Abstract
Aiming at the impact relationship between urban air qualities, this paper uses correlation analysis methods to study the spatial correlation distribution characteristics of urban air quality and its relationship with topography, and uses the partial correlation and multiple correlation analysis to explore the impact degree between cities in the strong correlation region, as well as the city atmosphere type. The results show that: (1) There is a significant correlation between urban air quality in Henan province, the correlation is linear with distance, and propagation ability is inverse proportional with terrain elevation; (2)The province's air quality presents three independent systems and four relevance belt, the cities in the northern area have north-south correlation characteristics, and the cities in the central area have northwest-southeast correlation characteristics; (3)The cities whose air quality is greatly affected by neighboring cities in the topography are distributed along the 250m elevation belt, Luohe, Zhengzhou and Anyang are air pollution radiation cities, which greatly affect the air quality of Xuchang, Zhumadian, Xinxiang and Hebi.
