A Brief Analysis of Metro Public Art Based on Urban Culture - A Case Study of Zhengzhou Metro

As a significant symbol of modern cities, the spatial art design of metro systems must not only take practical functions into account but also integrate local culture to enhance regional distinctiveness and uniqueness. This approach endows metro spaces with greater individuality and recognizability, transforming them into crucial windows for showcasing urban styles and effective channels for disseminating urban culture and strengthening citizens' sense of cultural belonging. Zhengzhou, the capital of Henan Province, stands as a vital cradle of Chinese civilization. It served as the hinterland where the Three Sovereigns and Five Emperors once lived and acted, forming an axis of Chinese civilization, and bears a profound historical and cultural heritage. The city boasts abundant historical and cultural resources, including Shang Dynasty ruins, the Shang capital site, and Yellow River civilization, along with emerging contemporary cultural trends. Taking Zhengzhou Metro as a case study, this paper examines the application and expressive forms of urban culture in Zhengzhou Metro's public art, and proposes relevant suggestions on how Zhengzhou Metro can better fulfill its cultural functions and highlight urban characteristics.
