Planning Innovation for High-speed Rail New Towns Based on the "Five-Integration" Theory

Traditional urban planning has long suffered from urban homogenization and functional fragmentation. This paper proposes an innovative “Five-Integration” methodology that integrates urban planning, industrial planning, commercial planning, tourism planning, and urban thematic culture. Taking Changsha East High-speed Rail New Town as a case study, the paper systematically demonstrates the practical application of this methodology in regional positioning，industrial planning, functional layout, and development phasing. The research provides theoretical references and practical guidance for promoting high-quality development of high-speed rail new towns in the new era.
