%,13.947%respectively.Correlation analysis revealed that significant relationship a-mong PM2.5,PM10,SO2,NO2,and which illustrated that they might share a similar pollution sources. O3and CO had a negative correlation.This might be due to they were the important participate in photo-chemical reaction, which showed that there was a certain degree of photochemical pollution in Henan province.The findings could be useful reference for the control of air pollutants in environmental protection.关键词
