Abstract

In order to accurately and comprehensively study the development history and economic impact of China's air transportation in recent years, this paper uses the GIS spatial analysis method, the gravity model and the k-means clustering method to construct a spatial connection model and a center classification model respectively. Based on the aviation data of 26 major cities in China, this paper studies the development scale, connection strength, spatial structure and center class of air transportation from the perspectives of passenger and cargo traffic. Research shows: Beijing, Hangzhou and Tianjin are the primary center of air transportation in China. The air transport scale in China has increased, and a complex network structure has been formed. China's top three cities for the connection strength of air transportation are Beijing, Shanghai and Guangzhou.
