In the context of advancing territorial spatial planning, China encounters challenges related to inadequate protection and fragmented utilization of landscape resources. As a prominent nation concerning cultural heritage, Italy’s landscape planning system has evolved through three stages: “spot protection-comprehensive conservation-cultural landscape preservation”. This development has led to a three-tiered landscape planning transmission framework encompassing the national, regional, and local levels.?This paper employs the Piedmont Region of Italy as a case study to systematically analyze its innovative experiences in landscape planning methods and regulatory mechanisms. By delineating landscapes into units, compiling a catalog of landscape heritage sites, and conducting landscape feature assessments grounded in subjective perceptions, it integrates natural, historical, and cultural elements to develop a comprehensive landscape baseline map. Furthermore, it adopts a planning regulatory approach characterized by “stricter regulatory control and flexible guidance”, utilizing landscape authorization mechanisms to regulate development activities and guiding local practices with multi-scale objectives and guidelines to realize refined landscape management at the regional level. This study will provide technical pathways and regulatory insights for the comprehensive management of landscape resources under China’s national spatial planning system.
