Globalization has become a central concept in contemporary social science, encompassing a wide range of interconnected processes. The relationship between environmental art design and regional culture is one of mutual influence. Our study explored strategies for maintaining and inheriting regional cultural values in environmental design within China. We employed a mixed-methods approach, utilizing document analysis of historical texts and design plans, interviews with design professionals and cultural experts, surveys with environmental design practitioners, and case studies of successful cultural integration projects. The survey (n=30) indicated a strong emphasis on regional cultural integration. Participants valued its role in creating a sense of place and enhancing project attractiveness. Interview analysis identified three key challenges for integrating regional culture: balancing tradition with modern aesthetics, limited designer knowledge about regional heritage, and ensuring meaningful community participation. The case study of the Dazu Ancient Rock Carvings' restoration showcased the use of traditional carving techniques, Buddhist iconography, and contemporary design for a visitor centre. Document analysis revealed how historical design treatises like the Yuán yě emphasized harmony with nature and symbolic elements, evident in Suzhou Gardens. In conclusion, our study demonstrates the importance of regional cultural integration in environmental design within China.
