Taking regional airport in Henan Province and provincial airport group formed by Wuhan and Xi 'an as the research object, the homogenization of regional airport development is studied. According to the characteristics of the airport, the form of the homogeneity of each dimension was deconstructed, the multi-dimensional index was established, and the homogeneity level of each characteristic index was measured . Taking four airport clusters in Henan as an example, the homogenization level was evaluated. According to the calculation results, ArcGIS software was used to draw the homogeneity level of regional airports in Henan Province. The findings reveal that Xinzheng Airport demonstrates high autonomy and international connectivity, whereas Nanyang and Luoyang airports, located in western and southern Henan, face issues of route similarity and identical airport positioning. Additionally, the close proximity between Nanyang and Xinyang airports hampers their expansion due to the limited scale of each city.Consequently, drawing from these outcomes, specific strategies for the coordinated development of Henan Province's airports were proposed, in order to reduce homogenization according to airport positioning and urban development.
