Abstract: On the basis of air quality monitoring data of Wuhan urban areas, this article uses SPSS to conduct an independence test among basic indexes of air quality. The resulst show that different index variables are not independent, which means they are related to each other. And then it carries out a correlation analysis among these indexes again, and uses SPSS to calculate their correlation coefficients in order to find out whether the correlation between variables is significant. The results indicate that PM2.5 has significant correlations with five other basic monitoring indexes. At last, the article builds a stepwise regression model of PM2.5 and other five basic monitoring indexes, which inspection prediction proves that the model is ideal.
Key words: Wuhan; PM2.5; independence; correlation; stepwise regressionendprint
